Eruption/CME 2025-11-19 2230 UTC from the vicinity of an active region behind the SE limb (left) makes the field lines of the northern active region wiggle (top right).

Active Sun Type II Radio Burst registered 2025-11-20 1459-1503 UTC – estimated speed 1196 km/s – Likely from a far side eruption to the south visible in GOES SUVI 195 running difference

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. The Sun in GOES SUVI 304Å + 304Å/195Å/284Å running difference

5 days of the Sun: Leaving sunspot group 4274, emerging 4284 (center), filament eruptions, negatively polarised coronal holes in the W➡️, positively p. CHs in the E⬅️, new flaring region in the NE is rotating into view SDO AIA 211Å BD, 193Å BD, 171Å, 211Å, 335Å

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… (SDO AIA 304/171/193BD/211BD Composite)

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…

West limb of the Sun: magnetic loops, dancing filaments, M3.1 flare, brightening, post-eruptive arcades, coronal rain

Bye bye crazy sunspot group 4274. Will we meet again in 14 days?

First filament says good bye and leaves, second filament likes the idea and wants to leave, too. Sun says no.

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.

Strong X4.0 solar flare near the west limb of the Sun with flare ribbons, post-eruptive arcades and opening field lines.

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- Waiting for model runs

Sudden IMF Enhancement 18:53 UTC – likely the shockwave of the anticipated CME. The dynamic pressure pulse may trigger a substorm/storm soon, for an extended mid lat aurora show we need negative Bz. It's too early to say how it will develop.

Another Earth directed coronal mass ejection after an X1.2 flare eruption from sunspot region 4274. Arrival early on November 12 + strong geomagnetic storm expected.

Decent coronal wave and some dimming after an X1.2 flare from sunspot region 4274

Another animation of the beautiful and complex solar eruptive event today (filament eruption + X flare; SDO AIA 171, 211 Å)

24 hours of region 4274 – a lot of flux emergence in its intermediate section and more magnetic shear again

X1.7 class solar flare from sunspot region 4274 – R3 radio blackout - Type II radio sweep 804 km/s – Broadband radio burst - Large EUV wave spreading NE and SW - Likely associated with an earth-directed full halo CME - a filament eruption occurred before

24 hours of region 4274 – it shows both: signs of decay and consolidation but also some new flux emergence in its intermediate section.

Six days of solar activity in SDO AIA 131, 171, 211 Å (solar flares, magnetic loops, coronal plasma)

The large rotating trailing spot of region 4274 looks like a drain that sucks in the flux above it and helps it untangle itself. (SDO AIA 212 Å + SDO HMI Continuum, 2 min cadence, 22 hours)

Sunspot region 4274 update: The leading section is showing decay, the large trailing spot rotates and looks like a cyclone.
