AR11856 and AR11857 continue to develop in the last 24 hours into large and very active regions.  AR11856 gives a spectacular eruption of flares starting around 11:50.
Here are just a few snapshots of this eruption.  The full event will be posted here when I can find time to process them.

Telescope: AP Starfire EDT 155 mm f/9.
stopped to 50 mm for disc images, with 4X telecentric lens (f/36) for closeups
filter: Solar Spectrum SO1.5/0.3A with CERF prefilter
Camera: Imperx 4M15
North is up, and east to the left
