Sorry for the lack of updates - I have been away on vacation and tending to other tasks lately. I'll be updating again shortly. - Chris
..and the filament continues...
Harald contributed a new filament image mosaic below:
Hi
enclosed the link of the long filament from 3.8.2012.
The conditions it was very poor, I could not focus the picture precisely.

Michael Buxton managed to get some cool video of this amazing filament:
hi all
had aprox 1 hour of clear skies, just enogh time to make this movie of the giant filament
twisted flux tubes gone wild! captured at 1 minute intervals from 1635-1724. bummer the clouds rolled back in.this filament may be part active, part quiescent. looks like the end in the AR is stable, while the other side dances. perhaps the strong mag field over the AR is keeping the one end stable
Raymond posted a full disc illustrating the scale of this filament:
Look at the size of this filament. Has anyone seen one longer?
Check it out:

Have a sunny clear day !
More of the filament progression
Alan C. had a nice image of the filament from 8-4.
Taken just before 12UT with a Lunt LS-50/B1200 DMK41 and Fraunhofer F11/102mm refractor. I had wanted to film its development but had a computer crash and had to sort that before doing any more filming. More to add later but this came out quite well.
Cheers,
Alan C.
Giovanni Gabrieli also had some great images on his site:
Andy Devey captured some great video of the progression as well.
Hi Guys
I was watching for this one but missed the front end of the event as I was distracted with the Olympics events on TV.
Here is a substantive part of the event from 12:18 to 13:18UT in grade 2 seeing conditions and was at 0.8m focal length with PST due to scale of this event. Here I have animated every 3 minute frames.
Hope you find it useful
Regards
Andy

Wes Higgins - Solar Snake
"Hi,
Imaged 08-02-12
Giant Filament that looks like a snake, not so good seeing today."
Solar images for 8-2-12
Bart Declercq Posted some Hi-res Sunspot images:
"Yesterday, I was very lucky with the seeing, allowing me to increase magnification considerably. Using the Basler Ace a1300 camera (3.6µm pixels) at 6 meter focal length and having a full-aperture solar filter on the 30cm Newton gave me considerable resolution, as you can see in the attached images."
Harald Paleske has some more outstanding images, this time of a filament he called "Mouth of hell".
"31.07. :
The conditions was very poor, but the objects was very interesting. Like a fire tongue the gas from the open chromosphere climbs up.
It looks in such a way as if the devil sticked out his tongue short from the hell."
CN Member AstroPaolo posted some Hi-Res Mosaic's:
"
In those days (July 28-30) the Sun was spectacular, full of prominences and details on the disc.
Here the mosaics I could build with what I captured, the seeing was not so good but atleast the sky was not cloudy or foggy.
I also attached a single image of 26, not yet publushed."
Mouth of hell
Harald posted this image he calls "The mouth of hell".. Quite fitting given his description..

Ellerman Bomb by CN member jpb30
Even in bad seeing - Forum member jpb30 posted some great images of an Ellerman Bomb in his latest images
Hello
i present to you somes pictures taken the 31th with AP155
a Ellermann Bomb is present on Ar11530

Wes Higgins - Improving Resolution
Wes went about using some different methods in his workflow to produce the jaw dropping image. Make sure to click through to the full size version...
"I did two things different in processing this image than I had done before.
1. I used the program PIPP for frame selection (I think it does a better job than Registax or Avistack).
2. I used some solar processing tips that Alan Friedman gave me."
Andy Devey - Prom Lift off 7-31-12
A few folks noticed a large prominence rapidly lifting off the surface, Andy was lucky enough to capture it below:
"Hi Guys the scale of this one caught me out I was initially at 1.6m focal length with PST so had do do some extra work here on the first still but here is from 08:42 to 09:00UT I will post the other sequence later
Hope you find this useful

Dmitry Makolkin - Solar Continuum
Dmitri made excellent use of good seeing conditions to grab some incredible white light detail mages. He writes:
"It was the best daytime seeing I had in this summer season. Fresh air from the necessary direction moved hot air from the roof away from the scope so I could use Barlow 1.4x
Resulting scale is 0.26"/pixel."

Scope: TAL-250K Barlow - 1.4x
