APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday June 23, 2007 (MJD 54275) ---=== OBSERVING TEAM ===--- Audrey Simmons Kaike Pan Suvrath Mahadevan (UF) Justin Crepp (UF) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- The skies played games with us all night. We opened at sunset to partly cloudy skies, but struggled to obtain any signal on cart 9 (clouds, radar, bad seeing). We closed and completed monthly checkout tasks. We reopened to somewhat clear skies around 1am and were able to finish cart 2, plate (2564) even with a significant amount of extra signal. Shakeup summary: 1) Imager bias/flats were taken and checked. 2) Powered down DIMM. 3) sdssProcedures V2_34 was checked and verified, including Dan's new procedure for the emergency closing system. 4) Spectro dithered flats were taken last night. 5) Jon's test on IOP will be left to ET time since the test version IOP was not ready yet. 6) We fought for 2 hours on Jim's SEGUE bright plate test. The weather (bad seeing and clouds) prevented us from finishing the test. ---=== OBSERVING LOG ===--- Afternoon: ---------- We had troubles loading the new test version of iop: Error message - INFORMATIONAL: Product 'iop' (with qualifiers ''), has no test chain (or may not exist). Steph was contacted and she told us not to worry. The new version will be tested during the ET run instead. Collimator temperature set at ~12C. Spectro focus was adjusted ~5000 for the blue camera. 02:13Z - Started ventilation with doors and louvers open, fans on. Night: ------ 02:40Z - Opened enclosure. 03:08Z - Cartridge 9, segue139 bright plate 2449 mounted. This plate was already declared done, but needs to be observed again, as requested by Jim Gunn. 03:29Z - GSFOGTF. Precals taken. 03:40Z - Started 20 min exposure. Seeing 3.0-4.0". Not enough signal, so it was declared bad. 04:00Z - Started 20 min exposure. Had a hard time guiding because of clouds and really bad seeing. Still not enough signal, so it was aborted before readout. 04:20Z - Attempted another 20 min exposure, but aborted it again because of bad seeing and clouds. 05:05Z - Because of bad seeing (wind from east) and clouds, we thought that we would not be able to get useful data, so we closed and started imager monthly checkout. 05:35Z - Mounted the imager and started imager biases/flats - runs 6863 and 6864 (about 35 frames each). warning from checkBias: im> checkBias 6863 35 . {61 WARN: } {61 FAIL: leftRNComp } Open /skycat/imager/54275/6863-35-u-bias.gif/gif Open /skycat/imager/54275/6863-35-g-bias.gif/gif Open /skycat/imager/54275/6863-35-r-bias.gif/gif Open /skycat/imager/54275/6863-35-i-bias.gif/gif Open /skycat/imager/54275/6863-35-z-bias.gif/gif Open /skycat/imager/54275/6863-35-o-bias.gif/gif Open /skycat/imager/54275/6863-35-l-bias.gif/gif Open /skycat/imager/54275/6863-35-t-bias.gif/gif Open /skycat/imager/54275/6863-35-s-bias.gif/gif {photo h13} {astro h14} Results of the 'biasCheck' for bias run 6863: Writing file /astrolog/54275/idBiasCheck-006863.par CCD 11 Offset.
