AR2672 and AR2671 -- White Light and Ha

It's nice to see some activity on the sun--especially after this week's eclipse (I will have a longer post on that later)!

AR2672 and AR2671 have a slight chance (around 15%) of producing M-Class flares. None were visible in Ha when I took the image. Here is the white light image, taken with my 90mm Mak and DS2.3+. AR2672 is towards the center of the disk, AR2671 is at the edge. All images were processed in Autostakkert with wavelets in Registax 6.


Here is the Ha image, which shows some interesting detail around AR2672, as well as some dark, filamentary material. The uneven illumination is due to the etalons in the PST-DS:
