Comet Elenin in STEREO H1B (August 19 and 20)
I've done something different here. I've zoomed and cropped these images of Comet Elenin from the STEREO H1B imager in order to capture the tail of Elenin. Presenting the images this way makes the tail easier to see. On the 19th a solar flare passed over Elenin and the tail flared as well and was twisted about. The weird white patches in the image of the 19th are artefacts of the background subtraction process I use. It looks better in animation. Here's the AVI animation of the August 19 images (1 Mb) and the AVI animation of the August 20 images (1 Mb).
Comet Al has a better animation of the August 19 event here.
Congratulations on your blog, and your information always updated.
I wanted to ask about this: ...
"possibly STEREO's COR2 coronagraph as well between August 20 and September 1"
Have you an image?
I'm a little confused, I rinse it be if your COR2 In what I look for?
