Instrument: LUCI - MODS   

Summary: During the day LUCI had a communication issue between filter
wheel and camera mechanism. Solved during the evening by restarting the
software (Michelle). At sunset, dome closed due to clouds. Dome opened
at 01:13. We observed through thick cirrus and clouds from UT1:40 to UT
04:55, when we closed the dome due to clouds. We used the closed time to
get LUCI and MODS calibrations. We called the night at UT 11:30.

Weather: At sunset, dome closed due to clouds. At opening, thick cirrus
ahead, thick clouds at the horizon. Bright moon during the 1st part of
the night. UT 02:45 humidity~60%, cirrus, bright moon. UT 03:14, weather
conditions getting worse (cirrus+clouds). UT 03:35 Sky almost entirely
covered. UT 04:55 close dome due to clouds: overcast.

UT 01:13 Opening dome

UT 1:27 good to slew to target, collimation shows 1” seeing,
   thick cirrus and patchy clouds

UT 1:40 -- OSU_UCDz -- SL234449B -- HK_Science
   filter wheel failure during first attempt to run script
   Script repeated twice in order to get enough S/N (thick cirrus,
   seeing very good)

UT 2:15 -- OSU_UCDz -- SL234449B -- Jz_Science
   Change grating
   Script repeated twice in order to get enough S/N (thick cirrus,
   seeing very good)

UT 2:45 -- OSU_UCDz -- SL234449B -- TelluricJz
   Starting to have guiding problems, due to cirrus+moon
   Took telluric spectra without guiding
UT 2:58 -- OSU_UCDz -- SL234449B -- TelluricHK (clouds+cirrus)
   filter wheel issue
   needed to re-acquire telluric star before a last set of exposures
   since we were not guiding
UT 3:28 -- OSU_UCDz -- SL234449A_HK (clouds+cirrus)
   guide star very bright, we made it out of the cloud
UT 3:36, starting integration
   Script repeated twice in order to get enough S/N (thick cirrus, seeing
   very good)
UT 4:04 -- SL234449A_zJ (clouds thickening - humidity rising to 60%)
   Script repeated to get sufficient S/N
   barely guiding, sky almost entirely covered
UT 04:40 last exposure of series had no trace. Sky covered equally in
   clouds - running exposures in case the we hit a hole and get some
   target flux, but officially not getting data due to weather
UT 04:55 close dome due to clouds

LUCI calibrations:

UT 5:14 -- OSU_BALQSO_He/HIP50459 dark for a modified exposure time

UT 5:16 -- AZ_Lensspec dark.cal

UT 6:40 -- UVa_BCD_flat
   checked the last 2 flats - short on counts compared to others.
   re-running without explicit lamp time set (seems to be incorrect)

UT 6:52 -- ND_sn11fe
   wrote flat script for PI (flat_zJ.cal) because none was provided.

UT 7:05 -- OSU_Lensmass_J_flat.cal
UT 7:29 -- OSU_Lensmass_HK_flat.luci
UT 7:28 -- ND_sn11fe
   wrote flat script for PI (flat_HK.cal) because none was provided.

UT 7:49 -- ND_sn11fe
   wrote arc script for PI (arc_HK.cal) because none was provided.

UT 7:53 -- OSU_Lensmass_HK_arc.luci
UT 8:15 -- OSU_Lensmass_J_arc.luci
UT 8:32 -- UVa_BCD_arc.obs
UT 8:40 -- ND_sn11fe
   wrote arc script for PI (arc_zJ.cal) because none was provided.

UT 8:49 -- done with cals for now

UT 10:10 MODS calibrations
   slit flats, new exposure times in order to get maximum ADU ~ 20000-30000
   blue grating: slitflats_b_new.cal (images mods1b.20121121.0008,
   mods1b.20121121.0009 wrong exp time)
   blue grating, bin 2x2: slitflats_b_new_2.cal

UT 11:30 still overcast, we called the night.
