In contrast, static electric fields are unable to transfer energy to the electrons due to their conservative nature. The discovery of a 1770 Japanese diary in 2017 depicting auroras above the ancient Japanese capital of Kyoto suggested that the storm may have been 7% larger than the Carrington event, which affected telegraph networks. 14 25 0. Get it as soon as Sat, Aug 15. The painting Aurora Borealis by Frederic Edwin Church is widely interpreted to represent the conflict of the American Civil War.[84]. The lights are seen around the magnetic poles of the northern and southern hemispheres. Clear filters. Clear filters. Arcs can fragment or break up into separate, at times rapidly changing, often rayed features that may fill the whole sky. Scientists have learned that in most instances northern and southern auroras are mirror-like images that occur at the same time, with similar shapes and colours. Another possible explanation for the auroras is that an as-yet-undetected body around the dwarf star is throwing off material, as is the case with Jupiter and its moon Io. Aurora Polar Lights. Other processes are also involved in the aurora, and much remains to be learned. Electrons mainly responsible for diffuse and pulsating auroras have, in contrast, a smoothly falling energy distribution, and an angular (pitch-angle) distribution favouring directions perpendicular to the local magnetic field. [37][38] It is an aurora because it is caused by precipitation of electrons in the atmosphere but it appears outside the auroral oval,[39] closer to the equator than typical auroras. The main findings have been that auroral arcs and other bright forms are due to electrons that have been accelerated during the final few 10,000 km or so of their plunge into the atmosphere. [92] The mainly red aurora was found to be a million times brighter than the Northern Lights, a result of the charged particles interacting with hydrogen in the atmosphere. The bright forms of auroras are produced when downward acceleration not only increases the energy of precipitating electrons but also reduces their pitch angles (angle between electron velocity and the local magnetic field vector). The word "aurora" is derived from the name of the Roman goddess of the dawn, Aurora, who travelled from east to west announcing the coming of the sun. Because the highest parts of the atmosphere contain a higher percentage of oxygen and lower particle densities, such collisions are rare enough to allow time for oxygen to emit red light. Predictive techniques are also used, to indicate the extent of the display, a highly useful tool for aurora hunters. Perfect white or nearly so is unusual though. Particle acceleration provides a complex intermediate process for transferring energy from the solar wind indirectly into the atmosphere. Sometimes it entirely neutralizes them, so that, in effect, no fluid [current] is discoverable in them. Compra 2015 customized 3D Aurora Borealis Series, IPad 2, 3, 4 Cases, Aurora Borealis 3 Cases For IPad 2, 3, 4 [White]. Auroral events of historical significance, Historical theories, superstition and mythology, The name "auroras" is now the more common plural of "aurora", Boström, Rolf "Observations of weak double layers on auroral field lines" (1992) IEEE Transactions on Plasma Science (, Ergun, R. E., et al. Transparent Black and white. Day-to-day positions of the auroral ovals are posted on the Internet.[9]. The aurora can be seen best at this time, which is called magnetic midnight. Dynamos make use of this basic process ("the dynamo effect"), any and all conductors, solid or otherwise are so affected, including plasmas and other fluids. [45] They are ionized or excited by the collision of particles precipitated into the atmosphere. Aurora Polar Lights. Similarly, the Ngarrindjeri people of South Australia refer to auroras seen over Kangaroo Island as the campfires of spirits in the 'Land of the Dead'. The solar wind and the magnetosphere, being two electrically conducting fluids in relative motion, should be able in principle to generate electric currents by dynamo action and impart energy from the flow of the solar wind. [75], Bulfinch's Mythology relates that in Norse mythology, the armour of the Valkyrior "sheds a strange flickering light, which flashes up over the northern skies, making what Men call the 'aurora borealis', or 'Northern Lights' ". Bright auroras are generally associated with Birkeland currents (Schield et al., 1969;[46] Zmuda and Armstrong, 1973[47]), which flow down into the ionosphere on one side of the pole and out on the other. Aurora Borealis Lofoten. Due to the different color spectra present, and the temporal changes occurring during the exposure, the results are somewhat unpredictable. Go ahead. o. Crea nuovo account. Although we didn't end up seeing the Aurora Borealis, she was wonderful at keeping us "entertained" all evening, by sharing her experiences and knowledge with the