Here's the last frame in the sequence, minus the mp4/streaming compression. Still a tad over-exposed in my processing, but certainly much better than the default processing we see on the SOHO site.

How about the processing in https://bsky.app/profile/dermuehle.bsky.social/post/3lfpeaoorq22x? The tail structure is really unique and would be a
'textbook' example ... if we understood exactly what's going on here. ;-) Hopefully further color processing will provide some answers - and future ground-based views with sufficient elongation.

Yep, that processing is equally fantastic. It's all fantastic! 😊

Can you point me to a paper / technical website that describes the color filters of LASCO C3 (transmission curves ... and original purpose)? Sadly just learned - from the PI - that PUNCH's coronagraph has a great field of view but is broadband only: wonder how this comet would look like to it ...

Individual curves are here: https://lasco-www.nrl.navy.mil/index.php?p=content/filter/filter I could probably plot them... As for the original purpose of them... 🤷 I can ask some of the retirees what the thinking was.

PUNCH images would look a lot like C3 Clear, but with a wider fov.

Do you know why there haven't been any new LASCO images since last night?
I was hoping for comet to leave the FOV before I put up my own processing...

Looks like the servers fixed themselves. If you had something to do with it - Thanks :)
