CDS INSTRUMENT:  A VDS software occured sometime overnight during
 non-contact period.
 JOP003 campaign was affected.  The VDS has been rebooted and the second
 part of JOP003 (the EJECT study) has been resumed.

CDS INSTRUMENT: Nominal.   nominal.  Nothing ran from 0000 to 1600 due to an 
operator error.  The plan that was developed with mk_plan on Sunday did not 
have CPT run over it and therefore was not loaded to the instrument.

CDS INSTRUMENT: SEU on primary processor at address 0x8007AFF.  Since this
address is in sequence table 11, which is a table reserved for engineering 
studies and is currently not being used, it was decided not to reboot the 
instrument.  Otherwise the instrument is nominal.

OPERATIONS ENGINEER(S): J Payne - R. Yurow            
SCIENTIST: C. Haskell / L. Wang
CDS INSTRUMENT: Nominal.   Performed CDS Engineering work to patch the GIS.  
Two additional  patches were added in addition to patch currently in the GIS. 
The purpose of the patches was to solve communication problems between the 
GIS and the CDHS.  The patching appears to have succeeded however further
testing will be required.

CDS INSTRUMENT: Due to Momentum Mgmt., instrument doors were shut. Errors
 that appeared in some studies(SYNOP) were attributed to mem errors on the sec
 processor. Sec processor was rebooted. Due to another event during the reboot
 prompted for a second reboot ofthe sec proc.

SCIENTIST:SVH Haugen 
CDS INSTRUMENT: The errors that appeared in previous studies have reappeared. 
 Due to the SERTS launch coming up, we wanted to ensure that the instrument 
 would perform nominally for the launch.  Therefore, we rebooted the primary 
 processor.  When we attempted to load the new GIS patches, we received an 
 erroneous checksum of '7C10', rather than the correct checksum, '3CE1'.
 GIS would then not accept a command to reboot from EPROM.  Therefore, we had
 no choice but to reboot the primary processor again without the new GIS 
 patches.  The old GIS patch was loaded successfully, and the instrument is 
 now ready for the launch.
CDS GROUND SYSTEM: Changed the archive disk to /cdsd2.  Also, updated PSLOAD,
 DFLOAD, and LOADPLAN to have cbaacqi 8 at the end to ensure 8 second telemetry
 is loaded to the instrument.  Edited the following raster durations:

Raster ID/Variation		previous time		updated time
	34/8			    2582		    2683
	36/27			    2043		    2145

CDS GROUND SYSTEM: nominal, changed networker configuration so that /cdsfits,
 /cdsfits2, /cdsfits3, /cdsfits4, /cdsd3-5, and /cdsr2-3 won't be backed up
 during full backup.  These disks are tar'd to a tape once they have reached
 capacity and don't need backed up again.