group. David Malin pioneered multiple exposure using multiple filters for astronomical photography, recombining the images in the laboratory to recreate the visual display more accurately. Different layers of the film emulsion respond differently to lower light levels, and choice of a film can be very important. The original English text of Benjamin Franklin's article on the cause of auroras is available at: shapes of the luminous parts of the atmosphere and a viewer's position, "Simultaneous ground and satellite observations of an isolated proton arc at sub-auroral latitudes", "The great auroral exhibition of August 28 to September, 1859", "The great auroral exhibition of August 28 to September 4, 1859—2nd article", "The great auroral exhibition of August 28 to September 4, 1859—3rd article", "The great auroral exhibition of August 28 to September 4, 1859—4th article", "The great auroral exhibition of August 28 to September 4, 1859, and the geographical distribution of auroras and thunder storms—5th article", "The great auroral exhibition of August 28 to September 4, 1859—6th article", "The great auroral exhibition of August 28 to September 4, 1859—7th article", "On the great auroral exhibition of August 28 to September 4, 1859, and auroras generally—8th article", "On electrical currents circulating near the earth's surface and their connection with the phenomena of the aurora polaris—9th article", "Localized aurora beyond the auroral oval", "Solar causes of the long-term increase in geomagnetic activity", "Solar cycle effects in planetary geomagnetic activity: Analysis of 36-year long OMNI dataset", "Observations of non-conjugate theta aurora", "News and information about meteor showers, solar flares, auroras, and near-Earth asteroids", "Astronomical photographs from David Malin Images", "Magnetospheric source region of discrete auroras inferred from their relationship with isotropy boundaries of energetic particles", "Windows to the Universe – Auroral colors and spectra", "NASA's MAVEN Orbiter Detects Ultraviolet Aurora on Mars | Space Exploration | Sci-News.com", "Occurrence and average behavior of pulsating aurora", "Auroras Make Weird Noises, and Now We Know Why", "News: Acoustics researcher finds explanation for auroral sounds", "New kind of aurora is not an aurora at all", "Steve the odd 'aurora' revealed to be two sky shows in one", "Magnetospheric signatures of STEVE: Implication for the magnetospheric energy source and inter‐hemispheric conjugacy", "Scientists discover what powers celestial phenomenon STEVE", "On the high correlation between long-term averages of solar wind speed and geomagnetic activity", "Evidence that solar wind fluctuations substantially affect global convection and substorm occurrence", "NASA – THEMIS Satellites Discover What Triggers Eruptions of the Northern Lights", "The Fast Auroral SnapshoT (FAST) mission", "On the Great Magnetic Disturbance of 28 August to 7 September 1859, as Recorded by Photography at the Kew Observatory", "Modern science reveals ancient secret in Japanese literature", "Aurorae in Australian Aboriginal Traditions", "Extrait des suppositions et des conjectures sur la cause des Aurores Boréales", "ESA Portal – Mars Express discovers auroras on Mars", "The Venus ultraviolet aurora: Observations at 130.4 nm", "Far-ultraviolet aurora identified at comet 67P/Churyumov-Gerasimenko", "Lightning and charge processes in brown dwarf and exoplanet atmospheres", "Monstrous Aurora Detected Beyond our Solar System", "First Alien Auroras Found, Are 1 Million Times Brighter Than Any on Earth", "A Brief History of Magnetospheric Physics During the Space Age", "The Exploration of the Earth's Magnetosphere", "Aurora – The magnificent northern lights". The charged particles discharge when particles from the Sun hit the inversion layer, creating the noise. This stylish mask is decorated with glass rhinestones. In northern latitudes, the effect is known as the aurora borealis or the northern lights. The Earth is constantly immersed in the solar wind, a rarefied flow of magnetized hot plasma (a gas of free electrons and positive ions) emitted by the Sun in all directions, a result of the two-million-degree temperature of the Sun's outermost layer, the corona. [18] Film and digital exposure to auroral displays is fraught with difficulties. Two factors to consider are the tilt of both the solar and Earth's axis to the ecliptic plane. [68] One o'clock EST time on Friday 2 September, would have been 6:00 GMT and the self-recording magnetograph at the Kew Observatory was recording the geomagnetic storm, which was then one hour old, at its full intensity. Precipitating protons generally produce optical emissions as incident hydrogen atoms after gaining electrons from the atmosphere. Available gauges: 4g, 2g, 0g, 00g, 716" 1/2" 9/16" 5/8" 3/4" Quantity : 1 Piece Material: Glass ..., , Details :: Double Flare White Aurora Borealis Glass Plugs. 