AUGUST 7, 1996 -- 210

INSTRUMENT STATUS:  nominal.
                    Two studies, PY24W/v5 (Prominence Temperature Diag.)
                    were not run due to an accidentally deleted VDS window
                    table.  The table was deleted while manually editing the
                    LTB file and associated CVT files in order to correct
                    for a previous switch in table indexes performed on DOY
                    209.  This switch was done to allow a plan which was
                    created by CPT with the /NEW switch set to be uploaded
                    without aborting the studie(s) which were currently 
                    running.

AUGUST 15, 1996 -- 218

INSTRUMENT STATUS:  nominal  
CDS GROUND SYSTEM:  nominal, changed raster 11/7 to 563 seconds due to a 
		    problem seen with study 4186.  See e-mail for all of the 
		    info.  Basically, FSUN ran way over and the ops had
		    to take more time than allotted to reach their positions.
		    Stein caught the problem by analysing the data from 
		    study 4186.  Imported studies deepsp_1 and o_fflows_10.

AUGUST 20, 1996 -- 223

INSTRUMENT STATUS:  Investigation into a strange occurrence in which a series
	            of untagged studies did not run.  The next time-tagged 
		    study ran properly at 1300, but after the SYNOP at 0630,
		    the untagged studies after it did not run until the 1300
   		    time-tagged study. Also found that a time-tagged study at
		    1900 did not run, either.  This is very strange since a 
		    replay through STM showed the commands as being loaded
	            properly.  Ran cpt/update to the instrument for
		    changes made to ops_ltheta and ops_lphi in the state DB.
  
CDS GROUND SYSTEM:  nominal, updated raster 79v2 duration from 691 to 725.  
		    Imported the follwing studies:  dynhel1_2, o_netw1, 
		    o_netw2, and o_netw3.

AUGUST 21, 1996 -- 224

INSTRUMENT STATUS:  nominal, previous day's investigation turned up nothing, 
		    so the problem just seems to be an unexplained anomaly. 
	            CPT was run with /new, and these problems have not been 
	            seen.

AUGUST 23, 1996 -- 226

INSTRUMENT STATUS:  nominal, changed pointing on study NSGSCAN1/v1 to run at
		    Aug 24 1:51 at the request of the scientist.  Pointing
                    was changed by manually editing the CVT file series_57.dt
                    and inserting the new OPS pointing.  This file was then
                    uplinked to the instrument.

CDS GROUND SYSTEM:  nominal, changed the state database y-centering parameter
		    and loaded update to the instrument.

INSTRUMENT STATUS:  Detector 1 trip during GIS study @1425 UT today.  Analysis
		    showed no unusual count rates, currents, or voltages.  The 
		    raw count rate peaked at around 2200 before tripping, the 
		    voltage was around 4.05 kV and the current at 22.8 uA.  The
		    detector was reset @1509 UT while the GIS study was still
	            running.

CDS GROUND SYSTEM:  nominal.  Changed the following raster durations:
		    31/v3 from 315 to 280
		    31/v4 from 315 to 280

INSTRUMENT STATUS:  Instrument anomally occured at aproximately 13:26 UT
		    when a CDHS Macro Error was detected.  This error occured
		    when series ID 3860 (table 41) attempted to start series
                    ID 3861 (table 38).  Table 38 at the time contained 
                    series ID 3845, which caused a Macro Series ID error to
                    be generated.  The reason table 38 contained the wrong  
                    series is that series ID 3845 was mistakenly loaded into
                    table 38 by the operater the night before.  Once the
                    macro error occured, the processing of study G2AL/v1
		    halted and the CDS entered READY_BOTH mode.  The CDS 
                    remained in this state until the study LIMB/v6 was started
                    manually at 16:04 UT.  Also lost was study GEAST/v1.
