APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday September 16, 2010 (MJD 55456) ---=== OBSERVING TEAM ===--- Alaina Shelden Kaike Pan ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- The first half of night was lost to rain, high humidity, and clouds. We opened at 05:30Z, and observed 1 marvels plate and two BOSS plates under cloudy sky and okay to poor seeing. One marvels plate: cart 7, plate 4102B. Possible broken fibers: 1/2 and 65/66. Two Boss plate: c12, plate 4226, and c16, plate 4239. Neither done. Problem: We had a warning messages explains about motor C position everytime when pistons were moved. But motor c actually is at its destination. Below is a example of messages. sos 230 boss w text="value for motor positions was bad: ['2341', '-470', 'NaN'] ---=== OBSERVING LOG ===--- Afternoon: ---------- All actors are checked. BOSS bias, darks, calibs were taken. SoS did not reduce acr on b2 with an error: rejected due to big wavelength gap from 3983.8 to 5460.7. aporedo did not get it re-reduced. Took a bias, and another arc, SoS reduced them without any problem. Telescope and systems were checked. No problem to report. 00:20Z MARVELS lamps on. 00:45Z rains, high humidity prevents us from ventilation. Night: -------- 01:30Z we had a serious alart: boss.SP2LN2Fill Reported by camCheck. We checked temeratures on b2 and r2, they are fine. We noticed that the secondary fill was done about 20 min ago. In case, we did boss sp2cam raw=1 stopfillseq boss sp2cam raw=startfillseq. We will keep an eye on it. 04:30Z humidity don to 65%. Started ventilation. But the sky is still overcasting, Plus nearby radar returns. 05:30Z Enclosure off. 05:57Z Marvels calibs T05:59:30.470.fits TIO 44056.555 4841.6401 T06:01:35.810.fits THAR 316.12500 731.75531 T06:06:11.260.fits TIO 43978.668 4842.4282 06:00Z cart 7, plate 4102B.

SOGTF. 07:15Z do a full hartmann since the moon is still up. 07:28Z started science exposures under cloudy sky and poor seeing for first three exposures. Conditions are slightly improved for later expsoures. We obtained 7 15-min expsoure on the plate. But there are almost no signals on first three. The plate is not done yet. 09:30Z cart 16, plate 4239. SOGTF. 09:40Z started science exposures. Sky was partly cloudy. Seeing varied from 1.5 to 2.5". We obtained 5 expsoures before we had to close for high humidity. 11:05Z Humidity was up 86%, dew point difference at 2.4 C. We decided to close. 11:20Z endNight finsihed.
