Latest development : A time resolution of 1s / image (2000 frames = 2000 secondes of real time (remaining 8000 more seconds to process !)
Each frame of this astromovie shown at 100fps is the result of the registration of 60 original frames with registax6
Multiple use of RegiStax5 with diminishing registering zones (256 then 128 then 64) and VirtualDub to create a rather nicely aligned final movie...

This amateur observation has been useful for a scientific publication :


I have been asked a detailed step by step procedure ... here it is :)

BTW I am now redoing all the data processing (will takes days of computing) to achieve a 1s time lapse resolution ...
The goal is to have precise data ready to be used for research purposes in order to study movements and masses concerned
on this incredibly huge prominence I was lucky to be able to image !

Two nice prominences (2011/11/13) . The one of the left I nicknamed "the Dancers" and the right one "Forest of Fire" !

"The Dragon" Large solar prominence
C8 and QC Pro
Sept 4, 1999, 07H36 UT
Size of Earth at same scale :

A place with prominences as shining as the Sun itself should be watched continuously. Chances to see a flare around are important in the next minutes or hours !

On Mars 6, 2000, at 09h59 UT, I aimed my Celestron 8" SCT toward the prominence seen in the middle of  first  10H33  image.The Quickcam Pro was programmed to take automatically a serie of 5 images (separated by 500ms) every min with new version of EclipsQC software of Jean-Paul GODARD. I left everything working by itself. When I came back for checking at 10h44, I saw that a prominence had suddenly grown just a little bit outside of the left part of the image ! At 10h45, I move the field of view to have it better centered and I realized at that moment that everything was changing at an unusual fast rate !  I thought to change the interval between pictures to a few seconds instead of 1 min to have a better resolution but had no time to do it ! The next image, at 10H46, was the maximum and the next one shows already signs of disappearance ! At 10h50 , it was all but disappeared. I think this phenomena enters in the category of eruptions or flares .
The panel below resumes the event shown with more details in the above animation.Comments are welcomed !
