September 1, 1996 -- 245

INSTRUMENT STATUS:  nominal	
CDS GROUND SYSTEM:  nominal
PLANNING	 :        

=====

September 2, 1996 -- 246

INSTRUMENT STATUS:  nominal	
CDS GROUND SYSTEM:  Imported the following studies from RAL:  BURST_1,
		    NFFAST1_1, NFFAST2_1, and UVCS44W_12.  Changed the
                    duration of UVCS44W_12 from 6312 s to 7000 s.
PLANNING	 :        

=====

September 3, 1996 -- 247

INSTRUMENT STATUS:  Secondary event detected again.  Event was later 
		    overwritten.
CDS GROUND SYSTEM:  nominal

INSTRUMENT STATUS:  nominal	
CDS GROUND SYSTEM:  nominal
PLANNING	 :        

=====

September 6, 1996 -- 250

INSTRUMENT STATUS: nominal   	
CDS GROUND SYSTEM: changed quicklook disk to /cdsr1.  In order to automate
		   feature tracking, placed the following lines into LOADPLAN
		   to ensure that the feature tracking parameters are loaded:

			@ARGV=("today.dt");
			do 'CB2FEAT'; 

		   Detector 1 tripped again.  Detector was reset and was okay.

INSTRUMENT STATUS: nominal
CDS GROUND SYSTEM: nominal 
PLANNING	 :        

=====

September 9, 1996 -- 253

INSTRUMENT STATUS:  nominal 
CDS GROUND SYSTEM:  nominal, EGSE crashed for some unknown reason.  Then, the 
		    connection between CDS and EOF would not terminate.  After
		    logging out and back in again, the problem cleared up.  
		    .REL files from EOF were ftp'd to recover the lost data.
PLANNING	 :        

=====

September 10, 1996 -- 254

INSTRUMENT STATUS:  nominal
CDS GROUND SYSTEM:  nominal, changed the HV trip on detector 1 to 26 uA from
		    25 uA.  Change also included in GIS_SETUP.
PLANNING	 :

September 11, 1996 -- 255

INSTRUMENT STATUS:  ***  Closed CDS doors for momentum management at 17:00 UT *
		    **
CDS GROUND SYSTEM:  nominal
PLANNING	 :        

=====

September 12, 1996 -- 256

INSTRUMENT STATUS:  nominal, doors reopened at 21:30 UT.	
CDS GROUND SYSTEM:  nominal
PLANNING	 :

September 13, 1996 -- 257

INSTRUMENT STATUS:  nominal
CDS GROUND SYSTEM:  nominal
PLANNING	 :        

=====

September 14, 1996 -- 258

INSTRUMENT STATUS:  nominal, 5 studies between 0000 and 0730 were run with 
		    slit 6 instead of slit 4 due to an error in which the slit
		    was  manually set to 6 before the studies were run and was
		    not set back to slit 4.  The instrument assumes the slit
		    to be at 4 and continued to run the studies as though that
	 	    were the case.   
CDS GROUND SYSTEM:  nominal
PLANNING	 :        

=====

September 15, 1996 -- 259

INSTRUMENT STATUS:  Primary SEU at 8001cdf4 - compression module.  Rebooted 
		    CDHS beginning at 17:15 UT.  The GIS software patch was
	            not recovered and had to be reloaded.  The reload was
		    successful.  
CDS GROUND SYSTEM:  nominal, /cdsfits4 at 96%, moved some fits files to /user1/
		    master/fits_temp  for temporary storage.
PLANNING	 :

INSTRUMENT STATUS:  nominal
CDS GROUND SYSTEM:  nominal
PLANNING	 :        

=====

September 17, 1996 -- 261

INSTRUMENT STATUS:  nominal, ran the lube study at 17:00 UT.
CDS GROUND SYSTEM:  nominal
PLANNING	 :        

