Clair obscur objects

I was just forwarded this list of clair-obscur objects, transient light/shadow phenomena. It looks to me like a great challenge list. The Atlas of the Lunar Terminator might be the ideal reference for this.

The linked list does not have the times when these phenomena would be visible. LTVT might do it at least roughly (can't expect it to show every shadow of every speck for every second in the moonth.

Any other tips on timing, locating, and exploring these objects?

Thanks for posting those links Willie!

I just spent over an hour looking at all of those LPOD links on the Wiki site, really amazing stuff! I've seen a few of them and may have some photo'd in my archives...

As far as any tips... What works for me is taking the scope out on all good moon nights and snapping a few hundred afocal shots through the eyepiece over the span of a few hours, then later go through and see if there are some interesting Clair Obscur features captured. It's somewhat tedious, but fun and rewarding to see what has been caught on digital film. No planning or predicting, just grab as much data as possible when veiwing is acceptable.

Thank you for that post Willie, as for info about them I would try A.L.P.O, The Association of Lunar & Planetary Observers and The BAA, The British Astronomical association.
