Sun Mystery

There was an outbreak of auroral displays on Friday the 20th April - across the Canadian border and lighting up Illinois and Indiana (and many other States). The display was caused by an inteplanetary shock wave according to http://spaceweather.com (April 23rd) - but there is a mystery. The shock waves are supersonic disturbances in the solar wind which cause discontinuities in the speed, temperature, and density of the plasma. During periods of high solar activity these are routinely delivered to Earth by corononal mass ejections (CMEs) - explosions on the Sun.

What are neutrinos?

Neutrinos betrayed their existence through their absence. In 1914 physicist James Chadwick was looking at beta decay - a from of radiactive decay in which a nucleus emits an electron and transforms a neutron into a proton. Conservation of energy appears to be an accepted Law of physics (although that might be providing it with a bigger status than warranted). Suffice to say the mainstream position supports the idea so that electrons from a particular nucleus, such as lead-214, should always emerge with the same energy.

Solar Spicules

In Science journal 356 issue 6344 23rd June 2017, under the heading Solar Physics, there is a nice article on the NASA discovery of solar spicules (see also www.sciencemag.org/content/352/6344/1269 and www.nasa.gov/feature/goddard/2017/scientists-uncover-origins-of-the-sun-... ....). The Science piece was forwarded by Jovan and I have probably already posted this story (last year) but it has come up again on Eric's thread on Velikovsky (and his works). The piece is about solar spicules and Alfven waves.

A Purple Steve

   ... The thin ribbon of purple light can be seen with the green aurora in the background - apparently some distance behind the purple Steve. What causes the purple colour? The image comes from the Alberta Aurora Chasers - and one Notanee Bourassa (who was photographing in the garden with his children). The phenomenon is known as a Steve - see https://phys.org/print440264089.html .... Steve is what it is called in a study at Science Advances (March 2018).

Electro Blobs

New research using clays vessels used in cleansing rituals by Iron Age farmers shows that over the last 1500 years an electromagnetic anomaly has waxed and waned. Think about that.

Magnetic field decay

Robert sent in this link ... https://crev.info/2018/03/earth-magnetic-field-still-decaying/ ... Robert suspects that instead of a young earth scenario the Earth's orbit may have recently changed - or the heliosphere. Either one or the other or a combination of both. He suggests Earth has yet to regain electricl equilibrium.

Polygonal Poles

Robert sent in this link - https://astronomynow.com/2018/03/07/new-juno-findings-amaze-scientists-s... ... The spacecraft Juno has come up with data that have surprised scientists. Robert comments, both Jupiter and Saturn show a pattern of polygonal structures at their planetary poles. In his opinion, the Earth does too (a spreading system surrounding Antarctica). NASAs Juno spacecraft shows Jupiter's weath systems extend much deeper than previously believed and the huge planet rotates nearly as a rigid body below racing jet streams, storms, and cyclones.
