I guess you mean the one with the pink circle?😅👇🏻

Yes absolutely @Malisha Reuvekamp

Spectacular eruption. 

I just saw that, looks very pretty, but I don't know if there's anything to it.

 

Big and fast!

it also triggered that prominence to move a little as well 

Impressive filament eruption, Even the 500 MeV protons are rising.

It could be that one shaped like a 3 that finally let loose

that cme looks realy dense and fast.

is this from the filament on the west

is this the same event?

wow, have we seen this this cycle already?

Neutrons are increasing at the south pole monitors.

S1 minor radiation storm in progress.

what does that mean? i have never paid attention to that. does that reflect the S1?

Qu'est-ce que ça veut dire ? Je n'y ai jamais prêté attention. Est-ce que cela reflète le S1 ?

 

It's a GLE. a GLE is an increase in cosmic ray flux at ground level

why does that happen? Have we seen this this cycle? what does that mean for any potential proton storm?

When a solar flare becomes very strong it is possible that particles even more energetic than 500Mev protons are released and arrive at ground level. this is very rare the last one dates back to November 23, 2023. I just turned on my cosmic ray detector, I hope I will detect this GLE

There is a background level of neutrons that is produced from cosmic rays hitting the atmosphere. High energy solar protons can produce additional neutrons and increase the counts at neutron monitors on the ground.

If protons have high enough energy they can penetrate Earth's magnetic field and create free neutrons when they smash into molecules in the upper atmosphere. Usually when 500MeV protons increase you will start to see an increase in neutrons at the poles. If you have very high energy protons you can get neutron increases at lower latitudes as well. As you get farther from the poles protons need a higher energy to make it through Earth's magnetic field.

Interesting, I noticed that the greater than 100 meV protons had risen along with the lower energy ones and I have heard that those high energy ones rarely go up that far. Do we know if this was a farside flare or filament eruption? @Jesterface23

I think it does relate to S1 but I have heard from Tamitha Skov that the storm level threshold for these >100meV particles is much lower than the other types because the >100meV have a lot more energy and can cause more damage at lower concentrations.

this was a flare from the new rapidly growing sunspot region that crossed the limb,id say x 20 or more

That filament / prominence on the SW limb just keeps stretching waaaaaaaay out.

Okay that makes sense because it is a massive CME and incredibly fast (judging by the chronograph alone)... amazing !! It looks like it rattled that prominence near the sw limb also @hamateur 1953

It looks like STIX is in place to read the flare so hopefully we just have to wait a couple of hours to see how big it really was.

X666

my cosmic ray detector detects activity higher than normal I turned it on 15 minutes ago. I was able to detect 7 muons (cosmic rays) in 3 min instead of 3 or 4 and the flux remains at 5 muons

There was no flare reported. It is a massive filament eruption and lift offs. There has been 3 in the past 4 hours give ore take. South east limb. And the other two off the west limb. Not flares have been reported on any satellite

The last GLE was on May 11, 2024.
