LUNASCAN MISSION REPORT:   Session # 20140831 - 03

DATE-TIME: August 31. 2014 20:11:13 Q

MISSION TYPE: Routine Primary Targets: Theophilus, Mare Crisium

Colongitude:    192.1° Phase:    252.9° Lunation:    23.01 days Illumination:    35.3%

SYNOPSIS: BOS 19:40:31 Q = 0h40m CUT EOM 1m31s elapsed or 21:11 Q Mission #3 for LIMO and shakedown. Some problems encountered but by 13 minutes good images were coming in, in spite of the low elevation and obstructions introducing false colors and distortions in brief episodes. Concerned about the computer difficulty in booting up the SSI camera. Next mission may tell the tale. Biggest problem was LOS of WWV on the SSI camera recording. Excellent WWV on all other recordings. Might have been corrected by Mission #4. No anomalies, TLPs or fastwalkers observed.
