Sunspot AR 2673 is getting closer to the solar limb. It is very impressive still, with a very complex shape and strong magnetic field. Its a “must see” group!

Equip: 200mm F/5 Newton telescope, full aperture frontal filter, ASI 174MM and Baader Red filter. Seeing 5/10.

Only a couple of hours after the above shots were acquired, this group unleashed an X-9 class flare. I was able to observe the aftermath after two more hours:
