I'm still kind of worried it will do a big CME at earth, but i doubt it.

I hope it does! I'm just worried if it does, that the CME will arrive in the daytime, on a cloudy wet day! I don't think you need to be worried.

Only thing i'm worried about is the grid, but i'd say that it hasn't been doing anything since Monday.

We've already reached G5 more than once from a multi-CME event from this region. We'll be fine.

Which of these is BT/BZ?

In the plot on the left B_N would be the closest, but it doesn't correspond exactly to Bz. "N" is for "normal" ("T" is for "tangential", tangential to the orbit, same as By, and "R" for "radial", same as Bx), but that's normal to the Solar axis of rotation rather than Earth's geomagnetic axis; it's still the closest of the three, though.

Oh, and |B| is Bt; those two bars are standard notation for the magnitude of a vector (the "t" in Bt stands for "total", as in the total strength of the field).

I wanted to ask, if someone (maybe @Misaka ?) has seen recent CME's that could be from this region. I dont know if activity (observable) diminished after its big farside flare.

I haven't noticed anything since the big flare from AR3664 sadly.

Haven't seen any either, mostly filaments from the farside I believe

Same. I just saw something flare from the incoming south and thought it’s this region maybe although it would be too early?

Yesterday region produced the X1 flare

What?

There was no X flare yesterday.

There was no X flare yesterday.

@Philalethes sadly the Stix website does not work on mobiles. Since you’re familiar with it, does Adrian maybe mean something from there?

Nice gif  may I ask the timestamp so I can go take a look in other wavelengths too?

Absolutely!

~13:25 UTC 05/25 is when the flare first poked around the horizon

Yes, it shows an estimated X1 at the time you saw the flare behind the limb, around 12-1PM UTC

Yeah, that's what they meant; there was an estimated X1 there with a range of [M6, X2].

Thanks to you both! The given range of M6-X2 is pretty wide. Do you think.X1 is plausible? I think we didn’t pick up an enhancement here, but unsure. Was there a CME linked to it?

Thankies! Something to look for when I come home

Possible. The one on the top right is from a filament and the one in the middle on the left could have been from the X1 Flare.

Seems fairly narrow if you ask me. X1 seems plausible, but it wouldn't exactly make that much of a difference anywhere within that range (other than the psychological factor of M9.99 being a major letdown and X1 being grounds for cheerful celebration).

I've seem them post those up as X.99 in the past

Honorary X-flares, heh.

Hello, just adding the memory from this storm into the thread. Taken outside of Green Lake, WI.

 

EDIT: I have more if you guys like!

AR 13664 Summary

Infamous AR 13664 (S18) first rotated into view on 1 May 2024.

It then grew to become the largest and most complex AR as of 10 October 2024, with 12 X-class flares.

Then, on 5 May 2024, deltas started forming in the whole area of AR 13664, especially the region initially numbered as AR 13668 (this is where most of the large flares occur).

Then, on 8 May 2024, it produced an X1.04 flare.

Later, on that very same day, it produced an X1.02 flare.

Then, on 9 May 2024, it produced an X2.25 flare.

Later, on that very same day, it produced an X1.12 flare.

Then, on 10 May 2024, it produced an X3.98 flare.

Then, on 11 May 2024, it produced an X5.89 flare.

Later, on that very same day, it produced an X1.54 flare.

Then, on 12 May 2024, it produced an X1.02 flare.

Then, on 14 May 2024, it produced an X1.72 flare.

Later, on that very same day, it produced an X1.25 flare.

Later, on that very same day, it produced an X8.79 flare, the largest earthside flare of SC25 from 14 May 2024 to 3 October 2024, when AR 13842 beat the record with an impulsive X9.05 flare.

It finally rotated out of view on 15 May 2024.

Then, on 15 May 2024, it produced an X3.48 flare, measured X9 on the farside.

It produced several farside flares until it produced its final major X-flare, an X12 on the farside on 20 May 2024.

She was a beaut and will no doubt be talked about for many years to come

Between 8 and 15 May. I wasn't member of this forum then.
