    Sunspot and Flare Alert

    The Sun has gotten a bit more active of late.  A sunspot 1024 (Active Region 11024) and flare (in H-alpha light) are currently visible.

    I observed the two events through my Coronado PST and an 8-24mm Tele Vue zoom eyepiece earlier this afternoon.

    Thanks, Dave!

    For about a week, Radio JOVE sites have been tracking some anomalous solar activity that indicated small flare events. I've only been able to observe on one day in h-alpha and that was at the same time Spaceweather.com was reporting that Monday's small spot was dissipating. When I observed it in Ha, it was actively flaring and quite bright. It was gone from that wavelength's view the next day.

    I put another post on this today,

    It's looking very good in Wight Light now (around 29 seperate umbrae small to medium sized) and plenty of prenumbra around the larger spots.

    Non too shoddy in H-alpha neither, plenty of activity and changing over a number of minutes,

    I had another look at AR 11024 on Sunday afternoon with my PST under better conditions.  The flare region was quite obvious.
