A G1 geomagnetic storm is in progress with some aurora being reported at high-latitudes. This is being caused by the fast solar wind from a coronal hole.

An impressively tall and long-lasting filament is lurking above the north-west quadrant, just a few days from facing towards Earth.

When the sun is quiet, it's time to tinker!
The Live Solar Events page has been updated with some new real-time solar wind dashboard indicators. These include trend arrows which indicate the trend over the last 15 minutes of data.

This coronal hole could give us uneven bursts of fast wind thanks to active Region 4292 which has emerged right in the middle of it. Expect several magnetic polarity inversions in the fast wind stream too, thanks to this subtle complexity!

An equatorial coronal hole is facing Earth. We should expect some high-latitude aurora activity from this on or around 27 Nov.
Some interesting looking prominences are visible on images from the ground-based Solar Flare Telescope at Mitika, Japan.

A look back at the very active AR4274 which was keeping us entertained for the last two weeks. This is the X1.7 flare on 09 Nov. A huge plasma transfer is seen across a vast distance.

During the last 24 hours the X-ray flux has dropped below the C-floor and it looks like we're in for a quiet period. Of the four sunspot regions on the Earth-facing disc, none are harbouring the ability to produce big flares.

Last night Earth was hit by a minor geomagnetic storm which was actually the edge of the X4 flare on 14 Nov from AR4247. Had the CME been square on to Earth, we might have been facing another G4-G5 storm, and with Earth's magnetic field still weakened by the previous storm, the effect

The active region that's brought us four X-flares in 6 days is sending some parting M-flares as it approaches the west limb. We've had two M1.3 flares since 20h UT this evening.

Solar Flare Alert: A strong X4.0 flare from AR4274 peaked at 08h30 UT 14 Nov. An R3 radio blackout affected south-eastern Africa, Madagascar and Indian Ocean regions.
AR4274 is near the west limb so any CME would not be earth-directed.
Stay tuned for updates.

The CME from the X5.1 flare on the 11th arrived last night just after 20h UT. It had a strong northward Bz (magnetic) component. This initially cancelled out the Earth's magnetic field, so the CME impact and following couple of hours were pretty dull until the Bz finally swung south j

Just a quick note to say that the solar storms over the last couple of days have brought me a lot of new followers on Mastodon, so just a note to them to say "welcome to the feed", and I hope you enjoy it!

There are various predictions for its arrival time, but most are suggesting between 18h and 21h UT today (12 Nov).