22 27 0. The Confederate Army took this as a sign that God was on their side, as the lights were rarely seen so far south. [65][66], The auroras that resulted from the "great geomagnetic storm" on both 28 August and 2 September 1859, however, are thought to be the most spectacular in recent recorded history. 3.2 out of 5 stars 5. [43] These electrons often, but not always, exhibit a peak in their energy distribution, and are preferentially aligned along the local direction of the magnetic field. Transparent Black and white. Related Images: northern lights aurora night sky landscape. A small piece of enamel is missing on the center leaves. In most cases in the north this usually only requires driving for 30 minutes of a city/town and you should be in light pollution free skies. Auroras are the result of collisions between gaseous particles (in the Earth’s atmosphere) with charged particles (released from the sun’s atmosphere). [90] Since comet 67P has no magnetic field, the aurora is diffusely spread around the comet.[90]. "[67] The second auroral event, which occurred on 2 September 1859 as a result of the exceptionally intense Carrington-Hodgson white light solar flare on 1 September 1859, produced auroras, so widespread and extraordinarily bright, that they were seen and reported in published scientific measurements, ship logs, and newspapers throughout the United States, Europe, Japan, and Australia. Auroras have also been observed on Venus and Mars. According to Hearne, the Dene people saw the resemblance between an aurora and the sparks produced when caribou fur is stroked. [49] Her work resulted from data collected by the Explorer 33 spacecraft. The instantaneous distribution of auroras ("auroral oval")[4] is slightly different, being centered about 3–5° nightward of the magnetic pole, so that auroral arcs reach furthest toward the equator when the magnetic pole in question is in between the observer and the Sun. They tend to fade in the opposite order. Transparent Black and white. Pulsations were discovered to originate at or close to the equatorial crossing point of auroral zone magnetic field lines. Aurora Borealis Notte. Aurora Northern Lights. The immediate cause of the ionization and excitation of atmospheric constituents leading to auroral emissions was discovered in 1960, when a pioneering rocket flight from Fort Churchill in Canada revealed a flux of electrons entering the atmosphere from above. 292 338 13. Large geomagnetic storms are most common during the peak of the 11-year sunspot cycle or during the three years after the peak. Clear skies, stable weather conditions, and proximity to the arctic circle make Yellowknife an ideal place to witness this incredible natural phenomenon. The Aurora is an incredible light show caused by collisions between electrically charged particles released from the sun that enter the earth’s atmosphere and collide with gases such as oxygen and nitrogen. Aurora Borealis Freddo. The outer edge sparkles with faceted aurora borealis crystal glass rhinestones that capture the light beautifully! The chronicler has heard about this phenomenon from compatriots returning from Greenland, and he gives three possible explanations: that the ocean was surrounded by vast fires; that the sun flares could reach around the world to its night side; or that glaciers could store energy so that they eventually became fluorescent. 99. This flow is favored by a southward component of the IMF, which can then directly connect to the high latitude geomagnetic field lines. Portland: "Better than with our batteries on. However, this process is hampered by the fact that plasmas conduct readily along magnetic field lines, but less readily perpendicular to them. ... Vedi altri contenuti di Aurora Borealis Observatory su Facebook. Non ora. By a strange twist of physics, the magnetic disturbance on the ground due to the main current almost cancels out, so most of the observed effect of auroras is due to a secondary current, the auroral electrojet. This pretty Weiss bracelet features dark Topaz Aurora Borealis Rhinestones, and White enamel leaves. 3685–3694. Moved by this sight, Fubao became pregnant and gave birth to a son, the Emperor Xuanyuan, known legendarily as the initiator of Chinese culture and the ancestor of all Chinese people.In the Shanhaijing, a creature named 'Shilong' is described to be like a red dragon shining in the night sky with a body a thousand miles long.In ancient times, the Chinese did not have a fixed word for the aurora, so it was named according to the different shapes of the aurora, such as "Sky Dog(“天狗”)", "Sword/Knife Star(“刀星”)", "Chiyou banner(“蚩尤旗”)", "Sky's Open Eyes(“天开眼”)", and "Stars like Rain(“星陨如雨”)". This angle is known as the "pitch angle" of the particle. What is solar max and why is it important. Soothing Aurora Borealis LED Night Light Projector - Music Speaker - Chic Wood Texture Furniture Look - 45 Degree Tilt - 8 Light Modes - Relaxing Ocean Wave Projector for Babies, Kids, and Adults 3.9 out of … A region that currently displays an aurora is called the "auroral oval", a band displaced by the solar wind towards the night side of the Earth. The first ever extra-solar auroras were discovered in July 2015 over the brown dwarf star LSR J1835+3259. 