... The storm began quite unexpectedly. The strongest geomagnetic storm for the last seven months began on Earth almost precisely at the same time as the solar eclipse reached its maximal stage, the culmination of which occurred at GMT 02:35 (06:35 Moscow time). ... Oscillations of such amplitude in the magnetic field have not been observed since October, 11th of last year, which is more than seven months ago. ...

William Gilbert . The north-south pointing property of the compass needle was discovered in China around the year 1000, and in 1600 William Gilbert in London showed that this could be explained by the entire Earth being a huge magnet. As a model for the magnetic Earth he used a spherical magnet, which he called "terrella" , the "little Earth." He moved a small compass over the surface of the terrella and demonstrated that it always pointed towards its magnetic poles. ... Magnetic Fields . ...

One of the rarest but most interesting effects which can be observed with the Irkutsk IS radar is anomal high power signal registraion(coherent echo) due to strong magnetic storms. ... These signals are formed at E-layer heights in the presence of a strong electric field which causes particles to drift. ...

SPACE WEATHER . The response of our space environment to the constantly changing Sun is known as space weather. ... Some of the most dramatic space weather effects occur in association with eruptions of material from the solar atmosphere into interplanetary space. ... Space weather disturbances are generally caused by solar storms. ... the Sun. ... Every object in the solar system experiences the equivalent of Earth's space weather, although its detailed characteristics differ from place to place. ...

Next: A Universal Diagram for Up: ``Ecology'' of Magnetic Rotators Previous: The Corotation Radius . The interaction of a magnetic rotator with the surrounding plasma to a large extent depends on the relation between the four characteristic radii: the stopping radius, , the gravitational capture radius,   , the light cylinder radius,   , and the corotation radius,   . ... Hence, the classification of the interaction regimes may well mean the classification of magnetic rotators. ...

Galileo Finds Giant Iron Core in Jupiter's Moon Io . Jupiter's volcano-pocked moon Io has been found by NASA's Galileo spacecraft to have a giant iron core that takes up half its diameter, scientists report in today's issue of Science magazine. The spacecraft also has detected a large "hole" in Jupiter's magnetic field near Io, leading to speculation about whether Io possesses its own magnetic field. If so, it would be the first planetary moon known to have one. ... Space History Galileo . ...

... Jitter is usually very small in magnitude and random in effect, and is not expected to lead to systematic throughput changes. ... However, such a change should lead to an obvious decline in the strength of the comparison lines at one end of the spectrum relative to the other and not an overall decline in counts. No such effect is seen (the counts decline evenly from one end of the spectrum to the other). ... The value changes steadily, but not by enough to account for the changes in counts seen. ...

... The air just sit there and doesn't get stirred. ... Normally, the air is hottest near the ground and gets cooler as you go up. ... If it weren't for the temperature profile, convection wouldn't occur: Because the temperature decreases with altitude, cold air sits on top of hot air, allowing convection. ... The air above the ground is hot, the air above the water is cold. ... The land cools down faster than the sea, so the air above the ground is colder than the air above the water. ...

... GCR and SCR are primary cosmic rays. 10-15 years after the discovery of cosmic radiation (1919) there emerged two main avenues of investigation in the physics of cosmic rays (CR): 1) nuclear - elucidation of the origin of elementary particles and nuclear interactions; and 2) astrophysical (space physics) - solution of the problem related to the origin and variations (changes in intensity) of CR. ... Besides, the CR flux in interplanetary space is, strictly speaking, not isotropic. ...

... The ancient chronical said about the colour rings around the Sun and the Moon, about three suns in the sky, light columns, bright lightning, different "comets" rushing to the Earth, moving among the stars or round the Earth with the sky. All these occurrences may be divided into three categories: one that occur in the near or far space, processes going on in the Earth atmosphere under the influence of cosmic factors and at last the occurrences connected with the Earth atmosphere. ...

Although seen here on Earth, aurorae start at the center of the solar system. ... After about three days those particles get near the Earth and hit the Earth's magnetic field. ... Now these particles are moving very fast, and when they hit the air they slam into air atoms that make up our atmosphere, sometimes knocking loose more electrons. ... 2008 Phil Plait. ...

... The Sun is the closest star to us, and a regular object in our Galaxy. Solar activity manifests itself, primarily, in solar flares - episodic explosive energy release in the form of electromagnetic radiation and high energy particles (electrons and protons). The nature of the flares is related to cyclic variations of global and local magnetic fields in the atmosphere of the Sun. ... Such formations are called active regions. ...

... part 1 | ... The Basic Stages in Earth's Pre-geological Development . ... After fragments of the Vortex sleeves separated, whirlwinds of second and third orders ("NC" - new micro-vortex) were generated- future planet cores and their satellites - all of them developing independently, governed by the common laws of development of cosmogenic vortexes. ... Our planet's core today is comprised of considerably deteriorated cosmogenic vortex; consequently, the Earth has a moderated magnetic field. ...

Using the European Space Agencyт??s (ESA) Cluster and Mars Express missions to provide data from Earth and Mars, respectively, scientists compared the loss of oxygen from the two planetsт?? atmospheres as the same stream of solar wind hit them. ... Venus will provide an important new perspective on the issue because, like Mars, it has no global magnetic field, yet it is similar in size to Earth and has a much thicker...
