CCD vs Film? Lots of time vs no patience? Alright, this is your place to discuss all the astrophotography what's and what's not. You can discuss about techniques, accessories, cameras, whatever....just make sure you also post some nice photos here too!
This is the longest filament that I have seen in Hydrogen Alpha wavelength. It covered more than 60 times the diameter of Earth. The CAK image next to it showed the magnetic field at work underneath it.
And here is the zoom-in view of that super long filament
Hi Alfred
Something very interesting happen in the filament.....not the hydra flare.
I observed.....at 9am to 9:25am.....a bright spot which indicate a flare of some
sort.Estimate c class type.Its a real surprise and more
surprising.....filament totally intact after that.
Thanks for sharing your observation. Yes, the filament was still there when I looked at it this evening. Here is the pictorial 3-day tracking summary.
Interesting to see a small tiny bright spot (near middle of filament) in the following close-up image. Wonder if it was the same one you saw in the morning.
Hi Alfred
Starting yesterday ,the thinner section of this filament starts to decay and
gaps starts to appear.Today its darkness getting
less and less and seems to be 'disappearing'.Only
the darker section is still stable.
As for the bright glowing dot.....that
indicates some kind of flare.....its not
the dot in your photos.It occur RIGHT ON
THE FILAMENT which is a total surprise.Photo
will be submitted soon. Like you I am monitoring
that filament.
Yesterday, the filament moved across the disk quite intact. No lift-off. I caught AR2282 displaying C-class fireworks.
Today, it was AR2280's (sunspot near the right limb, near the right end of the filament) for another C-class display. I imaged the Sun just before the flare. And yes, the super filament has reduced in size. Still it is a monster!!
