Jan Alvestad at Solen https://solen.info/solar/index.html seems to agree. He often challenges the SWPC attributions, so I suspect that it is correct on this occasion. Even, so this AR has made a good entrance ! Edited July 12, 2023 by 3gMike added link to Solen 1 Link to comment Share on other sites More sharing options...

If you're talking about the one from yesterday (M6.7 on GOES-18, M6.8 on GOES-16), that was definitely this region and not 3368: 2 Link to comment Share on other sites More sharing options...

Having seen the image posted by Philalethes above, I would be inclined to agree with you but we need to understand why experts are claiming something different. It is also worth noting that on several occasions yesterday simultaneous flaring was noted on opposite sides of the disk with ARs 3361, 3363, 3366 and 3368 all flaring at the same time as 3372 at one time or another. 1 Link to comment Share on other sites More sharing options...

Even more obvious when watching the video from SDO too, which the image is a still from; not sure why they'd both assign it to the wrong region, but maybe Jan just didn't double-check it. I agree that there has been a lot of simultaneous flaring from both regions, but that's mostly been lower-level flaring, and there wasn't really much activity near 3368 during that major flare. I don't think there's much chance of this really being from there, so I'm assuming SWPC and Jan are simply wrong here whatever the reason might be. 2 Link to comment Share on other sites More sharing options...

hamateur 1953 Posted July 12, 2023 Share Posted July 12, 2023 (edited) lots of mistakes yesterday and easy to understand why!  If anyone but us hams cares sfi is looking better every day!  Our F layer is getting a nice bath of UV currently. @KW2P produced an excellent blurb ( his words) in our amateur radio subsection for those who are interested in radio propagation. Edited July 12, 2023 by hamateur 1953 afterthoughts 1 Link to comment Share on other sites More sharing options...

mozy Posted July 13, 2023 Share Posted July 13, 2023 The main delta that flared constantly decayed after the latest M 6.9 flare, you could see spots fading out on SDO's loop shortly after it, probably why the activity halted. 2 Link to comment Share on other sites More sharing options...

Tormentius Posted July 16, 2023 Share Posted July 16, 2023 Hey guys, a little confused about the latest update from this region. In their latest forecast update, NOAA claims this region as beta-gamma-delta and Solar Ham says the same on his site. But on NOAA’s Solar Region Summary which is updated at the same time it is still listed as Beta-Delta as it is on the site here. So, I’m a little confused. Did NOAA make an error here? 1 Link to comment Share on other sites More sharing options...
Jesterface23 Posted July 16, 2023 Share Posted July 16, 2023 It's up to Beta-Gamma-Delta now. There's probably a quick data feed available somewhere, and there is the timing of when the data is obtained. 2 Link to comment Share on other sites More sharing options...
Philalethes Posted July 18, 2023 Share Posted July 18, 2023 Hard to believe that a measly C5 could be responsible for the purported 1200 km/s eruption suggested by the radio emission, but in 304 Ã… there does seem to be some sort of eruption at that point. Doesn't quite look like a filament eruption though, looks closer to the dark plasma eruption we saw recently in the southern hemisphere. Anyone got any ideas about this?

Jesterface23 Posted July 19, 2023 Share Posted July 19, 2023 The CME came from 3376. A weak western far side CME is just adding a little bit more difficulty. 1 Link to comment Share on other sites More sharing options...
