APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday June 5, 2003 (MJD 52796) ---=== OBSERVING TEAM ===--- swing Daniel Long night Jurek Krzesinski and Howard Brewington ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We opened twice tonight and in both cases didn't get enough S/N. Night lost do to clouds and humidity. Otherwice there were no problems. For a few TPM watcher errors see the problem section. ---=== OBSERVING LOG ===--- Afternoon: ---------- The 2.5m checkout went smoothly. No problems. This afternoon the spectrographs were refocused. Below are the mean offset values from collimate.

Fk5, used to find guiding stars. When we finished with precalib, clouds moved over and we couldn't see any star (even fk5). Then we were trying to get some photons in a hole between clouds. After 10 minutes of exposure we endstared - clouds covered the whole sky. We read out the exposure, but S/N was below 2. 07:15Z Enclosure moved on the telescope. 07:51Z Humidity rised to 80% and is growing, we closed doors and switched off the fans. 10:05Z Cart 4 plt 1023 mounted, stars on slew. We already are in twilight. Well - we'll see. No, the seeing is terrible, efficiency meter below 25%. We gived up. 10:26Z Closing. Starting endNihgt on cloudy tapes, and it went ok. A few TPM errors enclosed in the problem section. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 3981 22:02Z 22:23Z 100 O -66.32 -61.09 48 ignore ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot az el --------------------------------------------------------------------------- ---=== LTMATCH RESULTS ===--- Run Field nFields alt az nGood rowMean rowSig colMean colSig rot ------------------------------------------------------------------------ ---=== SPECTROSCOPY DATA SUMMARY ===--- Summary Checked (y/n): yes QA Procedures Done (y/n): yes: bias, flat, arc ok. target got to low S/N.
