Details:
Timelapse shot 2 days ago, about 600x real time. The activity in 4143 seemed ordinary, but little I knew that the big filament attached to the left (off screen) was undergoing a spectacular partial explosion (as featured on Spaceweather homepage on same day). Apart this, I tried to elaborate the images with less contrast in the main sunspot to catch the umbral flashes waves that David Wilson captured the same day, but it appears I don't have enough resolution. Lunt60HA, Neptune-M.
