Hey all,
Lots of clouds this morning and only ok seeing, but managed to get a little bit of AR2740 and the proms around it. It seems to have thrown some lovely surge proms later, but I'm clouded out for those. This was around 0930am Eastern when I captured these. Captured in HA, WL & CaK at various scales to compare as seeing allowed. Saw a little tiny flare activity around the spot.
