LOGBOOK - FRANCISQUITO OBSERVATORY All times and dates are UTC except as noted. Local time is currently UTC -8hrs (Pacific Standard Time).
2005.02.22 - OBSERVATORY STATUS REPORT The Francisquito Observatory has been off-line since early December 2004. Heavy rain caused minor damage to the transformers which convert AC current to the DC current required by the telescope control systems. Due to continued, almost daily rainfall the transformers have not been repaired. An additional, more serious problem will also need to be corrected: while installing an OS security patch on the main observatory computer there was a complete loss of data and installed software on the main hard drive. Consequently, the software installation, calibration, and testing done during the observatory's commissioning period will need to be repeated - in itself a multi-week series of tasks. Progress updates on observatory rehabilitation will be posted from time to time. 2004.12.04 -REPLACED POWER SUPPLY UNIT FOR TELESCOPE DRIVE; INSTRUMENTATION POWER-UP AT 01:15; NEOCP OBJECTS 4W128B0, 6C3001 PROGRAMMED AS TARGETS; IMAGE ACQUISITION SCRIPT INITIATED AT 01:45. -OBSERVATORY CLOSED AT 12:00; 3 PTS ASTROMETRY OBTAINED FOR 4W128B0, SENT TO MPC IN BATCH 04122; 3 PTS ASTROMETRY OBTAINED FOR 6C3001, SENT TO MPC IN BATCH 04123. 2004.12.03 -OBSERVATORY CLOSED PENDING REPLACEMENT OF TELESCOPE DRIVE'S POWER SUPPLY. 2004.12.02 -INSTRUMENTATION POWER-UP AT 01:30; PHAs 2004VA AND 2004VC17 PROGRAMMED AS TARGETS; MODERATE GUSTY WINDS CAUSED POOR SEEING AND DIFFICULTY BRING IMAGER INTO FOCUS; IMAGE ACQUISITION SCRIPT INITIATED AT 03:00. -OBSERVATORY CLOSED AT 12:00; POWER SUPPLY TO TELESCOPE DRIVE TRIPPED OUT SEVERAL TIMES WHILE TRYING TO SHUT DOWN, POWER SUPPLY TO BE REMOVED & REPLACED. -3 POINTS ASTROMETRY OBTAINED FOR ALL TARGETS, SENT TO MPC IN BATCH 04121. 2004.12.01 -OBSERVATORY CLOSED DUE TO OVERCAST SKY AND/OR HIGH WIND. 2004.11.30 -INSTRUMENTATION POWER-UP AT 01:15; PHA 2004VA AND FRANCISQUITO MAIN BELT DISCOVERY 2004PC27 PROGRAMMED AS TARGETS; POOR SEEING CONDITIONS (DUE TO GUSTY WINDS) CAUSED ABORT OF AUTO-FOCUS PROCEDURE; IMAGER CCD INITIALLY COOLED TO -30DEG C BUT WARMED TO -20DEG C AFTER ICE & FROST FORMED ON CCD WINDOW; IMAGE ACQUISITION SCRIPT INITIATED AT 01:45. -OBSERVATORY CLOSED AT 12:00, SKY CLEAR; TEMPERATURE-COMPENSATING FOCUSER REACHED TRAVEL LIMITS DUE TO UNUSUALLY LOW TEMPERATURE (-1DEG C); -3 POINTS ASTROMETRY OBTAINED FOR PHA 2004VA AND MAIN BELT OBJECTS 03526(Schleicher), 08916(1996CC); NO ASTROMETRY OBTAINED FOR 2004PC27 DUE TO POOR SEEING AND/OR EXPECTED FAINTNESS (~MAG. 20.1); ASTROMETRY SENT TO MPC IN BATCH 04120. 2004.11.24 TO 2004.11.29 -OBSERVATORY CLOSED DUE TO OVERCAST SKY AND/OR HIGH WIND. 2004.11.23 -INSTRUMENTATION POWER-UP AT 01:30; PHA 2004VB PROGRAMMED AS TARGET; DATA COMM.
