For you sun watchers out there, interesting space weather on our Logos - Moonfox - 02-14-2019
Hello all! Happy Valentines Day <3
I am a space nerd and I am also a weather nerd so of course I also have to follow space weather. ;-) Mars Opportunity Rover mission came to an end yesterday, and this coming full moon on the 19th is going to be a Super Moon. Hopefully we'll see some of it, but we have had terrible cloud cover lately.
This Thursday has brought us "Big Activity On The Sun" according to space weather.com. Here is a link to a video: http://spaceweather.com/images2019/14feb19/20190214152624_512_aia_0304.mp4?PHPSESSID=bsgjihijnv7en0233sapbc9ci5
Quote:This is called a "hedgerow prominence." Hot glowing plasma inside the structure is held aloft by unstable magnetic fields. If the magnetic support collapses, plasma can fall back to the solar surface, exploding in a Hyder flare--a type of solar flare that can occur with no underlying sunspot.
NASA and Japanese space telescopes have taken high resolution images of similar prominences and seen some amazing things such as (1) tadpole-shaped plumes that float up from the base of the prominence; (2) narrow streams of plasma that descend from the top like waterfalls; and (3) swirls and vortices that resemble van Gogh's Starry Night.
Here is the one for today:
Quote:THE SOLAR WIND IS HERE: Earth's polar magnetic field is unsettled today, Feb. 14th, as our planet passes through a stream of solar wind blowing faster than 500 km/s. The gaseous material is coming from a southern hole in the sun's atmosphere.
So for all of you who were talking about the poles and what affects them, the solar wind affects Earth's polar magnetic fields. This can have a destablizing effect, on top of what we are seeing with the poles changing places, the north pole seemingly headed for Russia.
