2013 June 21 Sun - spectacular eruption of AR11777-complete

PTS

The small AR on the E limb from yesterday is now designated AR11777.  This AR displays a spectacular eruption starting at about 10:38.
These images are affected greatly by the intervening clouds, and there is virtually no control on the brightness.
Changes are visibly visible by the second.
The shoot-up eruption virtually subsides by about 11:16, while the flares continues.  
A second eruption is observed from close to the spot around 11:24.  Unfortunately observation has to stop before 11:30 by the threat of black clouds.

I try to re-start observation after lunch.  However, when my equipment is ready again, the sky is virtually covered by clouds and only a few snap shots are capture.  By then, even the flares have subsided.

Telescope: AP Starfire EDT 155 mm f/9.
stopped to 50 mm for disc images, with 4X telecentric lens (f/36) for closeups
filter: Solar Spectrum SO1.5/0.3A with CERF prefilter
Camera: Imperx 4M15
North is up, and east to the left

This was really great.  Where Can I see this video?
Could you tell me some webpage or books to read about the sun?

There is no video yet.
As you know, I capture still images only.
For books on the Sun, I'll send you a list tomorrow (I've gone home early today).  What level of books are your interested in?

Thank you very much.
Is there any homepage sun info?

Do you mean websites on the Sun?
There are indeed plenty of them:

Oh! thank you very much.  You are so kind, let me bookmark all of them.
BTW, is this good?

I have not used SBIG spectrometers, thus I cannot comment.

You can check this website:

http://www.astrosurf.com/buil/spectrographs.htm

for more information.

I have the LHIRES III (spectral resolution 17000), the Star Analyser (resolution about 200) and waiting for the delivery of ALPY 600 (resolution 600).
