AR2736 – H-alpha images – March 22, 2019

Scroll down to content

My first H-alpha solar image of 2019, and a superb subject: a very fast growing sunspot group, designated AR2736. A source of C-class flares. And a joy to observe the fast changing chromosphere inside this group. a lot of Ellerman bombs are also detectable in the image.

Equip: 150mm achromat, Quark Chromosphere, ASI 174MM. Seeing 4-6/10.
