Space Lightning

At www.spaceweather.com (August 16th) (see menu on LH side of web page) ...      space lightning over China, August 13th, photographed by Phebe Pan. He was hoping to get a shot of a Perseid meteor - but got this instead, a spectacular bolt of lightning in space. It was ejected from the top of a thunder cloud, from a position on top of a mountain. Phebe Pan said  it looked lie a tree with branches and grew up very fast.

Hawaii Petroglyphs

   Looks like the squatting man image has turned up on a beach in Hawaii. At http://phys.org/print390114735.html ... the figure was etched into sandstone rock. The comments to the article are interesting in that one of them hastens to point out the connection with Anthony Perrat's plasmoids (as in his talk to SIS, recently re-aired at the 2016 spring AGM meeting).

Green Magic

For three days the earth has been passing through a fast moving stream of solar wind. The result is this ...

Sun awakes

At www.spaceweather.com (July 5th 2016) we are told, unlike Earth which has auroras in response to solar activity, Jupiter makes its own auroras, in part from the gaseous exhaust of Io's volcanoes. Are they about to learn differently? Be that as may but on the same day a magnetic canyon shaped hole has opened up in the atmosphere of the Sun. Suddenly it isn't so quiet. It stretches more than 700,000 km end to end, a coronal hole where magnetic fields are peeled back to allow plasma to escape. A plume or stream of plasma will reache the Earth on July 8th or 9th.

Elves

  .. a Doughnut of light was seen over Colorado on June 8th, an enormous ring of light near the edge of space. Amateur astronomer Thomas Ashcraft photgraphed the doughnutusing a low light video camera.It lasted just a moment in time and was about 300km in width. This is what is known as an ELVE (Emissions of Light and Very Low Frequency Perturbations). These are due to Electromagnetic pulse sources - or that is the explanation.

Earth's magnetic field

At http://phys.org/print384004404.html ... earth's magnetic field deflects solar radiation and allows life to thrive (or that is the theory). It is also supposed the core is made of iron and this generates the magnetic field. The argument in the past has been when in the history of the Earth the magnetic field began, the overriding mainstream view being that it was not terribly old (far from four billion years ago).

Bumblebees

I love bumblebees, especialy in the spring, hovering around early flowers and blossoms. At www.smithsonianmag.com/smart-news/bumblebees-detect-flowers-electric-buz... ... it seems flowers generate a weak electric field and bumblebees sense the electric buzz. The secret is in their fuzz (tiny hairs that act like antennae).

Sprites

The image below comes from www.spaceweather.com an excellent web site currently also doing noctilucent clouds with some nice images too.

Different interpretations

I was struck by how different people interpret the same image after reading the latest offering from www.thunderbolts.info/wp/2016/04/04/divine-colors/ ... Michael Armstrong sees the gods of old as planetary in origin. Others might see them differently. When it comes to colours such as blue and black he thinks in terms of Saturn expelling dust as dark as soot. He then informs his readers that Kala was one of the names applied to Saturn - a planet. Rather than black Kala was actually dark blue in hue, he tells us. The same colour was associated with Shiva.

lightning research

At http://phys.org/print375969776.html ... the subject title is, 'what causes lightning?' - and it begins by saying it is well known that lightning is an electric current, a powerful burst of charge that flows within clouds and between a cloud and the ground. However, scientists don't fully understand how the initial spark forms - and still don't. What the researchers found is that lightning sparks not upwards (neccessarily) but downwards. How the clouds get the energy to spark such a powerful burst of electricity remains elusive.
