An unusual coronal hole appeared on the sun this week, as seen in these images from NOAA's GOES-19 Solar Ultraviolet Imager. Since this feature was so persistent, it will be interesting to see if it is still there when this region rotates around into view again.

  1. – first pic: sufficiently fascinating. even worth a “hmm”  
    – second pic: terrifying seeing it “aimed” directly at us

  2. Are we entirely sure that this isn’t a cosmic sized spot light for space Commisioner Gordon to summon Butterflyman?

  3. I wonder how deep it is? Is this the first time we have been able to see this far into the sun?
