June 30, 2014: Quick H-alpha look in the morning

[michael.h.f.wilkinson]

Just managed a quick peek in H-alpha. A big prom was visible on the western limb, some smaller stuff to the east. The large filament near centre disk yesterday is still going strong, slowly moving westwards, and AR 2104 is developing beautifully, with a large arcing filament south and west of the main sunspots. North of that, there is a lot of activity near the limb as well. Hope to get a longer spell later today.

the prom on the western limb is still going strong, some subtle changes over the past hour, the ones to the east seem to have stayed pretty much the same as has the one to the north. AR2104 looked excellent last night and you say is developing well, will be imaging that soon.

love being off work when its sunny!

What is AR2104, please?

What is AR2104, please?

AR 2104 stands for Active Region 2104. 2104 is just a number given to the new active region southwards on the eastern limb (now well clear of it, actually)

Thanks, Michael.

If you can find the time I'd love any input in reply to my post, Some Sol. I'm eager to learn.
