Looking briefly at the archive it doesn't seem that way, but I could have missed something. I agree. It is currently sitting at around Carrington longitude 73 and 9deg south. The nearest match I can find is AR3389 which was a small Alpha spot at C67 / -9 for the first part of the last rotation. It was then recorded as a Plage for 5 days, but re-appeared for 1 day and was recorded at C54 /-16. My guess would be that there has been some development in the fields in that area, so it would probably be reasonable to call it a new spot.

hamateur 1953 Posted August 23, 2023 Share Posted August 23, 2023 Hey guys Newbie just gave me a heads up on a huge pair that looks like Southern Hemisphere but close to equator and arriving soon. Hopefully she will post something definitive here soon. My untrained eyeballs say its 1500 or better. Keep fingers crossed. Later, Mike/Hagrid 1 1 Link to comment Share on other sites More sharing options...

And by 1500 I assume you mean area in µh (microhemispheres)? Sounds interesting, color me intrigued. Looking at the latest Mastcam images I see a series of images like this one were taken on August 20 (3 days ago), and I can make out the spots I believe you're referring to: Given the current heliocentric separation angle between Earth and Mars of ~135°, I'd estimate that we'll see these spots rotating into view in 2-3 days, maybe even less. Actually, now that I think about it I'm not exactly sure about how this image is oriented, I'm thinking it might not be reoriented the way most of the imagery specific to Solar observations is. That complicates the matter a bit. Also not sure exactly what the darker areas really represent, but I'm assuming only umbrae would be clearly visible in imagery like that. Maybe not, but if so it does look like some very large spots indeed. 2 1 Link to comment Share on other sites More sharing options...

There are quite a few news articles running now including the one above 👆 which I have only just discovered lol. Timeframe possibly the weekend or before. N.

Looks like it would be the general area, but not sure exactly where in that region it is, could be closer to the 60-degree line too, but somewhere between 40-60 sounds right to me.

cgrant26 Posted August 23, 2023 Share Posted August 23, 2023 (edited) I'm looking forward to a better view of 3415. Too early to tell but might be a nice delta in there. Just can't quite tell yet if that's a shared umbra. Edited August 23, 2023 by cgrant26 2 Link to comment Share on other sites More sharing options...

hamateur 1953 Posted August 26, 2023 Share Posted August 26, 2023 That seems to be a pretty big trans equatorial loop in 131 angstroms currently. Sure hope it’s an announcement and not another disappointment! 🙂 3 Link to comment Share on other sites More sharing options...

Sure hope it’s an announcement and not another disappointment! 🙂 yep, looks quite solid according to gong it just formed, and according to jsoc (i trust it more, personally) it is quite old it will take us 2-3 days to see it, hoping for the best looking at jsoc gif about development of active regions, this region has grown in past +-4 days in the place where in the past were 3394 and 3363, so yes, we have a lot to hope for Edited August 26, 2023 by tniickck 1 1 Link to comment Share on other sites More sharing options...

cheebee Posted August 27, 2023 Share Posted August 27, 2023 that eruption from the eastern limb on AIA 094 was absolutely stunning! i look forward to seeing the rest of it. its getting fruity out there 1 Link to comment Share on other sites More sharing options...
hamateur 1953 Posted August 27, 2023 Share Posted August 27, 2023 Indeed it was! I’ve been rewatching sdo 131 angstroms 48 hr run repeatedly because it is one of the cooler explosions I have witnessed! Solar Ham estimated 48-72 hrs until this region shows its face.

It certainly looks interesting around longitude 330 to 345, but I'm not so sure about the near equatorial region. Of course, there could have been some development of the negative field in that area.
