APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday September 7, 2008 (MJD 54717) ---=== OBSERVING TEAM ===--- Howard Brewington Dmitry Bizyaev ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Night is lost due to rain, clouds, and high humidity. The DIMM has a problem; see afternoon checkout. tmicro (Disconnected Sensor in M2B3 permanent error. ---=== OBSERVING LOG ===--- Afternoon: ---------- Because of the clicking noise from the DIMM's CCD mentioned in a previous log this dark-run, I (Howard) checked the problem. Unfortunately, I could not reproduce the clicking. I did, however, notice that the CCD's fan was not running. I used a Q-tip to push the fan blade, and it started turning although it seemed to run slow. And, I also discovered that I could stop the fan blade, and it would not always restart. Therefore, I shutdown the CCD electronics since a halted fan could place a heavier load on its power supply. I recommend that we replace the fan. I'm not sure if it's possible to lube the existing fan until a new fan can be installed. Please feel free to contact me if you have questions. Spectro focus was checked but not ajusted; it's set for about 12.0 degrees C. And, the collimate numbers are posted in the Problems Section.