1” diameter Delivery Confirmation and gift box are included in the shipping charge. He wrote about whether they were above or below the clouds, and recalled that under Tiberius, an aurora formed above the port city of Ostia that was so intense and red that a cohort of the army, stationed nearby for fire duty, galloped to the rescue. In a paper to the Royal Society on 21 November 1861, Balfour Stewart described both auroral events as documented by a self-recording magnetograph at the Kew Observatory and established the connection between the 2 September 1859 auroral storm and the Carrington-Hodgson flare event when he observed that "It is not impossible to suppose that in this case our luminary was taken in the act. Northern Lights Sky. This evidence helped to support their theory that 'magnetic storms' are responsible for such compass fluctuations. ... Aurora Borealis Notte. [93], Natural light display that occurs in the sky, primarily at high latitudes (near the Arctic and Antarctic), Several terms redirect here. Please cat walk my other vintage An auroral electrojet index (measured in nanotesla) is regularly derived from ground data and serves as a general measure of auroral activity. Between 1859 and 1862, Elias Loomis published a series of nine papers on the Great Auroral Exhibition of 1859 in the American Journal of Science where he collected worldwide reports of the auroral event.[6]. Auroras result from emissions of photons in the Earth's upper atmosphere, above 80 km (50 mi), from ionized nitrogen atoms regaining an electron, and oxygen atoms and nitrogen based molecules returning from an excited state to ground state. Some O+ ions ("conics") also seem accelerated in different ways by plasma processes associated with the aurora. [78], In 1778, Benjamin Franklin theorized in his paper Aurora Borealis, Suppositions and Conjectures towards forming an Hypothesis for its Explanation that an aurora was caused by a concentration of electrical charge in the polar regions intensified by the snow and moisture in the air:[80][81]. [14][15] Of course if there are clouds, then forget all the above! Green is the most common color. The most common aurora colour which is green, is produced by oxygen molecules located about 60 miles above the earth. Other interesting effects occur such as flickering aurora, "black aurora" and subvisual red arcs. Joan Feynman deduced in the 1970s that the long-term averages of solar wind speed correlated with geomagnetic activity. The lights of the Aurora generally extend from 80 kilometres (50 miles) to as high as 640 kilometres (400 miles) above the earth’s surface. There are no missing stones. The white storks. A geomagnetic storm causes the auroral ovals (north and south) to expand, bringing the aurora to lower latitudes. In 1741, Hiorter was able to link large magnetic fluctuations with an aurora being observed overhead. Variations in colour are due to the type of gas particles that are colliding. Non ricordi più come accedere all'account? Ionospheric resistance has a complex nature, and leads to a secondary Hall current flow. These are relatively infrequent and poorly understood. Some telegraph lines, however, seem to have been of the appropriate length and orientation to produce a sufficient geomagnetically induced current from the electromagnetic field to allow for continued communication with the telegraph operator power supplies switched off. By analyzing a map of crustal magnetic anomalies compiled with data from Mars Global Surveyor, scientists observed that the region of the emissions corresponded to an area where the strongest magnetic field is localized. It has been speculated that stellar winds may be stripping off material from the surface of the brown dwarf to produce their own electrons. These disturbances are sometimes strong enough to alter the trajectories of charged particles in both solar wind and magnetospheric plasma. May not then the great quantity of electricity brought into the polar regions by the clouds, which are condens'd there, and fall in snow, which electricity would enter the earth, but cannot penetrate the ice; may it not, I say (as a bottle overcharged) break thro' that low atmosphere and run along in the vacuum over the air towards the equator, diverging as the degrees of longitude enlarge, strongly visible where densest, and becoming less visible as it more diverges; till it finds a passage to the earth in more temperate climates, or is mingled with the upper air? "Parallel electric fields in the upward current region of the aurora: Indirect and direct observations" (2002) Physics of Plasmas, Volume 9, Issue 9, pp. 473 452 37. [10][11] The southern