Observer: V. Testa, K.Boutsia
Telescope Operator: D.Gonzales Huerta
Support Astronomer: O. Kuhn

Summary

Candidate photometric - seeing <1.0
Problems with the telemetry of the Blue channel. Last part of the night we switched to Red Only mode.

Details

02:21 - Opening the dome - starting interface

02:30 - test Flats to monitor sky brightness 0001-0060

02:35 - Sky Flat fields

in the K band - imaging

• 2secs / 11000-9000counts 0001-0010
• 2secs / 7000-6000counts 0011-0020
• 2secs / 4500-4000counts 0021-0030

in the H band

• 2secs / 9000-7000counts 0031-0040
• 2secs / 6000-4000counts 0041-0050
• 2secs / <3000counts 0051-0060

T/O corrected pointing from his position. Double check with pointing star

03:00 - Pointing Star near the field (WT10_385) 0061-0062

• ptcorr, vey small correcton, procedure worked fine

03:06 - Persson standard BS9145 for collimation (POSITION,ACTIVE)

03:16 - Collimation - preset to Mannucci HDFN acquisition script for MOS

• Lost guiding star, trying alternate one. No way. Check pointing again.

03:25 - Pointing ok, maybe sky still too bright.

03:31 - Change guide star, ok. Collimating

03:37 - MOS acquistion on HDFN K 0063-0067

03:45 - only 4 stars for reference 2,3,4,7 skipped

• do a through-slit again to check
• +0.12 in X to better center the ref. star into the slit

03:58 - HDFN H mos science script 3

• 300DIT x 1NDIT x 12 exp 0068-0079

Give Y+1.5 offset to go back to original pointing

05:07 - through slit (0080-0086 discard) 0087

05:13 - HDFN H mos science script 4

• 300 DIT x 1NDIT x 12 exp 0088-0099

06:20 - Calibration unit in: arcs and flats

• ARCS Ar OFF 0100
• ARCS Ar ON 0101
• ARCS Xe OFF 0102
• ARCS Xe ON 0103
• FLAT Halo1 OFF 8sec 0104-0106
• FLAT Halo1 ON 8sec 0107-0109
• We have doubled the exposure time for the flat aquisition

06:36 - Telluric 0111-0150

• not integrated but normal, every DIT saved separately
• exposure time 3DITx10NDIT

06:41 - SWITCH TO LBC

07:01 - Switch complete

• Go checking the poiting WT10_298
• ptautoadjust ptmodify IE -22.153254121718 ptmodify CA -66.44293373613

07:19 - Q1623_Uspec_2

• in Uspec does not do IA online, probably no objects in the tech chip

(telemetry error in the blue temperature, gave temperature limit exceeded 17.4 instead of -50 celsius)

08:02 - Q1623_Uspec_3 *08:09 - again temperature liits exceeded spoiled 5 min exposure).... 08:21 - again!!!!!! f!@@#@#$@ telemetry!!!!! CCD controller error, OB exited in error *08:26 - Power OFF/ Power ON then move to 6791 red only

08:35 - Slew to NGC 6791 try binocular first

08:50 - Red Only, dofpia (strangely, it did not took the fastextra OB, but ran the WD6791 that had been stopped while pointing....)

10:17 - WD_N671_LONG_02 Only red * Sky brightens at the end, twilight ongoing * last two skipped for saturation

11:20 - SkyFlatTes_redV

• twice , second one has ~1000 cts/s

11:26 - SkyFlat_redVi_5 V=5s, i=10s

• after the 8th, reduced to 3,6

11:32 - Again but changing dither pattern and V=1s, i=2s

11:38 - Again but changing dither pattern and V=1s, i=1s

Meanwhile sent DoDarks for Lucifer

11:45 - End of Night
