A Dark Hole On The Sun

    The sun has a constantly changing surface which, at times, contains what appears to be holes.

    NASA recently released a composite image taken on October 4th by its Solar Dynamics Observatory, which shows a dark, vacant-looking patch amidst bright swirls.

    This noticeable area is called a coronal hole where gusty solar winds blow through an opening in the sun's magnetic field.

    The space appears relatively dark because, in contrast with the packed, intense hot spots that surround it, it is an area with a lower density of particles and, therefore, a lower temperature.

    Its wind currents tend to carry particles out of the sun at speeds of up to 500 miles an hour and can affect the weather in space around Earth.

    With this particular system, Spaceweather.com estimates that this plasma stream could enter Earth's magnetic field around October 8th which could lead to auroras at high latitudes.

    The likelihood of geomagnetic storms may increase as a result, possibly interfering with satellites, spacecraft, and other sensitive devices deployed around Earth's atmosphere.

    Uh oh. Climate change. The only answer is higher taxes and more federal regulation. [sarc2]
    That'll close up the dark spot in the sun.

    Back around 2005 there was one of these dark spots on the sun.
    I was stationed in Japan at the time and just happened to look up at the sun with a #9 shade glass in my welding helmet, and could see it. Only other time it could be seen was at sun set.
    If I remember correctly it was visible for 3 to 5 days as it moved across the surface of the sun.
    I'm sure it wasn't the first and won't be the last one.

    These are called "Sun Spots"....

    I don't think they are usually that clearly visible with minimal to no equipment for that long.

    We need to load a rocket with antifas, Rosie, Fat Mikey and Algore, shoot 'em into that solar "hole".

    The coronal hole is pretty much gone for now, but we do have a couple of sun spots that are of interest, and one of them is growing at an amazing rate. M class flare is possible which may disrupt HF coms and make for some interesting auroras. Now if an X class flare or CME pops out... .

    My belief :cautious: is that all that solar activity is caused by all the solar systems on Earth sucking up exorbitant amounts of energy from the sun. It is Man Caused....:censored: :coffee:

    I wonder if it is possible to "Poison" the Sun, that way....
    Although I have LONG Advocated using a Nuclear Powered RailGun to SHOOT all our Nuclear Waste into the Sun, for disposal....

    How about not creating the nuclear waste to begin with??

    That's one of the reasons not to use the cloud for critical data. Some people may find their network unavailable.
