2018 January 22 Sun - strong flare from AR12696
While the sky is covered by thick fog/smog, seeing is in general good despite a very poor transparency.
AR12696 has been relatively quiet in the past few days up to about 02:32 UTC this morning when the last batch of my whole disc images are capture before changing my optical setup for clsoe-up. When I start to adjust the focus after adding the 4X telecentric lens, the flare from AR12696 is in full. Observation has to stop at about 03:11 UTC due to another appointment. When I come back after lunch and check the image from Udaipur, India, the flare event is already over.
Telescope: AP Starfire EDT 155 mm f/9.
stopped to 50 mm (f/28) for disc images, with 4X telecentric lens (f/36) for closeups
filter: Solar Spectrum SO1.5/0.3A with CERF prefilter
Camera: Imperx 4M15
