Details:
The flare in AR3780 imaged today: just a 10-minute worth of imaging, showing a strange evolving flare (look at the twister-like event in the main sunspot's penumbra, towards right). Also, white-light/h alpha light comparison, showing the sunspot being active in both wavelengths.
150mm refractor for h alpha, 200mm Newtonian for white light.