counterpart, the aurora australis or the southern lights, has features almost identical to the aurora borealis and changes simultaneously with changes in the northern auroral zone. Suppose we work without batteries while we are affected by this trouble." Auroras are more frequent and brighter during the intense phase of the solar cycle when coronal mass ejections increase the intensity of the solar wind. Nitrogen produces blue or purple aurora. As they do so, the "mirror effect" transforms their directions of motion, from perpendicular to the field line to a cone around it, which gradually narrows down, becoming increasingly parallel at large distances where the field is much weaker. Collisions with other atoms or molecules absorb the excitation energy and prevent emission, this process is called collisional quenching. The aurora was located at Terra Cimmeria, in the region of 177° East, 52° South. Both Aurora’s can be seen in the northern or southern hemisphere, in an irregularly shaped oval centred over each magnetic pole. Northern Lights. [26] The phenomenon of pulsating auroras is an example of intensity variations over short timescales, typically with periods of 2–20 seconds. Of course this depends on a lot of factors such as aurora strength (Kp level). Elias Loomis (1860),[6] and later Hermann Fritz (1881)[7] and Sophus Tromholt (1881)[8] in more detail, established that the aurora appeared mainly in the auroral zone. This insight was made possible not only due to scientific magnetometer measurements of the era, but also as a result of a significant portion of the 125,000 miles (201,000 km) of telegraph lines then in service being significantly disrupted for many hours throughout the storm. 217 183 20. It measures 2 inches across. This lovely mid-to-large-sized goldtone brooch pin has an openwork circle design with a raised ribboned accent. It is now disconnected." [89][90] The auroras were observed at far-ultraviolet wavelengths. Such low energies excite mainly the red line of oxygen so that often such auroras are red. Add the right amount of shimmer to your stylish look with this beautiful Aurora Borealis Bracelet with Crystals 18K White Gold Adjustable 7"-9". [17] They discovered that most of the light is produced between 90 and 150 km above the ground, while extending at times to more than 1000 km. Aurora Borealis. Northern Lights. Aurora Borealis Notte. Both incoming electrons and protons may be involved. These ions are accelerated by plasma waves in directions mainly perpendicular to the field lines. Migliaia di nuove immagini di alta qualità aggiunte ogni giorno. However, the earth’s magnetic field is weaker at either pole and therefore some particles enter earth’s atmosphere and collide with gas particles. [32] Ionospheric absorption makes AKR only observable from space. Portland operator: "Will do so. As already mentioned, it happens most readily when the interplanetary field is directed southward, in a similar direction to the geomagnetic field in the inner regions of both the north magnetic pole and south magnetic pole. [33], Aurora noise, similar to a hissing, or crackling noise, begins about 70 m (230 ft) above the Earth's surface and is caused by charged particles in an inversion layer of the atmosphere formed during a cold night. Auroras also occur poleward of the auroral zone as either diffuse patches or arcs,[13] which can be subvisual. Auroras have been observed on both gas planets, most clearly using the Hubble Space Telescope, and the Cassini and Galileo spacecraft, as well as on Uranus and Neptune.[86]. This correlation indicated that the origin of the light emission was a flux of electrons moving along the crust magnetic lines and exciting the upper atmosphere of Mars. Acquista e vendi autentiche calzature adidas T-Mac 3 Aurora Borealis AQ7992 e migliaia di altre sneakers adidas con informazioni sui prezzi e date di uscita. Providing northern lights forecasts for Norway, Finland, Sweden, Iceland and others. Other particles that do not mirror enter the atmosphere and contribute to the auroral display over a range of altitudes. In addition to moving perpendicular to the Earth's magnetic field, some magnetospheric plasma travels down along the Earth's magnetic field lines, gains additional energy and loses it to the atmosphere in the auroral zones. The solar cycle is 11 years. [70], An aurora was described by the Greek explorer Pytheas in the 4th century BC. Aurora Borealis Freddo. They, therefore, start at their "mirror points" and can travel only upward. Compra LG G2 Cell Phone Case Covers White Aurora Borealis dxli. [42] Since then an extensive collection of measurements has been acquired painstakingly and with steadily improving resolution since the 1960s by many research teams using rockets and satellites to traverse the auroral zone. This process is essentially the same as that employed in plasma fusion laboratories throughout the world,[62] and appears well able to account in principle for most – if not all – detailed properties of the electrons responsible for the brightest forms of auroras, above, below and within the acceleration region.