AR2824 in High Res HA, WL | Mod Res HA, CaK | May 25th 2021

[MalVeauX]

Hey all,

Finally had a day off work, seeing was pretty good this morning. AR2824 is such an active region, popping flares every day, and has a lovely surrounding area in the chromosphere with lots of mottling and interesting plage and filament tangles. The extent of the AR is really apparent in Calcium showing the bright faculae. The AR is being lead by an interesting new flux disturbance region that will round the limb soon (which may produce a really interesting view on the limb if it persists, such as potentially some loops!).
