APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday April 1, 2008 (MJD 54558) ---=== OBSERVING TEAM ===--- Observers: Howard Brewington Audrey Simmons ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We had clouds, so we did imager cals all night. ---=== OBSERVING LOG ===--- Afternoon: ---------- Spectro focus was checked and slightly adjusted. See pre-adjusted collimate numbers in the Problems Section. The space at /data/* was good; see below.

However, the thin clouds over the site were getting much thicker. 01:23Z Sunset 02:00Z Cart 05, plate 2960 (boaTest 187); an fk5 star was used to find the field in bright twilight and thin clouds. Seeing was about 0.8" as reported by the DIMM. Dust = 2.5K We lost the guide stars about twelve minutes into the twenty-minute exposure as a result of increased cloud cover. The exposure was declared BAD. 02:19 51535 10.0 flat 02:22 51536 2.0 arc 02:45 51537 688.0 target 02:47Z Twilight ended 03:00Z Enclosure on, doors/louvers closed, fans off because of very thick clouds and high dust. 04:00Z Clouds were not improving, so we decided to setup for imager cals. R-2, linearity, Run # 7408, frames 01 to 20 I-2, linearity, Run # 7408, frames 21 to 39 06:45Z Clouds were slightly less of a problem; however, only segFaint plates were availale at this time. So, we decided to do another chip. G-2, linearity, Run # 7408, frames 40 to 58 08:00Z We still had clouds, so we continued with imager cals.
