APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday April 22, 2008 (MJD 54579) ---=== OBSERVING TEAM ===--- Night: Dmitry Bizyaev Howard Brewington Swing: Kaike Pan ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We did imager cals all night because of clouds. ---=== OBSERVING LOG ===--- Afternoon: ----------- All systems checked and working properly. We had two minor problem: 1) Instrument lift refused to go down: when changing cartridge, lift cart refused to go down when the cartridge was unmounted. On the MCP interlock, instrument_lift was up in red. I noticed that MCP showed that SP1 door was closed (it must be open because a cartridge was in place). So I clicked on door open, then and MCP showed it was open, and I was able to move the cartridge down. 2)Rotator abortion: When I tried to move rotator from 0 degree to 15 degree from tcc for fiducial cross check, it aborted. Then I did axis initialization, things looked fine. But another attempt failed again with the same rottor abortion. So tried to move the ratator from MCP, andd was able to do so. Then I went back to tcc, I was able to move it this time. The only thing that I noticed was a very large error associated with rotator before the movement attempt from MCP. Night: ------- 01:35Z Doors and louvers closed, fans off. 01:38Z We had clouds at sunset, so we setup and started imager cals. 02:20Z getQeCCD Red Dewar-5, run-number 7456, frame 02 to frame 48. 03:06Z Evening twilight 04:14Z Moonrise 04:40Z getQeCCD Red Dewar-6, run-number 7456, frame 49 to frame 96. We got the following error but the image looked okay. WARNING! We receive flux too low even after a retry!
