IS THE N. POLAR CROWN FILAMENT ABOUT ERUPT AGAIN? This 2-day movie shows a string of filament segments stretching round the N solar polar coronal hole & they seem to be slowly rising - usually the first hint that a filament may erupt. If it all goes at once it will be spectacular

Southern hemisphere dominant. 5) 9 CMEs.

WHAT A DIFFERENCE A DAY MAKES! Yesterday, a small active region, apparently no different from dozens of others, came over the northeast limb. But since then, it has become extremely active, producing two M flares in the last few hours. I expect more flares from this region soon.

It is odd in the way that it is elongated mainly North-South, not seen many spots like this. Because of differential rotation, it is unlikely that this configuration will last for very long.

VERY HIGH-LATITUDE SUNSPOTS! Can you spot where the new region emerges? The region has 3 significant spots & continues to grow. It is interesting in that it is at latitude of about 38 deg N, twice the current average latitude of N. regions. Note the filament eruption at the end.

THE SUN TODAY:

1) SSN number up to 180, area at 1120 mil.

2) two M flares and several high C level events mostly from AR3282.

3) Something significant behind the NE limb.

4) Unusually high latitude region in the north (see earlier tweet), many spot groups compared to last month.

THE SUN TODAY:

1) SSN up again to 195 and area slightly higher at 1170.

2) Only a C5 flare yesterday.

3) More to come over the NE limb?

4) Note the prominence at the N pole looks as if about to erupt. No new regions emerged. AR3272 decaying rapidly.

5) A lot of C flares yesterday

The problem with sunspot numbers. The sunspot number is defined as the number of groups x 10 +the number of spots. Look at the sunspots from today (top frame). How many different sunspot groups are there?
Now look at the magnetogram below. Does that change your numbers? It should

BTW, a thief, troll and doxxer by the name of Booby thinks this thread should be in his destroyed Environment board.

Not wanting to post in that toilet of a board with its incompetent clown of a Mod but this thread is not about “environment” but just describing the cycle of our sun. Only impacts on us are bright aurora and some communications breakdonws in certain frequency bands. Not an urgent environmental problem Grin

Further more, the sun does not drive climate—solar variations are just too damn small. The sun does not drive seasons or ocean currents—that is the shape of the globe, its continents etc. Even major ice ages are not caused by the sun but by perturbations of our orbit, inclination etc.

So this thread is fine here. It is just science.

CME WATCH - 2023.04.15: Sorry, forgot to upload this last night. We start with the continuation of the multiple CMEs off the E limb. Note how the streamer above the S pole intensifying before erupting and is still there to do it again. Then a couple of modest CMEs off the SW limb

CME WATCH - 2023.-04.16: There is a very fast and bright coronal mass ejection off the southeast limb near the end of the video. Note also the streamer above the south pole is getting brighter and may erupt soon.

A VERY LARGE BUT FAINT FILAMENT ERUPTION:
Watch the dark filament coming in from the left and curling back on itself to the south. It gradually rises and spreads west like a wave covering nearly half the Sun, leaving behind it the classic two bright ribbons on the Sun's surface.

We missed out on a couple days data:

Quote:

Keith Strong@drkstrong·9h

THE SUN TODAY: Helioviewer working again - at last!

1) SSN down to 140, area 890 mil.

2) Only a C7 flare in the last day.

3) More activity promised over NE limb but so far no sunspots.

4) Two new numbered regions AR3283/3284. two new tiny spot regions emerged out ahead of AR3282.

MAGNETIC BALLET: Two sunspot groups on the W. limb of the Sun are in opposing hemispheres and seem to be battling out which has the strongest field. The southern one seems to be more active but the flow is mostly from north to south. Note how shoch wave one jet disrupts the flow

CME WATCH - 2023.04.18: The bright streamer near the S. pole of the Sun produced a second modest coronal mass ejection but not the major one I was expecting. Some activity (slow outflow or minor CME?) above the SE limb. Almost no activity in the northern hemisphere for 2 days.
