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.

Crack and Bang

A crack in Earth's magnetic field this morning and bang, the solar wind drops in ... leaving us with this

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.

Ringing Like a Bell

Earth's magnetic field is ringing like a bell - go to http://spaceweather.com 22nd February ... a stream of solar wind is passing just south of the Earth making a grazing contact with the magnetosphere. This is causing the unusual swinging back and forth that is like a ringing bell. The low frequency oscillation went on for over an hour. In spite of the glancing blow it did cause auroral lights over the Arctic - see image below taken in Lapland.




It seems that when the Sun is more active than normal, with lots of flares, some of which are directly aimed at the Eaarth, the ozone hole over the poles appears (as ozone is dispersed to temperate and tropical areas of the Earth (the atmosphere overlying these regions). The zone hole was particularly a focus of interest in the 1990s and early 2000s. It was back to a degree in the middle of the current solar cycle (or solar maximum as it is known).

HINODE images

At https://phys.org/print437129335.html ... HINODE captures record breaking solar magnetic field. A sun spot observed by the HINODE spacecraft. Astronomers in Japan discovered the largest magnetic field ever directly measured on the surface of the Sun. It seems to have been generated as a result of gas outflow form one sun spot pushing up against another sun spot .... (see below)

Magnetic Poles

William sent in this link - www.yahoo.com/news/earth-apos-magnetic-poles-show-185939488.html ... apparently, earth's north and south magnetic poles, in the past, used to flip regularly, at 200 to 300,000 years intervals. Currently, we are led to believe, the poles have not flipped for the last 780,000 years. Is the dating methodology haywire and why do magnetic poles flip?

Electric Saturn

Robert sent in the link to https://expertsvar.se/en/pressmeddelanden/electrical-and-chemical-coupli... ... electrical and chemical coupling between Saturn and its rings - Swedish research results published in the journal Science. The Langmuir probe was developed by the Swedes and was onboard the Cassini spacecraft. It seems it has made some exciting discoveries on the atmosphere of Saturn - a strong coupling, chemically and electrically, between Saturn's upper atmosphere and its ring system.

gravitational waves

William forwarded a link to a video of Wal Thornhill - go to https://www.youtube.com/watch?v=SFJjrD5pq_I ... which questions the idea gravitational waves were really detected and the actual existence of black holes.
