APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday December 21, 2008 (MJD 54822) ---=== OBSERVING TEAM ===--- Elena Malanushenko Dmitry Bizyaev Kaike Pan (Swing) Viktor Malanushenko (PT) ---=== OBSERVING PLAN ===--- SEGUE spectroscopy/BOSS imaging science night. ---=== OBSERVING SUMMARY ===--- Winter solstice. The longest night in the year is over. Spectro: Useful signal added to plates 3105 (c.2), 3185 (c. 5), and 3155 (c. 1). Finished plate 3167 (cart. 9). Photo: Stripe 84 N observed with imager from lambda -170 to -138 (including ramps). Stripe 69 N observed with imager from lambda -177 to -153 (including ramps). (The second low priority stripe was taken because the top priority stripes were no longer available at technically possible altitude 25 deg. at the moment of observations). Laptop's mouse on the telescope is hard to operate because of dirty trackball (probably). Needs to be cleaned. ---=== OBSERVING LOG ===--- Afternoon: ---------- All systems were checked. Spectro focus was checked but no adjustment was made. It is set for about 1.5 C. 23:23Z started ventilation, fan on, louvers open, doors open. ntp_check ok imager bias ok spectro bias ok Filename 02% 05% 10% 50% 90% 95% 98% ------------------- ------ ------ ------ ------ ------ ------ ------ sdR-b1-00057460.fit -5.3 -4.2 -2.9 2.4 6.8 8.7 10.1 sdR-b2-00057460.fit -8.7 -6.2 -5.0 1.2 7.3 8.9 11.0 sdR-r1-00057460.fit -6.9 -5.5 -3.7 1.5 6.5 8.3 10.5 sdR-r2-00057460.fit -8.5 -6.4 -4.5 0.8 6.2 8.3 10.2 Night: ------ 00:10Z dome opened. 00:46Z gotoField with cart. 2 plate 3105. fk5 used 00:57Z precal sp1, sp2> mechPiston 2000 01:11Z one more 01:20Z science 1800 01:54Z science 1200 --> 1800 postcal -- 02:44Z cart. 5 plate 3185 mounted connection to tcc gets either slow or broken. tccClose / startDa -tcc performed. fk5 used. 02:54Z precal 03:03Z science 1800 --- clouds gone, seeing returned back to under 2".
