thermosphere gusting

William Thompson forwarded this link - http://eos.org/research-spotlights/scientists-detect-wisps-of-wind-in-space ... on a paper in the Journal of Geophysical Research: Space Physics (January 2016). It is about the way the aurora seems to distort weather at thermospheric altitudes at latitudes (polar and near polar). Aurorae stir up storms at an altitude of 250km - but where does the wind blow? The thermosphere is on the edge of space. It begins at 85km altitude and extends to 1000km high.

zodiacal lights

Rens van der Sluijs continues his posts on people in the past that have mentioned electricity in space - see www.thunderbolts.info/wp/2016/01/11/current-models-of-the-sun-a-charged-... ... followed by part 3 and 4

Comets and the Sun

Comet Holmes was a bit of a damp squib in 2014. It was an eagerly awaited visit to the inner solar system as in 2007 it had been a bright and dazzling object visible from Earth without the need of binoculars. Subsequently, a lot of people got interested in Holmes - was there going to be a repeat show. It seems the solar wind didn't provide the fireworks to make the coma glow so radiantly.

Faraday on the Aether

Interesting letter by Faraday to an aquaintance in 1854 - go to https://tallbloke.wordpress.com/2016/01/07/michael-faraday-thoughts-on-r... .... which must be one of the earliest lines of enquiry on electricity in space. He was the author of 'Experimental Researches in Electricity' published in 1846.

Wal on Song

At https://www.youtube.com/watch?v=gr-rdSTg-Fk ... we have a video of Wal Thornhill, '2015; a year of surprises' which amounts to the EU take on ESAs Rosetta mission and NASAs New Horizons mission to Pluto, and so on. Good one.

See also https://www.youtube.com/watch?v=VaTGsPr1r54 ... which is the  EU take on magnetic reconnection, the mainstream solar physics view of plasma energy transfer.

big one coming

A big sunspot, AR2473, is directly facing Earth at the moment. Will it explode - or wait until we are out of alignment?

magnetic reconnection

At www.sciencedaily.com/releases/2015/12/151218161458.htm ... NASAs MMS mission (Magnetospheric Multiscale) is looking at magnetic effects caused by the solar wind. The explosive realignment of magnetic fields is known as magnetic reconnection and is thought to take place at the boundaries of Earth's magnetic bubble. Magnetic reconnection, it is alleged, can connect Earth's magnetic field to the interplanetary magnetic field as carried by the solar wind and coronal mass ejection events (CMEs).

winter warmer

Winter Warmers usually come in the shape of bottles of strong ale or mulled wine or even in warm jugs of cider laced with ginger, cinnamon and cloves, but in this instance we may have another kind of winter warmer, a burst of solar energy that struck the Earth on the 19th December. The insinuation here is that big outflows of plasma from the Sun can add a lot of energy in the form of heat into the Earth system - which it therefore has to quickly dissipate to get back to ambience. Hence, the outflow of heat from the overheated tropics into NW Europe. Can it really be that simple?

radiation block

Joy sent in a link to https://eos.org/articles/human-radio-transmissions-create-barrier-to-kil... ... and at first I thought it was a spoof, then realised they were being serious. The claim is that inter-action between radio waves from human transmissions on the surface of the Earth and the Van Allen radiation belts creates a bubble around the Earth that high energy electrons cannot penetrate. Very low frequency radio transmissions from Earth may be involved - and the emphasis here might be on the 'may be'.
