plasma in harmony

   At http://phys.org/print356081070.html ... the ESA Cluster satellites (a group of four satellites closely orbiting on a near trajectory, have observed noise waves inside the Earth's magnetosphere. In a region of space about 12,000 mile upwards the four satellites have seen a stack of 13 space plasma stripes ... see image above.

polygonal cratering

At New Concepts in Global Tectonics journal, 3:2 June issue of 2015 (www.ncgt.org), there is an interesting paper, some 26 pages in length (lots of illustrations) that claims cratering on earth is not as simple as mainstream would have believe (and the same goes for other cosmic bodies such as Mars and the Moon). Cratering is erroneously lumped together as entirely due to meteoroid and asteroid impacts.

Cosmic Lightning

I'm not referring to space lightning - or electrical phenomena in far away galaxies, but the normal earth system kind of lightning, of the everyday everywhere thunderstorm. According to a new model of its behaviour lightning has a cosmic trigger - go to http://phys.org/print354951242.html ...

exploding sprites

At www.newscientist.com/article/dn27803-slomo-reveals-how-enigmatic-sprites... ... is one of those stories that has popped up at a lot of web sites and blogs - even at WattsUpWithThat. At the link above (and elsewhere) there is a video of a sprite above a thunderstorm, and how the lightning phenomenon appears and then just as quickly disappears. Gary Gilligan has forwarded his view that sprites appear in mythology as flowers.

Don Scott

SIS member Adam Stuart has been keeping some of us up to mode on the current Thunderbolts conference in the US. He has forwarded links to www.ptep-online.com/index_files/2015/PP-41-13.PDF and https://m.youtube.com/watch?v=fVsON1c3OUY

The first is to an article by Don Scott which has been published in the journal Progress in Physics. The video is a recording of aurora over northern Scotland which I've passed on to various people as it is pretty dramatic. See what you think.

the colours of light

I like, now and again, to have a delve around Malaga Bay, sticking a finger in to find a plum to extract. At https://malagabay.wordpress.com/2015/06/17/deprecating-photomagnetism/ ... which is all about the mainstream dismissal of the idea that sunlight has the ability to magnetise objects on the surface of the earth, and its remarkable resuscitation in 2011, an experiment that promises to make technology cheaper to produce and therefore more readily available to human beings.

Thunderbolts Conference

At www.thunderbolts.info ... Wal Thornhill has been talking about the Rosetta mission to Comet Churyumov-Gerasimenko. There is also an analysis of cometary electro-chemistry by Franklin Anariba.

The conference is available for people unable to attend but have internet access - go to site for details.

plasma in 3D

  Cleo Loi, a student at the University of Sydney, has found that by using telescopes in a certain way she could see plasma structures way up high in the atmosphere. The above image is an artist's impression.

drought breaks and sprites prosper

The drought in some parts of Texas and the southern Plains has dramatically come to an end with huge thunderstorms and lashing rain last weekend (May 23rd) - see www.spaceweather.com for May 28th. Lightning bolts were prominent - and sprites. These could be seen shooting up from the top of thunder clouds - but they are a space weather phenomenon. They develop at around 80km altitude and grow in both directions, downwards and upwards, as electric forces shoot to the top of the atmosphere.

 

 

windy, windy

A paper by Nils-Axel Morner in Energy and Environment, volume 22 No 3 (2011), 'Arctic Environment by the Middle of this century' (being the 21st century in question) which goes on to claim, contrary to the global warming hypothesis, that we are entering a cooler weather episode in the northern hemisphere. Morner is a CAGW hate figure - and very long in the teeth, so a certain amount of scepticism is desired as he appears to enjoy rocking the boat of settled science.
