After what seems like weeks of grey and dreary weather, the high pressure that is sat over the UK at the moment finally gave way to properly clear blue skies. I was keen to image under excellent transparency, even if seeing was poor with boiling skies. There was plenty going on the solar disk with several large active regions as can be seen. Though, unusually, today the sun was remarably devoid of prominences. All of the active regions could be seen to be showing minor low level flaring. This shot was taken with Coronado DS40 etalons on a 420mm fl ota.
