06/01/2010 03:53:02 DTR3A NOAA-15's DTR3A was re-stacked from 03:43:00-03:53:02 UTC on JDay 152 as part of data gap testing.
01/25/2010 10:00:00 DTR3A DTR3A removed from the schedules for ~1 month to see if data gaps in NOAA-15's GAC data dissipate.
11/29/2009 10:45:13 XSU1 Cleared data path configuration to STX4.
11/29/2009 10:45:13 XSU1 Cross-strapped AIP data stream to STX4.
11/29/2009 10:45:13 AIP1 Configured STX4 for AIP for a close approach call-up pass at McMurdo.
11/04/2005 16:57:00 DTR3A Stop Rec 3A
