Solar activity

New sunspot region emerged yesterday at late evening and today has already received number (AR 3483). Looks like region develops rapidly and shows nice activity.

The 3489 region that will be facing us soon has been obviously developing its magnetic complexity and is currently rated Beta-Delta. It may produce flares soon if it continues to develop its magnetic complexity.

doesnt in look like it has kind of reversed polarities? there is also a tiny delta

I don’t know if theres some confusion, unlikely perhaps. However currently solar soft shows this AR as the most active. The next week should certainly be a lot more interesting.

Hi! I'm new to all of this, but hoping to gain a little more understanding. CME0016 is listed as a IV for potential full halo. Lifted off 11/15 starting at 7:48. Cactus puts the median velocity at 600 km/s but I can't seem to find any associated event or flare with this? The angles make me think this might be one of the detections off the northeast limb that everyone is talking about for incoming regions? But I'm also not entirely sure if I'm reading that correctly. Is anyone able to shed a little light into how to accurately differentiate origin points with this particular data set? I can provide the link to cactus, this forum doesn't support posting screen shots and I c…

The spaceweatherlive archive records the last day without sunspots was 2022-Jun-08. The current sunspot number is 23, from 2 active regions with 3 sunspots. What is the likelihood that we might have another sunspotless day in the next few days - which would be unusual so close to solar maximum. It may depend on what's coming around the east limb - whether the bright regions contain sunspots or just flux.

Looking at today's solar weather, I noticed a bunch of strange white spots in 193å image, which are also visible in SOHO EIT 171 and 284. This is something I have not seen before, but since it's only been about 3 years that I look at the solar weather more closely, I hardly have seen anything. However, I haven't found anything on those spots, and I wonder what that could be? Considering that we are moving towards a solar cycle peak, it could actually be small flares, but so many and spread all over the visible side of Sol? What else could it be? Best visible in SDO AIA 193å from 2023-11-14 21:47:05 UT.

This AR was responsible for C7.1 just now. Weak delta and some polarity intermixing. N.

An M1.7 flare from this region just a while ago. looked pretty impulsive and i cant see ejecta on SUVI.. or lasco. there is a cme in lasco starting at 7:30UTC though but no flare is visible.

Arrived and already accredited with two M class flares to date. Certainly an improvement! Bears watching imho.

One to lookout for today as It's been growing nicely, already gained 2 deltas with increased mixing.

Can anyone explain this to me? How is it possible?

I numerically calculated the following numbers with an error of 1 degree. The geocentric longitude of the Sun on 25 November 1999 at 00:00 UT was 243.52 degrees. On this date, from sunspot number 8771, an M2.0 class of flare started occurring at 18:59 hours and ended at 19:29 hours. This sunspot was located at S15W40. On this date, the ecliptic longitude of Jupiter was 32.92 degrees and its geocentric longitude was 26.20 degrees. I would like to know whether the solar flares from the flaring region be visible from Jupiter. Help me to understand the geometry of the alignment of the location of the sunspot 8771 w.r.t. the Jupiter.

This southern AR announced itself by kicking out that M1.79 and a non earth-directed CME practically immediately when it arrived. It appears to be growing rapidly and bears watching. One C.6 and two lower ones. I see what might be a tiny delta in the leading neg spot, however will defer to others better at the delta spotting than myself for now.

This AR announced itself immediately on arrival. SWPC should give it a designation later today. Near M class and another weird “ mountain” flux signature It seems. Location: per solar soft It doesn’t resemble a filament to me anyway. Should prove interesting. looks like it wanted to join the party. ok then. Jan Alvestad ( star) notes 16 spots already on this rapidly developing AR. S 21 East 16 probably now Edit: wed it is still growing Jan (STAR) apparently sees a weak delta somewhere. I can’t find it however and it still isn’t doing much yet….

it looks pretty strange and has a few deltas in it, deserves a topic

Solar soft lists this AR as being responsible for two M class and a near M just a bit ago. ( error. Was actually 3437 evidently) Nevertheless Probably deserving of its own topic.

M4, not bad! Flux signature looks impulsive though.

these two look particularly spicy to me, already kicking off with M class. sorry i just saw the other post 😕

Will update the topic title once the spot gets its designation, but it's referring to the newly appeared one near center, at around 7-10N and 13-15W; looks like the polarities aren't where they should be, slightly reversed. Always keeping an eye on these regions whenever I see them. Still pretty small though, and no real complexity.

Looks like there was some eruptive activity associated with the flare just now.

Well, I didn’t see that this guy had a thread yet. It has dealt out three C class and is looking like it may still be building into an M class guy. It seems to have consolidated in the last two days at least.

this region developed spots within last 18 hours and started erupting with C-flares, we should watch it

a small delta now, and it keeps producing small flares

i think we need a topic for this one. might be a delta, actually, though it is less than 1 day old and too close to the limb
