After being forced out of the roof of my office since 2015 December, I finally get back to setup my solar equipment last week.
The Sun is relatively quiet these days.
This small active region AR12557 seems to be very active, showing much flare activities and a minor mass ejection into the corona from 08:04 - 08:30 (HKT).

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.
