After a dreadful week of weather (particularly yesterday!!) finally the Sun came out today surrounded by beautiful blue sky with no clouds in sight...wow. That said, the seeing conditions were below average for my location with high frequency shimmering on closer views making sharp images somewhat of a challenge.
Anyhow, here are my FDs and some closeup views of the main features: AR12886, a beautiful surge prom from something coming around the SE limb and a very fine pair of proms including a nice looping prom.

Unfortunately my Ha FD mosaic has a slight light band down the centre. The pressure tuner needed a bit of a tweak.
