Drax Spacex Posted July 20, 2021 Share Posted July 20, 2021 (edited) "What looks to be a massive sunspot region" has begun rotating into the earth-facing solar disk. Someone was proactive in defining AR2847 early, as I don't see it in the latest Synoptic Map (20-Jul-21 1328UT). Better I think to start a track early with an AR so that any early flares from it can be attributed to it. Initial magnetic classification=Beta, sunspot classification=CRO. It will be interesting to see how AR2847 evolves and whether additional ARs will be defined for this large area of flux and sunspots. The area spans about 20° in latitude and 30° in longitude (how many Earth's could you fit in that?)

Jesterface23 Posted July 21, 2021 Share Posted July 21, 2021 The best way to look at it seems to be through STREO A's EUVI 304 imagery. 1 Link to comment Share on other sites More sharing options...
Newbie Posted July 21, 2021 Share Posted July 21, 2021 (edited) Just a few little spots to begin with! Lets see how it develops as it rotates further. Solar flux has increased to 87. STEREO Ahead EUVI 195 (latest) is what I follow.... it's a pretty green colour Edited July 21, 2021 by Newbie 1 Link to comment Share on other sites More sharing options...

Btw, its 2847 not 2827 Edited July 21, 2021 by abc Link to comment Share on other sites More sharing options...

Drax Spacex Posted July 21, 2021 Author Share Posted July 21, 2021 AR2847 (thanks for the correction) is not large, but the broader area of bright scintillating solar flux is quite large. I was estimating the size by looking at the image "EUVI/AIA 195 Stonyhurst Heliographic (Earth-view)" under the Far Side section at the bottom of https://www.spaceweatherlive.com/#tab_solar It is yet to be determined how many additional sunspots and AR's this bright solar flux area may contain - we'll know in a few days as it rotates fully into Earth view. 2 Link to comment Share on other sites More sharing options...

If you look at the current image of AR2847 (21/07/21 10:00 UTC) it looks like another large region is entering the eastern limb at a lower latitude.

Newbie Posted July 21, 2021 Share Posted July 21, 2021 Hi Minyoongi, You can get a good photo of the activity behind the east limb by looking at the STEREO EUVI 195 images. You can choose the resolution of the image and there is a whole list of archived images as well. Go to the SWL solar activity tab and choose STEREO from the drop down menu.

Drax Spacex Posted July 21, 2021 Author Share Posted July 21, 2021 (edited) AR2849 was likely a primary contributor to far side activity. We'll see if it has any sizzle left now that it's rounding the bend. Solar flux has increased. Edited July 21, 2021 by Drax Spacex Link to comment Share on other sites More sharing options...
Newbie Posted July 21, 2021 Share Posted July 21, 2021 (edited) Oh that I had the wings of a dove that I could have flown to the other side of the Sun last week! Or at least a better pair of wings than Icarus had 😄 for I fear that all we are left with now is a sunspot graveyard! I would love to be proven wrong!

All things grow from graveyards, and there will be plenty of explosions to see tomorrow (figuratively, I'm not predicting anything for tomorrow.)

Drax Spacex Posted July 22, 2021 Author Share Posted July 22, 2021 Now that the region has rotated into Earth-view, it does look more like a large plage area with only a few simple sunspots. A head fake, a deke, from our crafty Sun. 2 Link to comment Share on other sites More sharing options...

Yeah not safe to stick your head on the block by making predictions, 😁 but as others have said, it seems to be the way of our Sun at the moment, always throwing us a curved ball. If all the fun stuff had occurred on our side of the Sun we'd all be saying what a fantastic start to SC25! 1 Link to comment Share on other sites More sharing options...

A bit surprising (why do I keep saying that?) given the tiny sunspot / pores for this region are barely visible in the HMI intensitygram. 1 sunspot, size 10, alpha, AXX.

Overall there is a 25% chance of a C class flare but for AR2849 it is only 5%. I didn't see it coming. Still, any activity is good.

We'll have to wait until the X-ray flux drops below C-Class and for LASCO for info on it, so it'll probably be a few hours. As for its strength... Probably weak, but I'm a beginner when it comes to this. Edit: And now there seems to be another flare going on right now.

Jesterface23 Posted July 24, 2021 Share Posted July 24, 2021 STEREO A will get the best out of the CME. It looks to be very slightly Earth directed, but so far my thought is I don't think it will make it to Earth. Link to comment Share on other sites More sharing options...
