Looks a very promising region for the coming week

Rubbish iPhone picture through the haze today, but it shows the third spot clearly. Should be really nice when it comes fully into the disk.

Hello. Similar view that I had about 4.30 this afternoon. Seeing poor but the group seems very promising for this coming week.

3 jpgs for size - 1208, 1229 & 1303 UT.  The party got started between 1208 & 1229 UT I guess?

 

Wow - nice shots!  
Actually, the prom I saw was later and much larger - even bigger than in my crappy sketch. But it was very faint. I needed to black out all light to see it well. Unfortunately had a high layer of cloud today so viewing not great.

Developing nicely. Had some ok views through the haze this morning. Need some clear skies soon!

Not sure if this video will work, but it’s a timelapse of the last three days smartphone images showing ARs 12993 and 12994 rotating to view. I’ve posted the individual frames incase the video doesn’t work.

Another decent sized spot has appeared around the limb overnight. The other spots have really quite complex umbral regions now. Nice!

Yeah Stu, has really complex magnetic fields and fizzing with flares this morning in both HA and CaK.

Fantastic today, just a screenshot for now. Dentist appointment in a few hours, ouch.

AR has been crackling with activity today in Ha. New areas brightening suddenly, then fading back. Seeing not great, but even at 40x-50x it’s a stunning sight.
