Magnetotail Explosions

Robert also sent in this link to the discovery of explosions in Earth's magnetic tail - buffetted by a stream of solar wind (but see earlier post at https://sis-group.org.uk/news/musical-wave.htm ). Go to www.gizmodo.co.uk/2018/11/spacecraft-witness-explosion-in-earths-magneti... ... which is derived from https://arxiv.org/ftp/arxiv/papers/1809/1809.06932.pdf ... and the claim is that this is evidence of magnetic reconnection events. Robert says that what is really happening is that double layers are accelerating electrons (electron jets) etc.

Musical Wave

At http://spaceweather.com 23rd November 2018 ... musical waves in Earth's magnetic field (see also https://wattsupwiththat.com/2018/11/23/our-quiet-sun-produces-musical-wa...) ...  our quiet Sun produces musical waves in Earth's magnetic field. A space weather observatory in Norway (above the Arctic Circle) has this week detected sine waves of exceptional purity rippling through Earth's polar magnetic field. For some reason the comments at the second link are not exactly impressed - but you can't please everyone.

Aurora Energy

At https://phys.org/print461478434.html ... the study of auroras has revealed a new way of understanding the physics of explosive energy released in space according to new research published in Nature Communications (although precisely what that might be is not forthcoming in the press release). The researchers come from Reading University and University College London. Somewhere in the huge volume of space into which Earth's magnetosphere stretches is a clue to that energy - and the authors set about finding it.

Plasma Instabilities

At http://spaceweather.com ... (November 14th, 2018). Radio lasers on Jupiter produced as a result of plasma instabilities - sounds almost like the EU. They are produced in the magnetosphere of Jupiter as a result of interaction with it's moon Io. In the normal course of events Jupiter's known radio emissions are weak by the time they reach the vicinity of the earth and only spacecraft in the vicinity of the planet can detect them.

Mountain Building

At https://www.thunderbolts.info/wp/2016-05-11/arc-blast-part-1/ ... this subject popped up the other day in the study group meeting. I thought I would have a read - and the invitation is for anyone else to do the same. Make up your own mind. Andrew Hall chose electric processes around the poles to explain mountain building (or at least the pointy tops of mountains) which he says is decisive evidence of the EU theory.

1972 and All That

At http://spaceweather.com (November 9th 2018) ... we have a story about space weather during the Vietnam war.  In 1972 a giant sun spot let loose with a blast of solar wind (plasma) in a series of X-class flares which caused radio black outs on Earth. One plasma plume, or CME, travelled between the Sun and the Earth in just 14.6 hours. This is in contrast to recent movements that take two to three days. The resulting geometric shower sparked auroras so bright they cast shadows in countries as far south as Britain.

Electrified Space Dust

At https://phys.org/print460636942.html ... electrically charged dust arranges itself in straight lines in the laboratory. Space dust is also electrically charged as it collects electrons from plasma gas - such as the solar wind. This was discovered in an experiment on the International Space Station where gravity is weaker that in an earth based laboritory. Nevertheless, dust also arranged itself in straight lines.

Valentina Zharkova

Benny Peiser introduces Valentina Zharkova at https://www.thegwpf.org/professor-valentina-zharkova-the-solar-magnetic-... .... in a talk (watch the video) on how the solar magnetic field may affect climate on the earth. She begins by telling us that sun spots are dark and cooler regions on the surface of the Sun. Basically, she is predicting a solar minumum and cool weather between 2020 and 2055. Is that one in the eye for the alarmists - or a case of alarmism at the opposite end of the spectrum (cooling instead of warming).

Fire in the Atlantic

Sent in by Robert. An interesting story at https://earthobservatory.nasa.gov/images/144141/a-fire-in-the-middle-of-... ... the Visible Infrared Imaging Radiometer- Suite on the Suomi NPP satellite captured thermal anomalies off the coast of Brazil (in the South Atlantic). The thermal anomaly means an area flagged by the satellite as unusually warm. Most such anomalies captured by the satellite are fires but obviously there is no fire burning in the middle of an ocean. Natural gas flares also trigger thermal anomalies but they are only found in shallow water locations.

SIS Autumn Meeting

Slides from Bob Johnson's two talks at the September SIS speaker meeting are available to read on the web site in case anyone is unaware of how to view them. Simply click on the blue text on Autumn Meeting and the two links will pop up on the next page. The first talk concerns the differences between the Plasma Universe as espoused by the likes of Alfven and Perratt, and the Electric Universe as outlined at Thunderbolts web site.
