APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday April 8, 2010 (MJD 55295) ---=== OBSERVING TEAM ===--- Viktor Malanshenko Kaike Pan ---=== OBSERVING PLAN ===--- BOSS Science ---=== OBSERVING SUMMARY ===--- The sky was partly cloudy to mostly cloudy till last two hours. The seeing was not good (1.5" to 3" during the first two hours), then became excellent (~1.2 by the guider, 0.8" by the DIMM). Observed following boss plates: cart 10, plate 3826: Eight 15-min exposures. cart 12, plate 3841: Five 15-min exposures. -- DONE cart 13, plate 3981: Eight 15-min exposures. -- DONE cart 16, plate 3851: Six 15-min exposures -- as a going-deep field. ---=== OBSERVING LOG ===--- Afternoon: ---------- Afternoon check out went smoothly. No problem to report. Cartridge 10, the cartridge for the beginning of tonight was mounted and collimation were checked. The b2 camera was adjusted to its best focus by applying an empirical relations between movement of sp2 pistons and b2 focus ring: moving pistons by -270 steps is roughly corresponding to moving the focus ring by 1 degree. FYI, the sp1, 1 degree ~ -310 steps. 00:05Z started evening ventilation. Night: ------ 01:35Z enclosure off. 02:00Z cart 10, plate 3826. SOGTF. Seeing varied between 1.0" to 2.5" (DIMM), 1.2" to 2.7" (guider). A pair of pre- and post-calibs and Eight 15-min exposures were obtained on this plate. Good seeing (1.2") but thin cloudy sky during last three exposures. The plate is not done yet.
