We had a few minor problems: primary latches did not latch on first attempt when mounting Cartridge 2 and Cartridge 5; HVAC control box downstairs on the south wall was loose and it powered off when we were trying to increase the pressure in the enclosure for dust. See the log. ---=== OBSERVING LOG ===--- Afternoon: --------- The telescope has been checked and prepared for observations and all systems are functioning properly. The collimation is set for 4C. Did not begin ventilation as early as we could have because of high wind (gusts up to 40 mph) and high dust (1.0um counts up to 4k). 00:45Z - Began ventilation. Doors and louvers open, fans on. Night: ----- 01:17Z - We had a minor problem with the primary latches not latching while mounting Cartridge 2. We removed Cartridge 5 and raised Cartridge 2 to be mounted and when we pushed the primary latch button the Air On LED lit up and the air sounded as though it were flowing properly, but the latches did not respond. We lowered Cartridge 2 about halfway and then raised it back up and tried again and every thing worked as it should. Nothing was out of spec with respect to the height or force readings on the handpaddle (force was 1377 both times) during both attempts at mounting the cartridge. 02:37Z - Doors and louvers closed and fans off because of rising humidity (>50%) and high dust counts (1.0um counts >8k). 03:05Z - We checked the dust count within the enclosure using the MetOne Laser Particle Counter. The counter is set for 0.5um particles and we could not locate the instructions to change this setting to 1.0um. The counter read about 15k for the 0.5um count within the enclosure. 03:12Z - Dust counts growing (1.0um counts >9k), so we decided to increase the pressure inside of the enclosure as per the instructions on the HVAC control box located downstairs on the south wall. As we began the procedure, the control panel powered off. We noticed that pushing the control box back up against the wall would turn it back on and subsequently releasing it would shut it off. Two screws that lock the control panel to the control box were disconnected, so we proceeded to lock them down at which point the control panel remained powered on and the procedure could be completed. After the screws were tightened and the panel powered back on, it went through a self-awareness check and we noticed that the date and time are incorrect and need to be corrected. We recommend that the unit be inspected and checked out since we found it in an atypical state. 03:48Z - Dust counts increased to >10k. We moved the telescope to an altitude of 6 degrees and turned off the recirulation fans in order to prevent dust from accumulating on the mirrors. 08:09Z - Began ventilation again. Doors and louvers opened, fans on. Dust counts down to 3100 and falling and humidity down to 17%. 09:30Z - When trying to mount Cartridge 5, we encountered the same problem as before with the primary latches. Again, nothing was out of spec with respect to force or height. Lowering the cartridge halfway and then raising it back up was again the temporary solution. 09:38Z - Enclosure off. 09:51Z - Cartridge 5, plate 2560, seguefaint149. Needed an FK5 and the spiral patterning to acquire the field. Pre-calib. 2X25-minute exposures; 1X20-minute exposure. Post-calib. Seeing: 1.5" SoS warned of whopping fiber errors. 11:45Z - Enclosure on. endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 6775 22:12Z 22:33Z 100 O -119.04 -113.69 50 ignore ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot az el --------------------------------------------------------------------------- ---=== LTMATCH RESULTS ===--- Run Field nFields alt az nGood rowMean rowSig colMean colSig rot ------------------------------------------------------------------------ ---=== SPECTROSCOPY DATA SUMMARY ===--- Summary Checked (y/n): yes QA Procedures Done (y/n): yes; checked bias (44166), flat (44167), arc (44168), science (44169) for Cartridge 5, plate 2560, seguefaint149.
