Sprite at Night

   .... this image comes courtesy of http://spaceweather.com (June 23rd 2018) a sprite above a thundercloud taken by a pilot flying to Las Vegas from London, Brian Whittaker. The green bands are not auroral in nature but air glow - caused by chemical reactions in the upper atmosphere. Whittaker comments, the sprites are really high up in the atmosphere and he has probably missed them in the past by looking downwards.

Jelly Fish Sprites

Storms and lightning over central Europe produced a spectacular display of sprites - see http://spaceweather.com (11th June 2018). Some 250 sprites were seen in just four and a half hours from the vantage point of the Czech republic (looking across the Hungarian Plain). The jelly fish sprites (see below) were very large - at the same time there was strong cloud to ground strokes inside a convective storm.

 

 

Electric Dark Matter

At https://phys.org/print446911328.html ... Does dark matter carry an electric charge is the headline - which turns out to be a bit of PR. Astronomers, it is said, have produced a new model for the invisible matter that is supposed to make up most of the universe - the so called dark matter (unseen and unverified). These particular astronomers and modellers think dark matter might have an electric charge. However, this is just a 'tiny' electric charge - so they are not jumping in with both feet.

NASAs Space Engine Tested

Spaceflight is difficult. Blasting heavy cargoes and spacecraft to respectable speeds over interplanetary distances requires so much propellant to sent rockets to far away places - unless you have an engine that can generate thrust without fuel. Scientists at NASA have been building and testing the EmDrive - which is said to produce thrust simply by bouncing microwaves around inside a closed cone shaped cavity. Sounds wonderful. No fuel is required.

Brian J Ford

Sent in by Robert - an article by Brian J Ford in the magazine Spaceflight from way back in the 1960s when it cost just 4 shillings a copy - go to http://brianjford.com/wbib65.htm .... and remember the article pre-dated the EU theory or anything by mainstream on plasma. Ford foresaw the craters on the moon as having an electrical origin - but invoked static electricity. He also said there were two outstanding features which cannot be accounted for by meteorites or volcanic activity, namely the occurrence of a central peak in many of the craters (but not all of them).

Ozone munching chemicals

At https://phys.org/print445696943.html ... envrionmentalists, a somewhat blanket term but in this instance meaning CAGW enthusiasts with an agenda, still persist in the belief CFCs are destroying the ozone layer in spite of numerous studies that say it is the solar wind that disperses ozone in the upper atmosphere, are at it again - but in this instance they may be slapping themselves in the face. Apparently, they've discovered the Chinese, or a close neighbour of them, is disregarding the UN ban on the production of CFCs (that the environmentalists claim has healed the ozone hole).

Red Air Glow

The image below is of red air glow over the Atacama desert in Chile - courtesy of www.spaceweather.com (May 11th). Photographer Yuri Betelsky took the image - the air glow was so bright parts of the Milky Way were barely visible because of the intensity of the red glow. This is caused by chemical interactions in the atmosphere - via ultra violet radiation. The red air glow was floating in a band 87 km above the surface of the Earth. Betelsky has captured air glow on film on many occasions - but rarely as bright as on this occasion.

The STEVE has paid a visit to the United States. This picture was taken a few days ago ... go to www.spaceweather.com
