Details:
The sun showed many active regions today. I imaged AR3373 during the morning hours, from 09.00 to 11.54 UTC. Small flare regions were very prominent at around 10.59. The first exposure is with the Ha filter OFF. The rest of the sequence is with the Quark filter ON.
115mm APO, Baader ERF, Quark-Chromosphere, ASI183MM.
