Keep in mind that the region is close to the limb so it’s exact magnetic layout can’t be seen yet. That’s a part of the explanation. Otherwise a regions magnetic field lines can just sometimes interfere and produce a flare despite the magnetic layout, those are like Marcel already said some surprises of the Sun. Don’t break your head on it 4 Link to comment Share on other sites More sharing options...

The limb curse will probably strike again. I wouldn't be surprised if it's all nice and quiet while earth directed and then when it's closing the limb again it will go off haha 1 1 Link to comment Share on other sites More sharing options...

Well, you see, when a daddy flare and a mommy flare love each other very much... Jokes aside though, I have no idea either. Still waiting for it to come clearer into view, but this seems to me like one of those "out of nowhere" cases; perhaps very strong subsurface activity? Maybe most flares and eruptions from highly active regions are more like active volcanoes that are expected to possibly erupt, while events like this is more like a dormant volcano suddenly erupting out of nowhere due to activity far below the surface. No idea if this is an accurate analogy at all, neither in general nor in this particular case, but I have to at least try to explain things in terms of what I can understand better. 3 Link to comment Share on other sites More sharing options...

I wouldn't be surprised if it's all nice and quiet while earth directed and then when it's closing the limb again it will go off haha Yeah we could see new flux developing as it leaves center disk and activity ramping up again as it approaches the East limb, wouldn't be the first time that has happened this cycle. It could even erupt with a full halo CME that never arrives. I'm not sure how that happens, but it does. I do however think that the curse(s) may be in part a byproduct of our human brains and their inherent biases as well as some fundamental gaps in knowledge. 1 Link to comment Share on other sites More sharing options...

A bit confused with all the EIt wave, shock wave and "earth directed component" talk 32 minutes ago, arjemma said: Really nice eruption with nice coronal waves and STEREO A shows full halo CME although the most of the ejecta going upwards. Will be interesting to see LASCO images but it does look like it might have an earth directed component even if the most of it seems to miss us. I'm so impatient for LASCO now... 🙄 Keep me updated! 1 Link to comment Share on other sites More sharing options...

Right now it's more of a guess that it might have a earth directed component depending on how the dimming and STEREO A coronagraph's looks. Nothing is for certain though and we must wait for LASCO. It does look that STEREO A at least will be hit, but we don't know for earth yet. 1 Link to comment Share on other sites More sharing options...

hamateur 1953 Posted February 17, 2023 Share Posted February 17, 2023 (edited) Of course, naturally. What I find amazing is the sloooow descent. Just checked: The sfu max for that was 550. We get a days total at 22: 00 utc from Penticton BC Canada. Edited February 18, 2023 by hamateur 1953 Min corrected me on utc/ final Link to comment Share on other sites More sharing options...

Cronus Posted February 17, 2023 Share Posted February 17, 2023 The integral of that flare is pretty interesting. Say I was interested in the total mass of a flare. Is there a tool for that? Link to comment Share on other sites More sharing options...

I didn't search very hard, but I struggled with finding any sites providing relatively "live" data (e.g. updated hourly or so). I see the front page on this site also reflects the higher flux, so I assume that's being taken from such a "live" source as well.

Theres no live data to sfi, sadly. they take 3 measurements per day. 18/20/22 UTC and they always use the 20UTC measurement as the official daily flux. but this number is obscured due to the flaring, and is thus not to be taken serious. 2 Link to comment Share on other sites More sharing options...

hamateur 1953 Posted February 17, 2023 Share Posted February 17, 2023 (edited) Using our site for live flux and the published three times daily source available as a link “ flux data” on solar ham. Look at the far left column obs for observed or OBS after scrolling to today’s date. They just called out 182 for today and Thank you Min! as always she catches my errors….. 🤣🤣👍 Edited February 17, 2023 by hamateur 1953 2 Link to comment Share on other sites More sharing options...

But yeah, I guess it was just "lucky" that the flare happened right in the middle of the daily flux measurements with regards to how it's reflected on the front page.

MinYoongi Posted February 17, 2023 Author Share Posted February 17, 2023 By the way, has the Region changed since the flare? I didnt happen to look at SDO thoroughly earlier and the Movies are always a bit small. Link to comment Share on other sites More sharing options...
IlikeAuroras Posted February 17, 2023 Share Posted February 17, 2023 I feel like strong sunspot regions launch X-flares when they enter our view and weaken when they're directly at Earth Link to comment Share on other sites More sharing options...
Jesterface23 Posted February 17, 2023 Share Posted February 17, 2023 I'd put a preliminary arrival time for STEREO A at around /20 01:30Z -9/+6 hours at a travel time of ~53.4 hours. Earth might be a few hours later, but waiting on SOHO's imagery like everyone else. Link to comment Share on other sites More sharing options...
