A small transient coronal hole opened up west of region 4294/ex4281. This could lead to an acceleration of coronal mass ejections, as fast solar wind may escape from this coronal hole.

The vicinity of sunspot region 4294 (ex 4281) is a large and complex magnetic mess. The area behind it may be given a different number.

NE limb eruption, likely from the vicinity of region ex 4274 (ex 4246) with type II radio burst, estimated speed 731 km/s

A very active sun in both hemispheres – this is unusual for this solar cycle.

Eruptive powerful M5.9 solar flare from sunspot region ex 4281 (new number possibly 4294). A type II radio emission was detected – estimated speed 828 km/s.
The possible associated coronal mass ejection won't be earth-directed (i assume) but now we know ex 4281 can produce CMEs.

I just can't get enough of watching these coronal magnetic loops. Majestic and mesmerizing.
(We are likely seeing old region 4281 approaching the southeastern limb of the Sun)

Old acquaintances in the eastern part of the Sun: The 'butterfly' coronal hole and near the SE limb old sunspot group 4281. The latter is leading to increased flare activity. Let's see if it can also produce CMEs.

Close up of an eruption from the far side of the Sun behind the NE limb (not facing Earth) - we see how material from the upper corona was initially pushed away.

Eruption on the far side of the Sun – a CME producing active region is coming closer to the East limb. Is it old 4274 or a new one?

A large complex of + polarised coronal holes will dominate Earth's space weather in the next few days.
Fast solar wind > 700 km/s from November 25 on (?)
Interaction regions, small filament eruptions and a newly emerged sunspot group inside the complex ☞ G1 MINOR STORM likely
