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….

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!

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.

Someone definitely wanted to say hello to us. Sadly no rise in the protons as far as I can see.

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.

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

Wasn't solely referring to CMEs, but after the M6.8 flare they rose pretty rapidly.

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 🙂

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.

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.

 

this one looks different to me, very aggressive

That was exactly my impression!  In 131 ang. it looks really irritated!

Look at the long range magnetic line reach 3571 has!
