APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday June 1, 2008 (MJD 54619) ---=== OBSERVING TEAM ===--- Shannon Watters (observer) Dmitry Bizyaev (observer) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Mostly clear sky in the evening, but we noticed a lot of pine pollen in the air and closed telescopes. We started imager calibrations and completed Linearity or u 1,2,3, and 4. We are leaving LN2 spectro dewar really low after fill at ~ 4:15 MST. Please check it! Please check the mirror for the pollen. ---=== OBSERVING LOG ===--- Partly clear sky in the evening with numerous scattered contrails. We were concerned about pine pollin and opened later when pollen could be seen in the light of flashlights. 02:20Z Dome opened; started ventilation Cart. 3 plate 2927 is on (seguefaint) GSOGTF After sunset we noticed growing pollen particles population in the air. Cleaned windshield got noticeable layer of pollen. There are polen particles in the air. We managed to close the telescope and dome. It's a pity, seeing looks perfect, sky is mostly clear. 03:09Z dome closed. We set up imager for calibrations. --- run 7536 03:55Z bias fr.1 03:57Z u 1 Linearity fr. 2 -- 03:54Z MSP bias - Frame 1 --------------------- 02:37Z Linearity on u 1 w/ stageX = 2310 First Frame - idR-7536-u1-2.fit Last Frame - idR-7536-u1-21.fit ---------------- 05:56Z Linearity on u 2 w/ stageX = 11410 First Frame - idR-7536-u2-22.fit Last Frame - idR-7536-u2-40.fit --------------- 07:17Z Linearity on u 3 w/ stageX = 20510 First Frame - idR-7536-u3-41.fit Warning! too low flux on photodiode! aflux 0. < 5000*(exptime) 7536 56 u3 im cameraNag {} t-g-sdss-2.apo.nmsu.edu 3500 2008-06-02 08:12:23Z: opening camera doors MSP: Unsolicited response "flux -1652.4 aflux 167703.6 volts 0.0001 avolts -0.0094 voltsRms 0.0010 avoltsRms 0.1989 ping lambda 380.0 time 5.929 stageX 205100 lambda 380.0 time 5.929 WARNING!
