No, tho would like to get an astronomical telescope and camera. Sort of interested, following a solar physicist, Dr Keith Strong, @drkstrong, on Twitter.

He shows some nice movies of the sun using various filters etc. Sun a bit quiet at the moment but we should see some fireworks again soon.

The sun affects us critters down here—a nice flare or CME will cook our computers nicely Grin

THE SUN TODAY: 1) SSN up to 120. 2) No significant flares in the last day. X-ray background at B7 3) helioseismology shows two huge sunspot regions on the far side of the Sun 4) Lots of tiny sunspot appearing especially in the south. Will they amount to anything? Large spot in NE

CME WATCH - 2023.02.06: Just watch the SE/E limb (bottom left) it has almost continuous eruptions and not puny ones either. No sign of anything significant on the near side so this must be regions behind the limb. Hope they keep going when they rotate onto our side of the Sun.

THE SUN TODAY: 1) SSN at 120. 2) A lone C8 flare but a huge number of small C flares (see previous tweet) 3) A substantial region seems to be behind the SE limb according to STEREO. 4) Many new NOAA numbered regions. Particularly rapid growth in regions AR3213 and 3214. 5) 5 CMEs

(no interesting video)

Activity picking up again after a quiet spell.

SPECTACULAR M1 FLARE: It has been over a week since we had an M flare but this one was worth waiting for. It came from behind the east limb of the Sun (so was much larger than M1). Note its size compared to our puny Earth (inset). More likely to come as this comes over the E limb

MASSIVE flare, spectacular video!
