... the observation schedule. The observation plans for Jupiter during this encounter period include a more or less standard set of observations: brightside and darkside maps, North-East-West-South maps, North-South strips, hot spot observations, regional and thermal maps. These observations are complimented by a set of observations that concentrate on the north polar region of Jupiter's atmosphere, including aurora and regions known as haze zones. These haze zones, as their name suggests, are regions of hazy clouds that are associated with and driven by the production of aurora on Jupiter. The observations of these regions will be coordinated among all of the remote sensing instruments for a complete understanding of the processes involved in the production of these ...

... their plasma sheaths touch. In the case of a comet, its plasma sheath can measure millions of kilometers across. Travelling at 20 kilometers per second, a comet will cover one million kilometers in about 14 hours. So, for something of the order of a day, there will be odd electrical effects evident in weather, geomagnetism, auroras and possibly earthquakes. The electrical stress will finally build to the point where an electrical discharge will fly between the earth and the intruder with the strong likelihood that the intruder will be disrupted. This seems to have been the case for .. . Tunguska where the bolide was destroyed before hitting the ground. EYEWITNESS ACCOUNTS: Curious Sun ...

... Our sun would fit right in," Schaefer says. He and Rubenstein presented their results today at the American Astronomical Society meeting in Austin. DELIGHTFUL TO DISASTROUS If the sun ever threw out a superflare, the results on Earth could range from pretty to devastating. The superflare would accelerate protons and other particles speeding toward Earth, brightening the auroras from a near-the-poles sight to one filling the world's night skies. On the downside, "Kiss our satellite fleet goodbye," Schaefer says. The high-speed particles, even from a small superflare, would fry the satellites' electronics. The surge of electricity from the charged particles would also likely blow out electrical power grids around the world ...

65. Hannes Alfvén (1908-1995) [Journals] [SIS Internet Digest]
... founder of magnetospheric physics, the great Norwegian scientist Kristian Birkeland. At the end of the nineteenth century Birkeland had laid out a compelling case-supported by theory, laboratory experiments, polar expeditions, and a chain of magnetic-field "observatories" around the world -that electric currents flowing down along the earth's magnetic fields into the atmosphere were the cause of the aurora and polar magnetic disturbances. However, in the decades following Birkeland's death in 1917, Chapman became the acknowledged leader in interplanetary and magnetospheric physics. Chapman proposed, in contradistinction to Birkeland's ideas, that currents were restricted to flow only in the ionosphere with no downflowing currents. Chapman's theory was so mathematically elegant that it gained wide acceptance over ...

... said Tsurutani. Instead, they found that the ends of Alfven waves always have both rotational and tangential characteristics. Like the movements of a plucked guitar string, Alfven waves travel down the magnetic fields that emanate from the Sun. Disturbances in the Sun's magnetic field, which is embedded in the solar wind, travel through space to eventually cause auroras on Earth. The high-energy particles from the solar wind become trapped in the Earth's magnetic field and come down into the atmosphere near the Earth's north and south magnetic poles. The highly-charged particles then collide with oxygen and nitrogen in Earth's atmosphere and emit light, forming the aurora. Tsurutani also studied polar plumes, long trails from the base ...

... new high technology experimental research, he there argued that "numerous rock art designs...can be linked to the recording of a highly visible outer space event that occurred many millennia ago."  As he there indicated, "many items of antiquity including petroglyphs...are interrelated by world-wide observations of an intense aurora' that may have lasted for centuries."  All of this is not to say that all petroglyphs, or other ancient symbols, are identifiable as plasma instabilities. Neither can it be said that those which are so identifiable pertain to the same series of events. As I aim to indicate in future works, some ...

... in the middle of the Canadian Northwest Territories as the "glaciers" of the last "ice age" never extended into Siberia, which was apparently more temperate at the time. (See also footnote 13 of Part II, KRONOS IX:3 .) The "red hand of death" spoken of in ancient legends may have been auroras caused by the current sheet between the comet Venus and Earth, just as Io's current sheet causes visible auroras as it passes over Jupiter's dark side; or, it may have been the visual effects of flaming hydrocarbons (oils and tars) as they rained into Earth's atmosphere from Venus' huge cometary tail. The columns of smoke extending ...
69. On Morrison: Some Final Remarks (Forum) [Journals] [Kronos]
... electrons per cubic centimeter are encountered. Near Venus' surface gas density exceeds this by more than ten orders of magnitude. While one billion electrons per cubic centimeter is a high electron density, it is not impossibly large, especially above a planet where the lowest thirteen kilometers of the atmosphere are glowing. Electron density during a display of atmospheric aurora above Earth exceeds ten million per cubic centimeter. An electric discharge, not unlike an aurora, has been proposed as the cause of Venus' lower atmospheric glow. If this glow is electric, the relief detected using radar could be attributed in part to variability in the electron density within the glow. So, we must view the ...

... of a fiery pillar spanning the heavens. The luminous pillar associated with the polar configuration was a dynamic phenomenon, alternately presenting evolving phases or forms, an apparent signature of a plasma-generated structure, where plasmas are defined as "quasi-neutral assemblies of charged particles."  Familiar examples of plasma include the solar wind, lightning, and auroras, the latter produced when the solar plasma filters through Earth's atmosphere, interacting with, and exciting, the molecules in Earth's upper atmosphere.  While, during one particularly memorable phase, the plasma column stood erect like a giant pillar- a veritable universalis columna- during other phases it took on a helical or zigzagging form ...
