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'.

magnetic storm on comet

  Geomagnetic storms as a result of the solar wind buffeting the atmosphere are well known - but here we have an image of a geomagnetic storm striking the sinuous ion tail of Comet Catalina. The blobs of plasma are circled. See www.spaceweather.com

dendritic patterns

The ridges can be clearly picked out. Along the Italian coast such features are said to be common. The author of the piece speculates these were formed by thunderbolt strikes (lightning) which sent massive shockwaves ripping through the Italian countryside.

earthquake fire

Paul Devereux wrote a couple of books back in the 1980s on earthquake lights and electro-magnetic discharges associated with earthquakes which had a New Age slant but was an attempt to nudge people out of their inertia in respect of fringe science. He went on to investigate pyschology, psychodelia, and harmonic phenomena (stones that ring like a bell etc). As such, Devereux will always be a little on the sidelines - as his work on earthquake lights proved to be.

magnetic stars

At http://phys.org/print364733015.html ... astronomers have discovered stars are strongly magnetised. Using a technique known as astroseismology, where sound waves generated by turbulence at the surface of stars is used to probe their inner properties.

rumbles and plasma

At https://tallbloke.wordpress.com/2015/10/07/resonant-rumblings-inside-sat... ... unusual ripples in Saturn's rings are part of a mysterious rumble. The rings are full of activity, including waves that ricochet outward in spiral patterns, possibly as a result of the gravitational pull of Saturn (although Birkeland Currents might be inferred). Saturn has 62 moons and may all have an affect on the ring system.

Lost World of Saturnian Cosmology

I don't know what you make of this site but at http://saturniancosmology.org/other.php ... the web site host takes a swipe at alternative catastrophist theories, all the while maintaining it is credible to think in terms of a Saturnian scenario. Keeping a straight face is the secret I suppose.

big bar magnet

Interesting post at http://phys.org/print361784158.html ... Earth is like a big bar magnet - and its attract and repulse properties. A Swedish space balloon project is in progress. Space is big and the density of particles is small (electrons and protons) and they can move along field lines without bumping into each other. During geomagnetic storms the particles get pushed further down the field line, crowding each other and getting closer to the surface of the Earth. Then, they start to interact with the upper atmosphere and some of the particles disappear. The search is on.
