APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday November 12, 2007 (MJD 54417) ---=== OBSERVING TEAM ===--- Dan Oravetz (swing) Kaike Pan (observer) Viktor Malanushenko (observer) ---=== OBSERVING PLAN ===--- SN & SEGUE Science! ---=== OBSERVING SUMMARY ===--- Because it was overcast at the time of twilight ended, we decided to start the night with some cloudy night tasks. We did Spectro darks and biases. After 4:00Z we decide mounted Imager. We can observed only part of SN stripe: 82,S, lam. from 173 up to -123. The seening was less than 1.4". Because the clouds come again, we start Spectro observations. We finished plate 2700 (cart.8) with some extra signal. Some problems was at the start Imager's observations with FocusLoop. (see in to 'log' section.) ---=== OBSERVING LOG ===--- Afternoon: ---------- All systems checked and working properly. As of 22:32Z there are 408G available on /data and 400G available on /files. Spectro focus set for ~6C. Night: ------ Because it was overcast at the time of twilight ended, we decided to start the night with some cloudy night tasks. 01:32Z Spectro biases: frame 47304 -- 47328 Filename 02% 05% 10% 50% 90% 95% 98% ------------------- ------ ------ ------ ------ ------ ------ ------ sdR-b1-00047316.fit -6.2 -4.1 -3.0 2.2 7.5 8.5 10.2 sdR-b2-00047316.fit -8.1 -6.3 -4.4 1.3 6.7 8.8 10.3 sdR-r1-00047316.fit -6.9 -5.7 -3.9 1.1 6.3 8.1 9.6 sdR-r2-00047316.fit -8.1 -6.1 -4.9 1.3 6.5 7.7 9.7 ------------------- Dark frames 47329-37331 start at 03:00Z Filename 02% 05% 10% 50% 90% 95% 98% ------------------- ------ ------ ------ ------ ------ ------ ------ sdR-b1-00047330.fit -3.1 -0.9 0.5 6.8 12.3 14.2 16.3 sdR-b2-00047330.fit -4.9 -2.5 -1.2 5.1 12.3 13.9 16.4 sdR-r1-00047330.fit -5.1 -3.0 -1.1 4.6 10.0 12.2 14.4 sdR-r2-00047330.fit -5.7 -3.7 -1.6 3.8 10.1 12.2 15.2 ------------------- 04:00Z clouds started to break out, we decided to mount imager and prepare for on-telescope bias. 04:10Z Imager mounted. 04:22Z Run 7157 - biases on telescope. 05:10Z opened enclosure 05:13Z SN stripe 82,S, lambda=170, run 7158 05:25Z fr.25, lam=173 05:30Z fr.31, lam=174, in focus skippy was happy at the beginnig, nuErr=8.3". nuErr less than 8.0" from fr.220. We had problems with FocusLoop: the secondary mirror did not adjust itself according to CCD60 and CCD90. It was in focus at frame # 31, but gradually went up and got out of the focus at frame # 42, and could not get back in focus (and the trend did not looked like it will get back into the focus). Kaike stopped the focusLoop at frame # 63, and adjust it to the focus position by using tcc setfocus. Then start focusLoop again. the same as before, it we out of focus at frame #70, and could not adjust itself back. At this point, kaike decided to try from another iop session: Stopped the the focus loop at frame # 80 from its running iop session, tcc set focus adjusted it to the focus, and restarted focus loop from a different iop session at frame # 84. This time, focusLoop does what it supposes to do: adjusts the secondary according to CCD60 and CCD90. From frame 31 to 80, fwhm measurements indicated that the seeing was below 1.4", the secondary departed from its focus range by a small amount (less than 10 units), these frames should be good. 08:50Z - clouds come to us... 09:33Z - end science, fr.439, lam=-125. 09:41Z - end ramp, fr.453, lam= -123. 09:55Z Spectro mounted 09:59Z - gotoField, used FK5.
