Meanwhile on our nearest Star as seen to me this morning:
Giant sunspot AR2781 is crackling with solar flares. The strongest so far, a C7-class explosion at 0022 UT on Nov. 5th, lit up the sunspot's magnetic canopy
X-rays and UV radiation from the flare ionized the top of Earth's atmosphere, causing a brief low-frequency radio blackout over the Pacific Ocean and Australia. Mariners and ham radio operators in the region might have noticed signals fading, especially at frequencies below 10 MHz.
AR2781 has nearly doubled in size since yesterday. With a primary dark core more than 3 times wider than Earth, the sunspot is an easy target for amateur solar telescopes. (Spaceweather.com) My photos
