Seeing today was relatively poor but after multiple days of no activity on the disc, I was anxious to get out again. Here are some shots of the regions around AR2871.   Also a video including a most-size surge prom.  The video is ~ 35 minutes in real time, one frame every ~ 1.5 minutes.  The video is posted on astrobin.

This one is just a thumbnail from the video:https://astrob.in/full/0hsizf/0/

These two are slightly different renditions of AR2871.

Very nice despite not the best seeing. Did you process the surface and proms separately?

I had really variable seeing today, from horrible to Ok.  You did very well Robert.  The animation looks violent.

Hi-- No, in these shots the proms and surface are all part of the exposure, just manipulating the histogram after-the-fact in photoshop to enhance contrast where it is needed.

Yeah, it looked great early morning, but by the time the sun cleared the trees there were thin clouds everywhere.  I almost gave up, but decided to leave the time-lapse go while I went to get groceries and was rewarded with this little surge prom.

Nice catch on that surge prom!  I haven’t had a chance to start processing mine from this morning so will be interesting to see if I caught any activity!
