A blog about a system to determine terrestrial albedo by earthshine observations. Feasible thanks to sheer determination.

Moon movie with halo

Showcase images and animationsPosted by Chris Flynn Mar 23, 2012 04:34AM
Movie shows 9 images of the moon centered on a particular crater on the bright side.

Greyscale is "minmax" + "log" in DS9.

The halo light looks very stable around the bright side edge. Naively at least, it appears as if the determinations of alpha (power law fall off of scattered light at large angle) should be very stable.

In this time sequence one can see the terminator changing slightly -- certain features brighten, others dim - - especially crater walls and mountains.

Movie is here:

play it with e.g. mplayer Vmovie.mpeg -loop 0
for a continuous loop.
