SAUNDER LUNAR LIGHT RAY

Initial Reports

I have imaged a Lunar Light Ray in the crater Saunder.The image was obtained on 11/19/04 @ 1:09 UT. using a Orion 5" refractor,PC-23 video camera and a Panasonic DVD recorder seeing was 4-5/10. I believe that this may be a new light ray discovery, if you have seen this ray or imaged it before let me know
Thank You, Robert Spellman - Griffith Observatory

Saunder - +151,-074: A large but lowo ring to the west of Hipparchus, eith a deep crater, N, on the wouth-east wall, here broken. On the interior are ridges, hills and some craterlets. On the north is the crater A, with its walls broken on the south and the north. To the east of A is another crater, while on both the west and east are crater chains.
