CDS INSTRUMENT:  Slit motor went into high temperature alarm at 1930 UT.  The cause is being 
 investigated.  The temperature climbed to 43 degrees from 28 degrees, and then decresed back down 
 to 30 degrees within a matter of 10 minutes.   Plots of BTM18 were printed out.  The rise in temperature was seen in conjunction with a 
 ICAL 1 study ending and FULLCCD beginning.  The slit moved from 2 to 4 during this transition.

CDS INSTRUMENT:  BTM18 (slit motor temperature) went into high alarm again at 1113 UT.  This was a 
 transition between POBS1_1 and POBS2_1.  The cause is again being investigated.
CDS GROUND SYSTEM:  Problems with the backup system led to the operators to  shutdown CDS8.  When
 CDS8 was brought back, the licensing manager for IDL did not execute.  It was finally found that the
 licensing manager had to be manually executed.  Once that was done, everything was fine.  Also, imported the following studies to EOF:  fillfacn_14, 
ffarr10_8, tranreg_12, and nfctr_9.

CDS INSTRUMENT: nominal, still investigating the SYNOP occurence.  The resolution on the detector 1
 trip has been sent by E. Breeveld.  Essentially, the Fe IX/X line is very bright and the GIS 
 study was using slit 6.   This caused the count rate for detector 1 to exceed the limit of 25,000, 
 and therefore tripped.  The SYNOP occurence is also being investigated.  There have been a couple
 of data files missing on the CDs.  The EOF has been notified.  Also, we had a problem with CPT 
 giving a duplicate CDHS ID to two seperate studies.  The problem was noticed while trying to run 
 fitsgen on the data.  Bill has corrected the problem by editing the database.

SCIENTIST: J. Klimchuk
CDS INSTRUMENT: Performed engineering work to help determine the cause of the high slit motor temperature.
 The plan was to nudge the ops over the home position in an attempt to smooth any debris that may 
 have accumulated around the slit's home position.  Current theory is that the slit's home position
 may have some debris around the home position therefore inhibiting the encoder from detecting the 
 home position.  
CDS GROUND SYSTEM: Imported the following studies to the EOF:  loops_1_1, loops_2_4, and loops_3_1.

SCIENTIST: J. Klimchuk
CDS INSTRUMENT: nominal, may have uncovered the reason for the SYNOP problem.  A recovery of the 
 series table files from the 10, 11, and 12th of October showed that the ops commands included in the
 file moved the ops from (0,880) to (0,1760) and then left them there.  So, the instrument did what
 it was supposed to do, but it appears a CPT problem.

CDS INSTRUMENT: The CDS Instrument encountered an SEU on the secondary processor at ~17:30 UT.  At
 about 17:54 UT the entire CDS crashed during a command upload.  The first indication of the anomaly
 was the failure of the instrument to acknowlege bit on the OBDH bus in response to commands.  Latter
 investigation showed that the instrument was refuseing to send telemetry or respond to commands.  
 The CDS was brought back to SNOOZE mode by sending the commands cccrsetn and czcprpu1.  Latter the 
 instrument was brought up READY_BOTH and the secondary processor was reenabled.  The instrument 
 remains in READY_BOTH with all subsystems powered but no high voltages enabled in the GIS.  The 
 CDS will be recovered to a nominal state tommorow.  No science is currently being run.

COMMENTS: While bringing the instrument up to READY_BOTH, the study counter was accidently set to

CDS INSTRUMENT: The slit motor temperature (BTM18) went into red alarm twice today.  The first 
 occurence of the anomaly happened at 17:44 UT.  This corresponds to the start of the GIS Spectral
 Atlas, SPECT_V1.  The second time it occured was at 20:59 UT, probably during the transition from
 slit 1 to slit 6, which was used by the next study -- NFFAST1.  In addition, the telemetry point
 BIEG+5V was at 382.10 mA today.  Although still within its limits, this is ~50 mA higher then where
 it usually sits.  This could be due to tho fact that the GIS was loading a lookup table when this
 was observered.  Latter it dropped down to its usual value.  Otherwise the instrument was 
 nominal.

COMMENTS: The slit motor temperature anomalies on DOY 300 were resolved.  Each one was due
 to the operator misunderstanding what the red and yellow limits were for telemetry point
 BTM18.  

 J. PAYNE confirms that the increase in BIEG+5V was due to the heavy processing needed
 for the GIS to load look up tables.  

 No fits files were generated on DOY 301 due to S/C attitude data being unavailable.  All
 fits files for that day have now been processed.
