Prominence Flames
Activity on the sun seems to be increasing daily. I took this single-exposure image this afternoon; the sun's disk is deliberately overexposed to enhance the detail in the prominences. The air temperature was 101.4 F and the heat index over 104. The laptop kept shutting down due to overheating. Seeing was much better than of late, so there are some compensations to the heat!
