Observing or imaging the Sun is DANGEROUS unless you use specialist equipment. NEVER risk your eyes.
Unusually for the Northwest, it was sunny today again!
The Sun seems to be getting more active with some M-class flares recently. Took the opportunity to try to get close-ups of some active sunspots such as AR 2149.
