INAF LBC+LUCIFER queue observing, 2010 October 08-09

Observer: V. Testa, K.Boutsia, M. Fumana
Telescope Operator: D.Gonzales Huerta
Support Astronomer: O.Kuhn
Instrument: LBC - LUCIFER

Summary

good clear sky, start taking LUCIFER flats and then switch to LBC
LBC filter wheel #2 stuck (probably). had to switch instrument.
Seeing on average decent: below 1" in the IR, ~1.1-1.4 in R (according to the AG FWHM)

Details

00:35 - open and prepare for IR flats (J,H,Ks)

00:55 - Ks flats (15000) 0001-0010

01:03 - H (saturates 0011-0021 saturated) flush detector back to Ks

01:05 - Ks (medium level) 0021-0030

01:07 - H (still high ~24000) 0031-0040

01:09 - back to Ks for the low ones 0041-0050

• 4000 cts

01:11 - back to H (~15000) 0051-0060

01:13 - J (~15000) 0061-0070

01:16 - H low (~5000) 0071-0080

01:18 - J low (~4000) 0081-0090

• Meanwhile switch on LBC before inst. switch

01:19 - SWITCH TO LBC

01:38 - Slew to ACT0219 for pointing correction

• OB execution error - left main mirror failed to focus

01:41 Repeat ACT0219 acquisition

• pointautoadjust/mirradjust
• no limits hit this time...

01:47 - Slew to PHOT_STD SA113_BV_VI

• dofpia,/First - this option introduces bigger spherical to enlarge the pupil
• Doesn't converge - Interrupted
• manually put Z7=-2000 (Red+Blue)
• dofpia,/First

02:08 - Exposure STD SA113_BV_VI

• during 4th exposure OB was blocked - lost connection with telescope
• TCS focus error (warning)
• LBC kill/start

02:25 - Repeat Exposure STD SA113_BV_VI

02:30 - Last Blue Image different background in lower and upper part

02:31 - Slew to AndXXI

02:35 - dofpia warning on red filters

• redone first fastextra OB timeout error on red filter wheel #1 (r-SLOAN) hardware failure no chance to restart it.
• turn off/turn on the instrument

02:47 - restarted, wheel #1 always blocked. Seeing not exciting. Go back to Lucifer

02:51 - SWITCH TO LUCIFER

03:25 - Slew to Hip102970 (sn2010gi) acquisition 0091-0093

03:29 - Science HIP102970

• 5sec dit is almost saturated 0094-0095
• redo with 2sec dit 0096-0097
• still seems saturated - we repeat with mode NORMAL 0098-0107 (?)

03:38 - Slew to SN2010gi -acquisition- (Turatto) 108-112

03:52 - Science script for spectra SN2010gi (longslit) 113-128

05:05 - Calibration Unit IN

• FLAT 129-159
• ARC 158-166

05:12 - Lost azimuth drives

05:22 - Cal Unit OUT

05:23 - 2010gi acquisition for imaging 0167-0168

05:29 -Science script for imaging SN2010gi

• H 0169-0172
• J 0173-0176
• Ks 0177-0180

05:41 - Slew to Telluric1 (Longhetti)

• acquisition 0181-0184

05:59 - Science script Telluric 1 0185-0192

06:03 - Slew to Longhetti science target

• acquisition 0193-0196

06:28 - Science script Longhetti 1st run 0197-0204

• at the end of the OB offset Y +64 to go back to starting position

07:12 - Science script Longhetti 2nd run 0205-0212

• at the end of the OB offset Y +64 to go back to starting position

07:57 - Science script Longhetti 3rd run 0213-0220

• at the end of the OB offset Y +64 to go back to starting position

08:43 - Science script Longhetti 4th run 0221-0228

• at the end of the OB offset Y +64 to go back to starting position

09:28 - Science script Longhetti 5th run 0229-0236

• at the end of the OB offset Y +64 to go back to starting position

10:14 - Science script Longhetti 6th run 0236-0243

• at the end of the OB offset Y +64 to go back to starting position

10:50 - End of script, guiding stopped during last image. 8th of 8 probably not good.

10:52 - Move to Telluric 2

• acquisition 244-247

11:02 - Science script Telluric 2 0248-0255

11:07 - Back to Longhetti target

• no star found
