Solar surface activity at high res June 19 2018 280mm aperture.

Post by Valery »

Hi here,


Today was a good transparency sunny day with no any single cloud on the sky. The sky was
really blue with a very fresh air.

Fortunately the seeing also was good when it calms.


Here are two major active areas on todays moderately active sun. The AR12713 and emergency flux AR12714.


Telescopes used - C11 280mm F/10 SCT equipped with the ARIES 295mm full aperture DERF filter with new

coating version - three bands (CaK+H, H-a and G-band).


You can see a very fine structure in both areas, but I especially like the delicate structures west from the AR12714.


Comments are welcome.
