There are three active regions with sunspots with plage that I can see today. One north east, one due west and one south east. A large arched prominence is on the north east limb. A huge broad filament is in the midddle of the northern hemisphere. Three filaments form a square near the south east limb and another arched filament is near the south west limb.

I see we had a CME that caused a geomagnetic storm.

"[i][font="times new roman"]GEOMAGNETIC STORM: A strong geomagnetic storm (Kp=7) is in progress following the impact of a CME during the middle hours of the day on Sept. 9th. This could be the first of several hits from a series of CMEs expected to reach Earth during the weekend. High-latitude sky watchers should be alert for auroras after nightfal[/font][/i]l"

Shame the skies were cloudy [:o]

Hi Paul,

I did look again this morning, but before I could get a sketch the clouds were in. I did notice on the north east limb where yesterdays prominence was more material down towards the eastern marker. This was about three times further out from the limb, perhaps this was the beginning of the CME.

There are eleven active regions today, but I could only manage ten before it went cloudy. AR 11289 contains the largest sunspot with penumbra with two others nearby. AR 11298 is also a large sunspot with penumbra and two more spots.

The remaining active regions as you can see are spread around the disc with numerous smaller spots.

At 9am this morning it was possible to see filaproms in AR 11291, 11293 and 11297.

Two huge looping prominences are along the south east limb and one like a tree along the north west limb.

Great day for viewing solar activity.

Three active regions are visible today two with sunspots. AR 11302 has two unusually long elongated sunspots and one round one. AR 11301 has just one spot. All three regions have accompanying plage and filaments. Prominences are located on the south east and north west limbs.

Six active regions today running in a line from the south east to the north west. AR11302 has the largest sunspots, five in all, AR11303 two and AR 11305 one large one all with plage. I could not see any sunspots in AR11301,11304 and 11307. The long region is littered with filaments some broad. A number of prominences are visible along the north west limb and two along the south east limb. Two prominent ones are almost due west.
A great day for viewing, don't forget the sun cream!

A sketch of the Sun at the Peak Star Party 221011. Three sunspot regions in the southern hemisphere with five sunspots. Several large prominences on the north west, south east and west limbs.

Huge prominence on the south west limb arching into space, could turn into an enormous mass ejection. Another large one is also on the eastern limb. Smaller ones are along the north west and south east limbs. A huge long ribbon like filament is within the eastern quarter of the disc, Other filaments are visible in each quarter. There are nine sunspot regions, I only managed four because of poor seeing. Each region has plage. A very active Sun today!

Just had another go in the gale outside! Managed to pick up three more active regions, but two of them don't appear to be on the solar observatories images?

A very active Sun again today with nine active regions, I was able to label eight of them, missed one, but found another, all accompanied by plage!
The busiest region is the north west quarter with four AR's and six sunspots, one very large. Two very long filaments as on Sunday are in the disc. Three sunspots are in the north east quarter and four in the south east quarter. Numerous prominences are around the disc two large ones one due east and one almost due north. Happy hunting.
I think I overdid it with the artistic licence with squiggles in the disc.
