hamateur 1953 Posted February 2 Share Posted February 2 This southern region appears to be the source of the M 1.18 just a bit ago and the leading spot resembles a sparkler in 131 angstroms right now. I believe I see a delta perhaps also…. 2 Link to comment Share on other sites More sharing options...
Solution Jay-B Posted February 2 Solution Share Posted February 2 It does look like a good candidate for and earth directed cme if it can keep up the complexity as it turns to face us! 4 Link to comment Share on other sites More sharing options...
Drax Spacex Posted February 2 Share Posted February 2 (edited) Somehow this flare released a dark puff of ejecta almost due west, visible in SUVI 195. It may have been reabsorbed near the edge of the southern coronal hole. Hurray for the underdog alpha sunspot to erupt with an M flare and a Type II radio emission.

Adohran Posted February 2 Share Posted February 2 Someone definitely wanted to say hello to us. Sadly no rise in the protons as far as I can see. Link to comment Share on other sites More sharing options...

Hurray for the underdog alpha sunspot to erupt with an M flare and a Type II radio emission. 3571 Seems to be the culprit region that had numerous prominence eruptions and the Type II radio emissions beyond the eastern limb. It was during the M 6.8 flare as well. 40 minutes ago, Adohran said: Someone definitely wanted to say hello to us. Sadly no rise in the protons as far as I can see. Protons don't necessarily need to rise moments after a flare if you're referring to a CME launch. Although they did start to slowly ascend a few hours ago. Type II radio emissions are also a good indicator for a possible solar storm associated with a flare. Edit: I wanted to clarify that I am referring to low energy protons Edited February 2 by Parabolic Link to comment Share on other sites More sharing options...
Adohran Posted February 2 Share Posted February 2 Wasn't solely referring to CMEs, but after the M6.8 flare they rose pretty rapidly. 1 Link to comment Share on other sites More sharing options...

My I ask why you're interested in proton flux? I'm only curious because I enjoy learning new aspects or mechanics of SEP's 🙂 Link to comment Share on other sites More sharing options...
Philalethes Posted February 2 Share Posted February 2 11 hours ago, Adohran said: Wasn't solely referring to CMEs, but after the M6.8 flare they rose pretty rapidly. Only the protons with the highest energy, i.e. which move the fastest, will be seen to rise rapidly after an event, and such high-energy protons are generally only emitted by the most explosive events; in the event you mention we even saw a rapid rise in ≥100 MeV protons, which is quite rare from my experience. This one doesn't really seem nearly as energetic in comparison, and in those cases you'll generally either only see protons of lower energy rise more slowly if there's a CME approaching, or not really see any noticeable increase at all. Another point to consider is that the Parker spiral is twisted counterclockwise, and charged particles will tend to move along field lines as they move outward, so typically rapid proton rises will happen more from events from the other side of the visible disc. 2 Link to comment Share on other sites More sharing options...
Drax Spacex Posted February 3 Share Posted February 3 Alpha AR3571 continues be indefatigably fussy. Lots of C flares and small sputtering storms. It just might break out in an Earth-directed CME conniption soon. 2 Link to comment Share on other sites More sharing options...

In 131 ang. it looks really irritated! 🤣🤣🤣💥 Edited February 3 by hamateur 1953 1 Link to comment Share on other sites More sharing options...
Jay-B Posted February 6 Share Posted February 6 Look at the long range magnetic line reach 3571 has! Link to comment Share on other sites More sharing options...
