Only time will tell. 1 hour ago, Orneno said: Yeah, it’s calmed down the CMEs unfortunately Yeah, it is bright! But Orneno and You are right. Im just confused that it's growing very rapidly (1000+ strength in like a day) but calming down and also not being on the GONG + Stereo Maps anymore. Maybe thats due to its close limb proximity? I'll edit this and attach some pictures in a short while. Link to comment Share on other sites More sharing options...
Solarflaretracker200 Posted May 2, 2022 Author Share Posted May 2, 2022 It must not be complex at all. But then again this could be faculae Link to comment Share on other sites More sharing options...

I'll never trust these farside images 😅 On another note, we got 2 fast growing regions near center disk, might wanna start a new thread for them soon.

May i ask why? Yep! Saw that. But i think for them its almost like a week until we see them on the limb/stereo so i'll wait 1-2 more days to see if they persist.

They usually always look way bigger & better than what they actually are, just giving false hopes to people I assume It'll be the same for this region as it's super quiet.

Which is the cycle we are in, as you may know Oh that's cool! Does the number of the solar cycle mean how many we have gone through or how many years it could last? On 5/1/2022 at 11:11 AM, Orneno said: Also, welcome to the website! Thank you! People seem kind here already! Another question... Is it a guess or do we have something on the back side of the sun that tells you this is Ar 2992? Link to comment Share on other sites More sharing options...

Since humans started counting them, that is. The sun's probably been doing it since before the Earth formed. 30 minutes ago, SunspotRager93 said: Another question... Is it a guess or do we have something on the back side of the sun that tells you this is Ar 2992? We know exactly when it rotated around the west limb, and we know exactly how long it will take to re-appear at the east limb, if it survived, and we know exactly how far north/south it was. Because we can see something bright is flaring just behind the east limb (and also can see it on the rudimentary helio-seismology images), and we know that's about where 2992 should be, and there were no other regions close to 2992, it's a pretty safe guess that this region is 2992 returning. Because 2992 fired off some powerful flares right as it was going over the west limb, it's a pretty safe bet that it is the source of the farside CMEs and flares we have just been able to glimpse over the limb. It's technically possible 2992 could have decayed away to nothing, and a new but also complex and active spot appeared in almost the exact same spot during the area's trip around the backside of the sun, but this is highly unlikely. That would be fast for spots to decay and grow, especially a complex and active one like 2992 was and this incoming region appears to be. But no, we do not have any direct observation of the farside of the sun. STEREO A is a little bit ahead of Earth in Earth's orbit, with it we can see a little ways behind the east limb of the Earth-facing disk. The region in question, 2992 returning, is actually visible on STEREO A already. Unfortunately, it only has two wavelengths of imagery, and we can't actually see the sunspot or gauge its complexity, nor measure flares. So, not very helpful. You may see some "farside imagery", that uses "helio-seismology", the practice of measuring the vibrations in the sun that are caused by large active sunspot groups. This gives us a hint at farside imagery, at least the large active sunspots, but it is rudimentary and not very reliable.

Does anyone know that? It looks impressive in Suvi/SDO @mozy ! But i dont know if its really a sign of regrowth or anything. What do you guys think?

Does anyone know that? It looks impressive in Suvi/SDO @mozy Impressive is probably the last word I would use for that flare, more like passing gas. Nevertheless, always a good sign to see something rather than it being constantly quiet. Edited May 2, 2022 by mozy 1 Link to comment Share on other sites More sharing options...

For some reason I thought there was more than as many questions that have been asked 🤣 I guess we can just kill time by answering questions bc there is nothing much else to do lol Well now that has been said...

Well Stereo B took pictures of the farside and Stereo A which is still around, takes pictures of the earth facing side of the sun. So put the two together... and you had a full field of view of the sun. Link to comment Share on other sites More sharing options...

Or does it make those regions appear better than they are like EUVI? is this the first little sunspot? Does it look like a delta ? (in front of the maybe bigger spots?) or is it just plage? to me it looks like 2 little sunspots with a "big" sunspot (very close to the limb)..
