*Edit: 

I might have read it wrong, is it even aurora-related you mean, or really just rainbow coloring? 🤣🙈

My tunnel-vision only has aurora in it. 😂

You might find these helpful!

This Aurora Fieldguide & Handbook is made by scientists and citizen scientists, ARCTICS,  with loads of examples and info. Love it! 😍

I don't think is aurora related but i don't know what is it either 😅, hoping someone can illuminate me 😁

Haha, I can see that now. 😂

Probably just a pretty lens flare now taking a better look at it.

What are these ropes over a sunspot? This formed over ~3 hours

I was just commenting on those loops.  I believe them to be Post Eruptive Arches ( arcades) They may follow a CME.  This region should be fully in view by the weekend I hope.  Let’s hope it has more in store for us over the next two weeks!

So far, these questions are many things, but uh... I would not describe any of them as stupid...

Let's say that there is a bright full-halo CME.  Is there anyway to make an educated guess as to what the magnetic field vector orientation (bz) will be within the flux rope when it reaches Earth based on the AiA data, LASCO, GOES, etc?  Or is it all speculation until there is an impact at one of the many solar orbiting satellites or at L1

Picket fence aurora?

Btw quite rare phenomenon 

Was just wondering whether STEVE but doesn’t look like the examples I have seen photographed.  I guess STEVE is seen more often by the Canadians over 50 degrees N from what I have read.

An obvious question would be "Was this only visible on camera, or could it be seen with the naked eye?"

The main image is horribly out of focus, yet that feature seems relatively better focused - does that tell us something?

Also, the curvature, and the fact it seems to cover the whole visible spectrum, suggests it is not aurora related.

The friend who took this said it wasn't visible to the naked eye

If not aurora related, I'd still go with a lens flare, so an effect created by a light source in combination with camera, such as Moon, street lantern what so ever.

They come in many forms and shapes.

Just like when you take a picture during daylight and the sun makes funny shapes, lights, green thingies, tiny rainbow shapes, in your photo. 

Seems smartphone lenses have that problem more often.

Hi all! I'm new here. Like some others here, I started following space weather more closely after seeing and photographing the aurora on May 10 and October 10, though I'm still very much a rookie in terms of knowledge about space weather.

I'm gonna start off with a question. A few weeks ago, the base level flux was around C1.2. At the time, some small C-level flares happened, like C2.0 flares, and were assigned to certain active regions.
At the moment, the base level flux is around C2.3. Am I correct in thinking that if a C2.0 flare happened now, it would not get assigned to a region, as it never passed the base level flux?
Would a M-level flare register and get assigned to an active region if it were to happen while a different region's X-level flare is in progress?

Those are good questions.  A visual or 131 angstrom view from earthside typically will verify a flares origin.  In fact this has come up a few times.  Look for the “X marks the spot” as I have said.  This “ X” is the result of diffraction spikes in the imagery.  Hopefully this helps ya.  Edit:  typically the diffraction spikes are only seen. ( by me at least) with flares in the M region.   We lost solar demon along with stuff from JSOC recently and solar demon was excellent for locating the minor stuff. Welcome aboard btw and Merry Christmas.  Mike.   I guess that was a long way of indicating you were absolutely correct!   Haha.

Thanks for the reply @hamateur 1953, and merry Christmas to you too! Yeah, I've seen the diffraction spikes in the SDO and GOES imagery before. I guess if a decent flare happens during another X-class flare, it's not going to be hard to miss when looking at the imagery, even though it might not get registered like it usually would.

The diffraction spikes remind me of the spikes I see when viewing a bright star with my Newtonian reflector.
I've been meaning to make a white light image of the sun with my telescope since the GONG Intensitygrams seem kind of blurry, but alas, it's been cloudy for weeks now, and I'm not gonna get clear skies anytime soon ☹️

Sorry @Echound!! I still own a homemade 8” newtonian!  Very cool!!  

I have a question: What are those secondary bands/oval above Patagonia, During may I also saw the NOAA forecast show these above central ZA and southern Botswana/Namibia if I remember corectly. I have only seen this in NOAA's Southern Hemisphere forecasts.

What puzzles me is why the intervening proton stream is slower than the initial proton pulse we may register here on earth.  To further clarify:  A proton event seems to contain three distinct elements within it.   I have been thinking about this in the intervening hours and might be incorrect in my assumption of initial bursts.  These may be entirely electrons.  If so, I wonder if this may be the answer.  

With proton streams there is a reaction between 2 protons which creates neutrinos. This mechanism will cause some drag. and reduce the protons from the beta decay process. Solar neutrino - Wikipedia

 

Neutrinos had the same issue as you are describing; predicted and observed flux was different and was considered the solar neutrino problem for a bit. Then after years, discovered the contradiction was from the neutrino behavior. I would guess that proton streams would suffer beta decay from the neutrinos. However, within plasma, neutrinos can help stabilize and keep a plasma cloud coherent, regardless of beta decay issues.  

 

I am not sure if this is what you were asking but this is my attempt :)   Also, this was a question from October, so my apologies if this is old/answered and I missed the reply.

My guess would be it is from the Birkeland current connecting to the ring current, but it is just a guess based on what I learned about the magnetospheric currents. At least, there should be two current regions.

 

EDIT: I think it may come from higher ionisation during the local summer, and I vaguely remember such bands in the north around July. I still have to read through the OVATION model (it waits impatiently for me in one of the open cards in my browser and looks menacingly at me o.O ), maybe then I will be able to confirm it.

It is definitely pertinent and thanks for the link @Archmonoth  Merry Christmas btw.  73 ( hamspeak for best regards. Mike/Hagrid. Read article. Tnx!  Only was aware of the experiment using dry cleaning fluid at a depth of over a mile in South Dakota mine I think it was.  Cherenkov?  That surprised me although I was aware that beta particles typically produce it.  Very cool stuff!!

Why does no one seem to know what that bright yellow flame on the top left side of the Sun, which has been growing and glowing for over 5 days now, is?

 

I would have thought that it's kind of weird to have a continuous spume of plasma or whatever coming out of one region of the Sun for a whole week, myself, but then I am quite new at all this 😋

No worries! During solar max the wind speed and plasma flow is LESS. With coronal holes and such, the wind goes up and the plasma stream flows unimpeded.

The reduction in solar wind speeds near solar max would surprise me.  This would seem to require an overall smaller coronal structure. However as you know I am only learning as I go. Certainly no solar expert by any means.  Thanks again for the neutrino stuff.  Was completely unaware that Japan was involved in the study of those ghost particles until I read the Wikipedia article!  Mike 

Hi. This might be a suuuper stupid question, but I'm going to ask regardless cause I'm just so curious. I've done no research on space weather, only having picked up things that would help me to see auroras and northern lights. But I'm curious, what are those black parts in the coronagraph? I don't remember seeing them before, but I could be wrong

The fact that neutrinos seem to have been proven to travel faster than photons is indeed a very big deal @Archmonoth  and also have been proven to NOT be massless after all.  Yeah it certainly was pertinent!  Haha. Edit. Although it leads into Quantum weirdness again darnit!!  🤣🤣🤣

If you could provide an image to explain, which black parts you mean, it would help a bit. I guess you may mean either some faulty pictures with black parts or the damaged component in upper right on C3, that might have been fried.
