First opportunity i've had in over a week to image the sun, and today this was in less than ideal conditions. AR11504 has been crackling with flares over the past couple of days, but now as gets closer to the limb is slowly decaying, possibly showing the first signs of lightbridge formation. Sadly at this stage the sun is pretty blank other than this active region. This was taken with the 100mm SS @ f16, DMK31.
