CME WATCH - 2023.02.19: I am using the LASCO C2 and C3 fields of view today because the scale of the events is so large. I forecasted that the SW stream was going to erupt (see earlier tweet) and it did

UNTWISTING MAGNETIC FEILDS: A huge prominence on the west limb slowly untwists as it erupts. Note its size compared to our Earth. This explains at least one of the two CMEs off the west limb. They were large and may affect the Earth in a couple of days.

THE SUN TODAY: 1) SSN leaps up to 165.
2) A host of small to moderate C flares.
3) STEREO A shows three potential new spot regions behind the E limb
4) The 4 big C flares were from 4 different regions. Lots of tiny spots emerging, will they amount to anything?
5) 6 CMEs yesterday


165 sunspots.  Not a GSM then. Dubyne LIED!

TRANS-EQUATORIAL LOOPS: This arcade of magnetic loops straddle the Sun's equator on the west limb. You could lay 25 Earths along them. This is seen at a temperature of about 2.5 MK - it has to be that hot for the pressure in the loops to be able to support such a large structure.

NEW REGION PRODUCES IMPULSIVE FLARE: The new spot region on the NE limb produced a very impulsive M4 flare about 3 hours ago. The LDE X flare the other day lasted for about 24 hours, this flare lasted barely 15 minutes. Impulsive flares are caused by compact, dense flare kernels.

CME WATCH - 2023.02.20: Two main areas of CME activity. The most spectacular events seem to be in the SW with a series of large CMES. But there is some significant outflow from the NE and right at the end a large event. Compare their size with the white solar disk in the middle.

THE SUN TODAY: 1) SSN down to 120 (note yesterday's value was downgraded).
2) 2 M flares & some moderate to high level C flares.
3) Still some promise of two new regions behind the E limb.
4) Most of the activity seems to be coming from AR3234 on the NE limb.
5) 9 CMEs yesterday.

AN EVEN BIGGER FLARE: The new region on the NE limb (AR3234) just produced another impulsive flare. This time it was an M5 event. Is the region building to another X flare in the coming days? Quite possibly. Only time will tell, stay tuned.

CME WATCH - 2023.02.21: The bright streamer in the NE erupts 4 times, presumably associated with the large M flares we have observed there today. There is a smaller, fainter CME in the NW and a fairly violent one in the SW towards the end.

THE SUN TODAY: 1) SSN drops to about 100 as more regions disappear over the W limb.
2) Two M flares in the last day, with lots of C flares, including some moderate to high events.
3) More regions behind the E limb.
4) Most of the activity coming from AR3234 but AR3230 is growing.

CORONAL HOLE ALERT: We have 2 large coronal holes on the Sun currently. The one near the south pole of the Sun is probably not a threat to give us a geomagnetic storm as it is too far south. The one on the equator is too far east, but will soon move into a more favorable position

GROWING SUNSPOT REGION:  Active region AR3230 in the SE quadrant of the Sun has surprising started to regrow. It started off as a single large spot which is usually the remnants of a mature region, but in the last day it has developed new spots in the trailer part of the region.

NOTICE A PATTERN? We have had 4 M flares in 2 days. The timing between them is spookily similar - just a few minutes under 9 hours. Coincidence? Possibly. Time for more energy to build up? Possibly. Assuming that the rate does not change, the next big flare will be at 23:00 U.T.!

A gorgeous picture of our Sun taken in H-alpha (a red line in the optical spectrum) - shows the relatively cool part of the solar atmosphere.  The bright areas on the limb are prominences, compare with my earlier tweet.

CME WATCH - 2023.02.22: There is a beautiful slow and elegant CME off the south pole, followed by a rapid bright CME off the NE limb. The video is short so there may be some missing data.
