Electromagnetism news


At http://spaceweather.com March 15th, news of a geomagnetic storm warning, a CME on the Sun that is earth facing. Direct hit expected, on sunday the 17th.

The Met Office has predicted a return to colder weather next week in the UK, and today, the 16th, it is snowing in New York (and no doubt elsewhere in the US).

The story is also at http://phys.org/print282578267.html - but here the only worry is with satellites and communications systems. The weather is not mentioned.

Source of the Solar Wind?

At http://tallbloke.wordpress.com/2013/03/11/nasa-solar-wind-energy-source-... ... NASA think they might have found the origin of solar wind via the WIND spacecraft )see http://science.nasa.gov/media/medialibrary/2013/03/08/splash_big.jpg). The source of the heating of the solar wind appears to be ion cyclotron waves and these are made of protons tha circle in wave like rhythms around the Sun's magnetic field. Ion cyclotron waves emanate from the Sun and accelerates the solar wind.

The mathematics of the solar wind

At http://phys.org/print280693945.html ... scientists are looking further into the solar wind, the stream of particles and electro-magnetic waves that originate in the Sun and are deflected, mostly, by the protective bubble around the Earth, the magnetosphere. Alfven waves have now been mathematically equated - by a scientist at NASA Goddard. These equations can now be used to predict and evaluate the imput of the solar wind and the consequence of this is that they will be embedded in climate models.

Supernova Saturn

At www.dailygalaxy.com/my_weblog/2013/02/saturns-shockwaves-reach-supernova... ... the Cassini spacecraft is said to have struck a strong blast of solar wind as it orbited the planet Saturn - and super high energies. It continues by comparing this to the acceleration of energy around distant supernovae. They are referring to the shock waves created as the solar blast strikes Saturn's magnetic field.

Monsoons in China fluctuate with Solar Activity

This is an interesting scenario and is used by Pierre Gosselin at http://notrickszone.com/2013/02/07/monsoons-in-china-fluctuate-in-sync-w... ... as a discovery disputing co2 influenced warming - yet it is the possibility it may pump up the role of the Sun and CMEs that might well in the long term be significant.

Fifty Million Cosmic Rays

At http://tallbloke.wordpress.com/2013/02/04/nasa-balloon-mission-detects-5... ... the balloon mission over the Antarctic has discovered large numbers of cosmic rays according to a press release - some 50 million and counting. See also www.wff.nasa.gov/baloons

Aurora experiment

At http://phys.org/print278935705.html ... an experiment is described that involves firing a rocket into the sky above Alaska in order to study auroral wind - a stream of oxygen atoms derived from Earth's atmosphere under the influence of the aurora. Normally, the amount of oxygen involved would not gain enough traction but in this scenario it can gain enough energy to avoid gravity - among other things. The study seeks to understand how this happens.

The lunar dynamo model?

At www.dailygalaxy.com/my_weblog/2013/01/the-moon-was-once-powered-by-a-dyn... ... it seems scientists have found evidence that rocks on the moon were magnetised millions of years ago. This discovery has led to the idea the moon formerly had a metallic core that produced the magnetic field - a lunar dynamo. It is thought a dynomo exists at the heart of the Earth.

The Earth in an electric solar system

The Earth in an electric solar system is a paper by Louis Hissink in the New Concepts in Global Tectonics Newsletter, a link forwarded by the contacts tab by member Robert Farrer, and you can find it by going to www.ncgt.org and scrolling down to issue 51, clicking on and downloading the full pdf of that issue. Once downloaded you pick which pages you might want to print out. This paper is fairly short in comparison to some of them.
