The 2 small flares on  the NEE limb of the solar surface have evolved into 2 very active regions and named AR12627 and AR12628. Meanwhile, AR12625 and AR12626 remain similar to the previous day as huge patches of plages with a few scattered flares.

During the 5 hour-observation session, both AR12627 and AR12628 show active eruptions, throwing large amount of material into the corona. These eruptions continue when observation ended shortly before 5 pm. Images are 800x800 crops from original.

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.