[63]. A nice size, In addition, the moons, especially Io, are also powerful sources of aurora. [25], At shorter time scales, auroras can change their appearances and intensity, sometimes so slowly as to be difficult to notice, and at other times rapidly down to the sub-second scale. During magnetic storms, in particular, flows can be several times faster; the interplanetary magnetic field (IMF) may also be much stronger. The varying intensity of the solar wind produces effects of different magnitudes but includes one or more of the following physical scenarios. In excellent condition. Portland: "Very well. Usually the best time of night (on clear nights) to watch for auroral displays is between 10pm to 2am. This type of aurora is generally accompanied by decreasing peak emission heights of about 8 km for blue and green emissions and above average solar wind speeds (~ 500 km/s). For example, the Gunditjmara people of western Victoria called auroras puae buae ('ashes'), while the Gunai people of eastern Victoria perceived auroras as bushfires in the spirit world. [72] It has been suggested that Pliny the Elder depicted the aurora borealis in his Natural History, when he refers to trabes, chasma, 'falling red flames' and 'daylight in the night'.[73]. The long periods of darkness and the frequency of clear nights provide many good opportunities to watch the auroral displays. The other most important is to be on relatively high ground with an un-obscured view north (this is not necessary if you are so far North the auroras are usually directly overhead). The cusps of the magnetosphere, separating geomagnetic field lines that close through the Earth from those that close remotely allow a small amount of solar wind to directly reach the top of the atmosphere, producing an auroral glow. Collisions become more frequent progressing down into the atmosphere due to increasing density, so that red emissions do not have time to happen, and eventually, even green light emissions are prevented. Aurora Borealis Lofoten. Inexplicably though, some authors[58][59] still invoke quasi-static parallel electric fields as net accelerators of auroral electrons, citing interpretations of transient observations of fields and particles as supporting this theory as firm fact. The aurorae on Saturn seem, like Earth's, to be powered by the solar wind. [20] Terrestrial features often find their way into aurora images, making them more accessible and more likely to be published by major websites. 32 27 2. Savlano 14K White Gold Plated Aurora Borealis Drop Cut 18 Inches Pendant Chain Necklace For Women & Girls 4.6 out of 5 stars 16 $13.99$13.99 FREE Shipping on orders over $25 shipped by Amazon That alone would tend to line them up in the Sun-Earth direction, but the rotation of the Sun angles them at Earth by about 45 degrees forming a spiral in the ecliptic plane), known as the Parker spiral. Aurora during a geomagnetic storm that was most likely caused by a coronal mass ejection from the Sun on 24 May 2010, taken from the ISS, Diffuse aurora observed by DE-1 satellite from high Earth orbit, According to Clark (2007), there are four main forms that can be seen from the ground, from least to most visible:[23], Brekke (1994) also described some auroras as curtains. It is not well understood, but geomagnetic storms may vary with Earth's seasons. They believed that the lights were the spirits of their departed friends dancing in the sky, and when they shone brightly it meant that their deceased friends were very happy. ", The conversation was carried on for around two hours using no battery power at all and working solely with the current induced by the aurora, and it was said that this was the first time on record that more than a word or two was transmitted in such manner. Vintage Aurora Borealis White Rhinestone Snowflake Pin Brooch. It may show slight signs of use and wear. FREE Shipping by Amazon. All prong set on a silver tone skip chain. [25] The similarity to curtains is often enhanced by folds within the arcs. The connection between Auroras and sunspot activity has been suspected since about 1880. The high latitude magnetosphere is filled with plasma as the solar wind passes the Earth. Auroras are occasionally seen in latitudes below the auroral zone, when a geomagnetic storm temporarily enlarges the auroral oval. The resulting ionization and excitation of atmospheric constituents emit light of varying color and complexity. [69] The following conversation occurred between two operators of the American Telegraph Line between Boston and Portland, Maine, on the night of 2 September 1859 and reported in the Boston Traveler: Boston operator (to Portland operator): "Please cut off your battery [power source] entirely for fifteen minutes." 920 1016 86.
