30 year cooling

At www.ncgt.org/newsletter.php ... click on the March issue at the top and scroll down to page 98. RT Cahill of Flinders University in Adelaide published the original story in Progress in Physics 10: issue 4 (Oct 2014, page 236-242) and it was reproduced, in part, at the NCGT Journal. It claims space speed fluctuations cause solar flares. The direction and magnitude of the space flow has been detected from numerous different experimental techniques and is close to the normal to the plane of the ecliptic.

Southern Lights

  at http://phys.org/print347186673.html ... a nice image of the Southern Lights - aurorae near the South Pole. These have recently been visible from Australia but are apparently a rare occurrence as far north as Brisbane - more usually restricted to Tasmania.

geomagnetic events

At http://chiefio.wordpress.com/2015/03/27/geomagnetism-jerk-excursion-rpi-... ... we have some interesting information where science is at a boundary of knowledge and is in the process of changing its mind. The settled science, it seems, has not settled too well (an it all comes in the indomitable style of EM Smith, computer whizz kid).

fulgarites

It is a well known theory that lightning causes fulgarites but an open access paper at http://dx.doi.org/10.1130/G36255.1 ... for the Geological Society of America, claims volcanic lightning can also produce glass from volcanic ash.

At http://phys.org/print344596072.html ... some nice close up images of the surface of Comet Churyumov-Gerasimenko taken on the 14th February.
 

SIS Spring Meeting

Bob Johnson's talk at the SIS Spring Meeting in Watford will be . The Variability of the Sun and the Effects on Earth. In other words, what effects do CMEs have on the Earth system and the inhabitants on the surface.

a differentiated core

At https://tallbloke.wordpress.com/2015/02/10/earths-core-has-a-differentia... ... seismic soundings are said to have provided new information on the nature of Earth's core. Chinese and US scientists collaborated in the project - see also http://news.illinois.edu/news/15/0109.innercore_XiaodongSong.html and www.eurekalert.org/pub_releases/2015-01/ci-mli012215.php and www.principiea-scientific.org/new-study-invalidates-kirchhofa-s-law-of-t.... Tall Bloke asks, what is the implication for geomagnetism in history.

Stratospheric Warming bring Snow to Somewhere near You

Tim Cullen at http://malagabay.wordpress.com/2014/12/13/a-christmas-recipe-for-snow/ ... makes the point the Sudden Stratospheric Warming events show that the polar vortex is an electro magnetic phenomenon in that it can be slowed down or can even reverse its direction - much in the same way that electro magnetic factors as a result of CMEs striking the atmosphere can switch or change the position of the Jet Stream.

Lockheed Fusion

The Lockheed Fusion project is going well they claim - go to https://cosmosmagazine.com ... (October 24th 2014) are working on a fusion reactor that could fit on the back of a truck and power a large town. Fusion is a nuclear reaction to which small nuclei are melded together to make larger ones - the opposite of what happens in the fission reaction of the normal nuclear power station. Both methods release lots of energy but fusion does not produce harmful and long lasting radioactive waste. The fuel on which it feeds, heavy hydrogens, is relatively cheap and commonly available.

how sun spots may erupt

At www.q-mag.org/understanding-and-forecasting-solar-eruptions.html ... Anne Marie de Grazia has translated into English some French research in which they have followed the evolution of the solar magnetic field in a zone of eruptive behaviour. Their calculations show the formation of a magnetic cord which emerges from inside the Sun, becomes associated with a subsequent sun spot. They show the structure plays an important role in triggering CMEs - eruptions.

SIS Autumn Meeting 2014

The SIS 2014 Autumn Meeting took place on October 25th, staged at the Quaker Meeting House in Watford, a fine venue. The Quakers, and various other non-conformist denominations, including the first Baptist groups and the Congregationalists, were especially strong in the Chilterns and adjacent regions. Watford sits on the cusp of the London Basin, on the edge of the Chilterns. No doubt it had a role in the process of keeping non-conformism alive during the reign of Charles II when rivals to the Anglican Church were discouraged.
