Those regions on the farside of the sun are producing full halo CMEs and look large on farside imagery. They will be back next week

STRONG SOLAR ACTIVITY RESUMES: The quiet has broken. Today sunspot 3936 produced a strong X1-class solar flare (0717 UT) along with a series of M-class flares peaking at M7 (1509 UT). As a result of these explosions, at least one CME is heading for Earth, and a NASA model shows it reaching Earth late on Dec. 31st. " solarham.com "A partial halo CME observed leaving the Sun earlier on Sunday (Dec 29) is predicted to sweep past Earth by New Years Eve (Dec 31). A strong (G3) geomagnetic storm watch was officially added by NOAA/SWPC for that date. Contrary to other sources, the CME is not related to the X-Flare and was the result of an eruption in the vicinity of AR 3939 in the southeast quadrant. Perhaps some aurora to ring in the new year should local weather and viewing conditions allow." Late Dec 31 would be 24z or 6pm central time. It would be great to see the Northern Lights before the fireworks! |
What does that mean?Tight delta sunspot on region 3981 in the southern middle spot with a lot of other spots getting strong magnetic shear, oh boy View attachment 167580View attachment 167581
Sorta similar to a radar couplet, lots of magnetic shear packed in one tight spot, delta sunspots are volatile and can produce significant solar flares and associated coronal mass ejections. The tighter the blue and red is, the more likely you got a delta sunspot with 2 or more spots within a penumbra. Think of a delta as a constant aggravation with 2 opposing magnetic fields pushing up on each other creating instability and increases the odds for something to go boomWhat does that mean?
