Laboratorium Solaris: Firedance
Tiny crop from the Eastern limb of the Sun where the things were happening during March 20th eclipse.
To watch the action take a look on Original size image (animated GIF).
Main window shows the final frame with the Moon getting where :)
The sequence spans about one hour (32 frames each 2 minutes) from the beginning of the eclipse at 12:12 to 13:23 GMT+4 - slightly past maximum as seen from Moscow.
Images were prepared as describe here, cropped, rotated, masked and blended for contrast enchancement, upscaled and saved as animated GIF. Flickr tends to stop playback of low framerate videos near the middle of the movie so GIF again.
Note: well, dark frame substraction is needed if faint stuff is to be pulled out.
Note 2: I have used two masks - one with gamma>1 for the disk and another with lowered white-point for proms. They were used for all frames. And the images had accumulated some shift due to imperfect alignment - hence the dark band along the limb. For top precision each frame should be masked individually. Next time I'll try to employ PS actions for this.
Upd. 23.03.2015: I have replaced the original image with more precisely aligned version.
