LUNASCAN  MISSION REPORT:   Session # 20150821 – 06 - 88

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

1. QUALCOM SYNOPSIS:

Mission #88 had great imaging and good WWV (once the the signal problem - door issue was resolved). Not sure when the CA (contrast artifact) began, whether this year or earlier, but imaging was still good in spite of it. The cause is still being sought.

Acquisition Of Target (AOT) was at 19:52:30 Quad or 7:52:30 PM and mission was terminated at 21:21:50 Quad or 9:21:50 PM. Duration of mission was 1 hour 29 minutes and 30 seconds.
