The Sun, November 21: Two large filament eruptions occurred (not directed toward Earth). It is cleaning itself or “shedding helicity", as @swmcintosh describes it.

Synoptic sun: Quiet. Negative coronal holes in the W, positive CHs in the E (produce fast solar wind), sector boundary between (makes Parker Spiral); no active sunspot groups in the center (earth facing); new regions in the E, potential flare/CME producer; solar cycle 26 bands

Yet another filament lift-off. East. North. South. All from the far side of the sun. Very large. Very impressive.

Multiple filament (/prominence) lift-offs, including the northern polar crown filament. The filament near the east limb ⬅️ needed two attempts to erupt.

2025-11-19 1000z – C9.9 solar flare with coronal mass ejection to the East from a new sunspot region at/behind the NE limb of the Sun. It will soon rotate into view and we'll see if it has potential for more CMEs…

Sunspot group (a.k.a. active region) 4284: 48 hrs of growth – now w/ leading + trailing spot - both showing a penumbra – some polarity mixing in its intermediate section – βγ – SDO AIA 131 Å overlay shows flaring activity – still potential to become a big flare/CME player

New sunspot group 4284 lost some of its complexity, it's simple beta east/west now, but appears to be still growing + An equatorial coronal hole is approaching the central meridian + 2 new regions near the east limb (appear to be rather simple and inactive)

A new sunspot region popped up South 6° near the central meridian today with a crazy amount of flux emergence, an unusual north-south orientation and a decent complexity already. The initial growth is faster than that of region 4274/4246 i'd say…

Fast and wide coronal mass ejection associated with an X4.0 solar flare from sunspot group 4274. There's a chance for a glancing blow November 16. It may enhance the magnetic field of the approaching stream interaction region from coronal hole 95.

Complex eruption associated with a M1.8 and X4.0 solar flare. A fast CME ('solar storm') was produced. It is heading to the solar West and will likely miss Earth.

M1.8 class solar flare + X4.0 solar flare from region 4274 with radio burst. An asymmetric full halo CME was released. It's heading NW but parts might graze earth and/or enhance the effects of the approaching stream interaction region from coronal hole 95-
