What is this coming out of AR2192 please?

[Iainp]

Hi all, First time posting; I tried earlier today but obviously did not succeed! I bought a Lunt 80mm months ago but moved house and it stayed in its box until a few days ago when I read about AR2192.  Here's my best image from 2 days of frantic experimentation with the scope between clouds (UK) and my colour one-shot camera, the Skyris 618C .  Can someone tell me what is coming out of the spot? A filament? It seemed to be a very short lived event. Thank you, Iain

possibly this

A massive solar eruption on 26 October was the sixth large flare since 19 October, all emanating from one gigantic sunspot called AR 12192. Measuring 129,000 kilometres across, it's the largest sunspot since 1990. For comparison, that's a spot 10 times the diameter of Earth

Good shot for a colour cam. The plume of material apparently being ejected from the active region is called a filament.

[Uplooker]

It is a filament. Am  I correct in thinking that it is a filament as it is on the surface of the sun but will then become a prominence once it makes it round to the limb of the sun?

I had a little play with your image - there is quite a bit more detail in there (Hope you don't mind!):

[Iainp]

Thank you!

It shows up on the 2 sets of images I took immediately following this one, then disappears. I've put the 3 frames together as a timelapse here:

Nice detail. Thanks. I've got 200 more to send to you for processing now ;-)

That would be correct.

[Pete Presland]

it is a superb capture, you should be very pleased with that one. not sure about the red colour but that is just personnal taste.

[Iainp]

Many thanks Pete.  The red is  the "real" colour produced by the colour camera rather than something I've chosen!  I'm still experimenting with desaturating the images then "rebuilding" to a more pleasing palate, but so far, I've ended up with quite muddy and unsatisfying results.  A steep learning curve ahead...

I'm fairly certain this was a jet of material caused by a C6 flare on the 28th.

As the flare rose a this jet came out and then lingered. I'm not particularly certain that this feature is called a jet but they are cool.

A surge prominence seems to be the correct terminology.

[GreatAttractor]

Correct me if I'm wrong, but I believe a dark jet like this ejected from an active region is a surge; while a filament is a longer-lived, quiescent feature not above a sunspot.

[GreatAttractor]

Beat me to it, Jarrod

[JB80]

A Prom and a Fil are basically the same thing but it's just their location on the solar disc that classifies them. If it is on the edge of the disc and protruding it's a Prom and if it's on the face it's a Fil.

I believe.

For example that huge filament approaching the limb now will once it has broken the edge be called a Filaprom and eventually rotate into a Prominence.

Again, I am led to believe.

If you scroll down to the solar prominence classification you will see this is a classical 'G'

I read too many books, I think that is stage 2 of solar addiction

Nice read. I like imaging, could i explain whats what in my images......no. clouds around and nows a good time to learn

That's a fabulous link Alexandra, need to spend a few hours reading through it :-)
