The Sun 14th April 2015 – Active Region 2321 Sunspots

Atmospheric visibility was pretty shaky today with lots of turbulence and high wispy cloud passing over so I was pleased to get this set of images in less than ideal circumstances. Active region 2321 is superb with lots of spot and pore detail and harbors enough energy for some flares. Two new sunspot groups are also rounding the eastern limb (left side of images) so it is going to get pretty crowded on the Earth facing side of the Sun.

Images taken 12.12- 13.23 (UTC+1) with Coronado PST CaK, Lunt CaK diagonal at 100mm on Vixen 115s, DMK41 camera.
