CMEs

At https://wattsupwiththat.com/2017/02/01/still-far-more-worrisome-than-glo... ... just noticed this one after visiting Anthony Watts place. Solar physicist Leif Svalgaard informed Anthony of the possibility of a Carrington style event (a large CME in 1859). It could bring down the electricity grid system and damage satellites etc (the same thing that regularly pops up when this sort of event is mentioned and surprisingly given short shrift by some of the commenters).

plasma behaviour

At www.thunderbolts.info/wp/2017/01/27/at-any-scale/ ... we have further clarification on plasma behaviour which is useful as we lead up to our speaker meeting in April which will be addressed by Bob Johnson. This time the issue is the so called 'fast radio bursts' - fast release of energy that lasts just a few milliseconds. Obviously, this was an unknown until the advent of recent instruments. Blink and you would miss them.

Earth's Magnetic Field

This link was sent in by a member of SIS - http://crev.info/2017/01/earths-magnetic-field-3/ .... which concerns a New Scientist piece by Marcus Woo on the magnetic field. It is useful as it illustrates how some people may reinterpret what other people say - and no doubt I do this all the time as well. What Woo appears to do is point out anomalies concerning earth's magnetic field - and most science journalists would not bother to mention anomalies so Woo is to be congratulated.

Strange Earth

    January 6th in northern Ontario, weird light show. Go to www.livescience.com/57482-light-pillars-photo-ontario.html ... and for some weird geological pictures there is a video show at www.msn.com/en-us/travel/tripideas/californias-geological-phenomena-that...

liquid iron jet stream

A liquid iron plume streaming from Earth's core has been likened to an internal jet stream. It is claimed that it is actually accelerating which is interesting as the magnetic north pole is behaving oddly. The European Space Agency's Swarm satellite system is providing sharp x-ray images of the core according to Phil Livermore of the University of Leeds (the findings are published in the December issue of Nature Geoscience). The new information is helping scientists to understand the earth's magnetic field.

Fusion energy

At http://phys.org/print401535144.html ... the generation of fusion energy utilises the fusion reaction that occurs inside a high temperature plasma. To do that plasma is confined in a magnetic field, see ...

   ... and computer simulation is being used to understand the behaviour of plasma in the quest to develop commercial fusion energy. Research is ongoing.

Atmospheric Thermostat

At https://wattsupwiththat.com/2016/12/15/agu16-researchers-dial-in-to-ther... ... yes, a thermostat in the atmosphere that works like a thermostat in a car engine. It dramatically cools the air after it has bas been superheated by the solar wind (CME events). Solar flares zooming towards the earth create shock waves, we are told, similar to sonic booms, and heat the upper layers of the atmosphere.

Mars magnetism

At http://phys.org/print397736203.html ... Mars has numerous pockets of magnetism locked up in its crust - but scientists assure us that Mars has no inner dynamo, the hypothetical source of magnetism on Earth. How does it get there? Even more mysterious is the claim that these scattered pockets of magnetism actually influence the atmosphere of Mars. How do they do that?

Ping

At www.dailygalaxy.com/my_weblog/2016/11/mysterious-pinging-sound-detected-... ... wildlife has disappeared - such as bowhead whales, bearded and ringed seals etc. Instead, a strange noise has been heard coming from the sea floor. What is going on?

Mount St Helens

   At www.dailygalaxy.com/my_weblog/2016/11/mount-st-helens-is-getting-weirder... ... geologists have been trying to understand how Mount St Helens works. It is a volcano of the Cascade Arc and one of a string of eruptive volcanoes that run parallel to the hypothetical subduction zone between tow major plates between British Columbia and California.
