APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday January 3, 2006 (MJD 53739) ---=== OBSERVING TEAM ===--- Swing: Dan Long Night: Steph Snedden Howard Brewington ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Clouds for most of the night. Completed the nonlinearity exposures for the spectrographs. Declared two plates done (2067 & 2365). ---=== OBSERVING LOG ===--- Afternoon: ------------- Rebooted guider mac to clear too few replies problem. TCC no longer complains about port LTA11. Spectrograph focus checked but not changed. Still set for 3 to 4 C. Details in problem section. Cartridge 2 mounted on telescope. 23:10Z Doors Open, Louvers Open, Fans On Night: ------------- Clouds at twilight, so we did the nonlinearity exposures for the spectrographs. Since exposure times in goStare must be integer values, we had to modify David's suggested exposure time sequences. Lamps were allowed to warm up for 15 minutes prior to each sequence. Frame flavor exp time ----- ------ -------- 36209 bias 0 Probably should have added a 3-sec exposure here, but didn't. 36210 flat 2 36211 flat 4 36212 flat 2 36213 flat 8 36214 flat 2 36215 flat 15 36216 flat 2 36217 flat 30 36218 flat 2 36219 flat 40 36220 flat 2 36221 flat 60 36222 flat 2 36223 flat 80 36224 flat 2 36225 bias 0 36226 arc 2 36227 arc 3 36228 arc 2 36229 arc 4 36230 arc 2 36231 arc 6 36232 arc 2 36233 arc 8 36234 arc 2 36235 arc 12 36236 arc 2 36237 arc 16 36238 arc 2 Here's the 3 second flat that might be useful.

Now, we have more clouds moving in from the west. This plate was declared done when last night's S/N^2 was added to tonight's.

We completed one exposure in clouds, but the S/N^2 was not >2. Brian Yanny declared plate 2067 done.

When the telescope has been at stow for an extended period (say all day), sp2 gets quite a bit colder (as much as 2 or 3 C) presumably due to the boil off of the camera dewars above the spectrograph body in this orientation. Note: When collimate is run in version v5_1_0 there is a warning message "speclog_version: Command not found." It doesn't appear to effect the calculations but is not seen in v4_10_7.
