Night: ------ 01:29Z Sunset 01:32Z Enclosure off, topped-off spectro secondary dewars, checked top/bottom balance, did a test slew, checked fiducial crossings for each axis, started the DIMM. 01:58Z Cart 07, plate 2859 (segue169). An fk5 star was used to find the field in bright twilight. Seeing was about 1.0" as reported by the DIMM. Dust = 1.5K Seeing deteriorated; guider's estimation was about 2.5" We completed two exposures; both were caget tpm_TM_PMSSAvg tpm_TM_TelairAvg.VALA tpm_TM_PMSSAvg 1.76857 tpm_TM_TelairAvg.VALA 2.2975 sp1> mechSend s spMechVersion v2_9_0 Bootup 870616738 SpectroID 1 SlitID 38 Air On Shutter_open_sensor Off Shutter_closed_sensor On Left_open_sensor Off Left_closed_sensor On Right_open_sensor Off Right_closed_sensor On Coll_motor_A -3050 01P-0000003050 Coll_motor_B -2883 02P-0000002883 Coll_motor_C -1947 01P-0000001947 Coll_motor_A_status 132 01S0132 Coll_motor_B_status 133 02S0133 Coll_motor_C_status 133 01S0133 Requested_exp.time 0 Exp_time_left 0 Last_exp.time 3 Last_open_transit.time 740 Last_close_transit.time 670 Humid_Hartmann -24.6 0x0 Humid_Cen_Optics 9.4 0xFE3C Temp_Median 2.6 Temp_Hartmann_Top 3.6 (0xFF68) Temp_Red_Cam_Bot 3.2 (0xFF78) Temp_Red_Cam_Top 2.6 (0xFF94) Temp_Blue_Cam_Bot 2.6 (0xFF94) Temp_Blue_Cam_Top 2.9 (0xFF88) AD 23359 1094 IDL 5.5a> collimate, 51810 % Compiled module: COLLIMATE.
