Eruption event east limbo.

On HMII Imagery you can see some spots Trailing behind The leading one.

Looks more like faculae surrounding the region to me then actual sunspots, lets keep an eye out on this one.

Do You think the potential Stuff Trailing behind 4062 is apart of it or separate what do you think.

I'm sure its part of it but not as a sunspot, I use a composite layer of Intensity- and Magnetogram imagery and when I turned the Magnetogram off to see the sunspots there wasn't anything dark trailing behind. Maybe an Area where spots could develop in the future.

Yeah Hopefully 4062 is quiet as of now But Hopefully it grows And Gains Complexity in the Very near future if the Trailing potential plage area can Help with the growth Of 4062 But not looking likely as of now.

I've just found a research paper on the relation between plage and sunspots (https://www.aanda.org/articles/aa/pdf/2020/07/aa37739-20.pdf) and they write:

Chapman et al. (1997) found that facular area conforms to a quadratic relationship with sunspot area. The coefficient of the second-order term is negative, such that the facular-to-sunspot- area ratio decreases as sunspot area increases.

So it seems by observing how the faculae behave around an active region someone can observe how the corrosponding sunspots might evolve around them. Kinda neat to see.

Interesting indeed.

How Shearly Complicated these Sunspots Truly are and how they Evolve and to watch their behavior over time is really cool.

That came Out wrong I mean Cool as in mesmerizing. That was a big oof on my part.

Simultaneous flaring from 4055 (I think) and something behind the eastern limb. Maybe the series of M-flares from the former will come back again soon with the new guy :)

Edit: Went to M1.5 while I was writing this, though it seems 4055 strongly dominated the emissions.

Looks like it is separate from these images . Often hard to tell early on as , as you can see in the images below the limb side streches and blurs .

In my eyes blurry far side is better than no far side picture at all :)

I’m interested in this trailing region since it’s quite large and seems like a consequence of the fresh flux pushing through.

From AIA 1600 it doesn’t look like anything too spectacular but we’re dealing with phenomena that are poorly understood even in 2025 so anything can happen.

To whoever mentioned AIA 1600 as a rough estimate for rate of sunspot growth for predicting AR3664 is an absolute legend

Thank you all once again for educating my chemical engineer brain in sunspot and geomagnetic mechanics.

By the way where do you find the imagery above? Asking for a friend of course ;)

Jhelioviewer . SDO continuum and magnetogram combined with base of 1700 angstrom SDO is the first combination . The second image is just the continuum . Both where rotated 45 degrees by axis using the software .

here is a sticky thread about using the software

Much farther back, over the north-eastern limb, flares are already visible.

Yeah on jsoc you can see another potential big sunspot so will be interesting to keep an eye on it to

seems unstable with almost constant flashing and looks pretty big on farside viewer imagery hopefully by thursday its visible.

The spots in the region, which we observed yesterday with large loops over the eastern limb; we have to wait for it to enter a little more, because it is already showing flares, to further analyze its evolution in magnetic complexity.

Between 00:08:30 UTC and 16:28:54 UTC the SDO generated this activity. The event occurs in the southwestern hemisphere.

There is definitely a hot region on the eastern limb besides new 4062. This was pegged at N 10 latitude east 88 approximately by solar soft. Spitting C flares. I missed these events entirely with the excitement over the incoming CMEs. So next week may finally have some real action…..

Forecast next week for around me isn't the best so i can almost put money on something decent happening.

I made a video with you in mind that's almost finished rendering. Should be another 30 minutes until I can post it but I'll tag you when I do.

For anyone else reading this, cynical humour is an aurora hunters stock in trade or we all would be far crazier than we are now! 🤣🤣

We would need a straight jacket otherwise lol. Others reading this won't realize the ongoing joke we've been having in a few threads too.

Here's a short time-lapse for the east limb. @hamateur 1953 since 131 is one of your favorites I decided to try it with 304

New emerging flows could indicate increased activity

Ladies and gentlemen we have new region appearing on eastern limb of decent complexity.

This one has been extremely bright on AIA 1600 and is responsible for brightness from behind the limb to the north of AR4062.

Peace out ✌️
