APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday May 14, 2009 (MJD 54966) ---=== OBSERVING TEAM ===--- Alaina Shelden Viktor Malanushenko Support: on site Stephanie Snedden by phone Craig Loomis ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We observed the following: Segue-2: Cart 2, plate 3404 Marvels: Cart 7, plate 3414A, Field1348 Cart 7, plate 3414B, Field1068 plate 3489 A and B 75,76 on 'A' still broken (already knew that) -- Pointing model problems: Craig issued ticket #228 about "read_fiducials command fails to read file" -- Fiducials table problems: We found that the fiducial table for Az need re-obtained. -- Weather conditions: The dust level was ~ 3000, and humidity less than 25%. We accumulate ~ 22 Kdust. So could you please check both mirrors and clean them if necessary. 09:22Z - the weather server crushed. ---=== OBSERVING LOG ===--- Afternoon: ---------- 00:53Z Afternoon checkout went smoothly--not problems apo_plotbias, 61134 Filename 02% 05% 10% 50% 90% 95% 98% ------------------- ------ ------ ------ ------ ------ ------ ------ sdR-b1-00061134.fit -5.9 -4.6 -2.6 1.8 7.3 9.0 10.6 sdR-b2-00061134.fit -7.8 -6.4 -5.1 1.2 6.9 8.8 10.6 sdR-r1-00061134.fit -6.9 -5.2 -3.9 1.3 6.7 8.9 10.1 sdR-r2-00061134.fit -7.7 -6.0 -4.6 1.3 6.6 8.0 10.1 ------------------- ------ ------ ------ ------ ------ ------ ------ Collimate checked and good for +13 C.

Trying pointing model; MCP ver.6.60; new fiducials table, v.1.80. We got many problems with that. The problems was done together Stephanie and Craig. 06:00Z - 07:00Z -- finding FK5 star, offset and focus. the good offset was: az = -0.02 ; alt = 0.03 good foc = + 145 (Air temperature +13 C) 07:28Z - clouds come to us... 07:00Z - 08:00Z -- we got too large correction for azimuth. The standart correction procedures did not help us.