=====

September 18, 1996 -- 262

INSTRUMENT STATUS:  nominal
CDS GROUND SYSTEM:  nominal, imported study demst_1 into the EOF, software
		    update performed at 19:00 UT.
PLANNING	 :        

=====

September 19, 1996 -- 263

INSTRUMENT STATUS:  nominal, very degraded data from 0000 to 0800 last night.
		    Data was recorded at the station, so a retransmission is
		    necessary.  Most fits files created during those times
		    are worthless.  Once retransmission is done, we will redo
		    the fits files for that data.  Secondary event recorded at
		    1750 UT.  Rebooted at 1830 UT with no problems.  CDS now
		    nominal.
CDS GROUND SYSTEM:  nominal, /cdsfits4 at 96% again.  May have to move more 
		    files tomorrow.
PLANNING	 :        

=====

September 20, 1996 -- 264

INSTRUMENT STATUS:  nominal	
CDS GROUND SYSTEM:  Initial command load failed due to duplicate request ID
		    being generated by the IWS.  This seemed to be due to
		    the IWS crashing while still connected for commanding.  It
                    did not store the last request ID it had used.  A retry
		    of the command load succeeded.
PLANNING	 :        

=====

September 21, 1996 -- 265

INSTRUMENT STATUS:  CB2FTI (Feature Tracking Interval) error generated by
		    MCU backup.  This was due to the duty scientist forgetting
		    to run PREPARE_FT.  No action taken except to run 
		    CLEAR_ERRORS. 	
CDS GROUND SYSTEM:  XCPT is reporting no entries in the SCI_FLAG database.  In
		    addition XCPT compiled command loads for the wrong time
		    period when called from MK_PLAN.  Stopping XCPT while doing
		    this at one point caused an LTB file to be erased.  This
		    was only discovered when the command load was attempted.
		    The LTB file had to be manually reconstructed, by this
		    time it was to late to run the first study - SYNOP.
PLANNING	 :        

=====

September 22, 1996 -- 266

INSTRUMENT STATUS:  CB2FTI (Feature Tracking Interval) error generated by
		    MCU backup.  This was due to the duty scientist forgetting
		    to run PREPARE_FT.  No action taken except to run
		    CLEAR_ERRORS.
CDS GROUND SYSTEM:  Nominal

=====

September 24, 1996 -- 268

INSTRUMENT STATUS: nominal
CDS GROUND SYSTEM: Transition to IDL version 4.  Mounted a new (temporary) 
		   disk on cdsa1 called cdsfits5.  When our new disks arrive,
		   we will be transitioning to the new disks.
PLANNING	 :        

=====

September 25, 1996 -- 269

INSTRUMENT STATUS: nominal
CDS GROUND SYSTEM: nominal, for some reason CPT twice incorrectly included the
		   wrong times for a plan.  There was a timetagged study which
		   just crossed the time boundary, and when CPT was run, it 
                   included that study in the plan.  CPT was rerun twice, and 
		   finally the plan had to be modified as to make the 
		   timetagged study which crossed the boundary and untagged
		   study.  CPT then worked fine.
PLANNING	 :        

=====

September 26, 1996 -- 270

INSTRUMENT STATUS:  No studies ran last night due to a sequence ID error.  The
		    reason was due to a multiple runs of CPT without using a
		    /new.  As a result, a sequence ID error was reported and 
		    the instrument ran nothing between 0000 UT and 1722 UT.  
		    CPT was run with a /new and a plan was loaded to start at
		    1722 UT.

CDS GROUND SYSTEM:  nominal, Some GIS studies had an icorrect GSET ID of -1 in 
		    the catalog entry.  Studies were identified and edited to 
	            correct the errors in the catalog.  After running an IDL
		    routine on the catalog, it was discovered that a 16
		    other studies were missing either the SCI_OBJ or the 
		    SCI_SPEC.  These were also edited to correct the errors.
	            These studies will be reprocessed through the CDROMs at 
		    a later time. 

		    Also, changed the archive disk to /cdsd5.
