LUNASCAN  MISSION REPORT:   Session # 20150427 – 02 - 84

========================================================================================================

1. QUALCOM SYNOPSIS:

Mission #2 for 2015 was successful and AOT was at 19:38:11 Quad Time/7:38:11 local. The duration of the mission was 1 hour 25 minutes 10 seconds, mission terminated at 21:02 Q. WWV was good on all recordings once the problem was realized. The aluminum shield of the trailer with the Sennheiser receiver inside was the culprit, so opening the door wider helped. Reception still varied however. At 20:10:43 there was a good WWV fix with a data stream and another fix at 20:12:04 = 00:40:22 EL =0108m00s CUT time fix.

Cam 4/SSI camera had good images. Elapsed 00:06:19 Good Tycho, etc. 00:11:51 Mons Piton, etc, Apennines. At  00:13:18 eastern crater rim on Copernicus  illuminated by rising sun. Crater interior not illuminated but complete rim was lit during the mission.

EOM at 21:02:00 Q
