Details

Take some LUCIFER Dark frames in the afternoon for tests
  • 2s (Dark_001)
  • 300s (Dark_002)
  • 60s (Dark_003)
  • 60s (Dark_004) - during switch just for test

Begin night with LBC

01:13 - Skyflat Test LBC - B(blue) - V(red)
  • 3sec B- 1 sec V saturated
  • 0.3x(3 e 1)sec B - V
  • 1.5 sec B - 0.5 sec V
  • PA 180 - 3sec B + 3sec V

01:32 - Slew to pointing star ACT0219
  • Pointing correction OK + mirror adjust OK

01:39 - slew to PHOT_STD - SA113 dofpia,
  • manually give Z7 = -2000(Red+Blue) and Z8=-1000(Red)
  • dofpia,/First
  • sky is still bright - too few pupils found
  • manually give Z4=+10000 (Red ) - Z4=+5000(Blue)

01:53 - Hit limits in red mirror - OB interrupted
  • coma free pointing adjustment on dx

01:57 - restart OB for STD - SA113_B_V

02:01 - Slew to second standard - SA110 _B_V * seeing ~1.3" * temperature fell abruptly 1.5deg

02:06 - Slew to target AndXXI (Clementini)
  • dofpia
  • seeing still bad (1.3"-1.5")
  • Blue converged after 4 iterations, red after 7 stopped with only Z4 slightly out of limits

02:20 - AndXXI OB1
  • sources are slightly elongated - seeing 1.6"(blue)-1.5"(red)
  • guiding problems?? - out of focus?? - just bad seeing??

02:45 - Slew to AndXIX - dofpia
  • stopped after 6 iterations - close to converge

02:55 - AndXIX OB1
  • images still elongated
  • guiding star (especially blue) is moving around a lot!
  • it is a guiding problem (blue is the master)

03:20 - OB finished but we have to solve the guiding problem

03:23 - Slew to AndXXI repeat OB1
  • put Red master and Blue slave
  • dofpia
  • stopped after 4th iteration - some astigmatism left

03:30 - AndXXI OB1 - repeat exposure
  • Red is master

03:47 - OB interrupted - the seeing is bad >1.5" (dimm 2.5")

03:48 - SWITCH TO LUCIFER
  • Pointing Correction by TO

04:16 - Slew to Campo A (Cresci)
  • Ks imaging 0001-0073
  • interrupted after 73 offsets, because it is complete

06:11 - Slew to Campo B (Cresci)
  • Ks imaging 0074-0148
  • Only 75 offsets executed
  • interrupted because airmass limit reached (airmass>1.5)
  • some elongation in the frames at low elevation

08:04 - Slew to PHOT_STD FS152
  • pointing correction
  • imaging in Ks 0149-153

08:26 - Slew to Pentericci Clustrer1
  • MOS acquisition 0153-0156

08:44 - Science spectroscopy script Cluster1 (Pentericci) 0157-0158
  • interrupted because it seemed out of focus
  • INITIALIZE
  • offset 0.0,1.5 (x,y) to bring the mask to initial position

08:59 - Repeat Science SpecScript for Clusted1 159-169
  • Sky lines are shifted and seem out of focus - INITIALIZE made no difference
  • Call Germany - they say they will run tests at the end of night
  • not clear if it moves between offsets or also during exposure (maybe that'a why it seems out of focus)
  • maybe something wrong with the flexure compensation
  • Script interrupted after 10 offsets + the 2 from before -> 12 offsets executed
  • OB is considered finished but it maybe compromised

09:53 - Calib Unit IN
  • ARC with Ar+Ne lamps 168-172
  • ARC with Ar+Xe lamps 0173-0176
  • FLAT 177-180

10:08 - Slew to SN2009kr image acquisition (Turatto) 0181-0182
  • Interrupted to put Flexure compensation OFF
For the rest of the night all imaging scripts have Flexure compensation OFF

10:19 - Repeat SN2009kr image acquisition (Turatto) 0183-0184

10:21 - Science imaging scripts for SN2009kr
  • Imaging H 0185-0200
  • Imaging J 0201-0208
  • Imaging script Ks 0209-0224

11:29 - Slew to SN2010sl for image acquisition 0225-0226
  • Science imaging script H 0227-0234
  • Science imaging script J 0235-0250
  • Science imaging script Ks 0251-0258
  • Sometimes it would give warnings about not reaching the guide star for the particular offset position

12:40 - Move to Flat position
  • used script to make the flats and they were saved as luci_20101011_Flat_)
  • Flats in J: 001-010 still dark, 011-020 low (4000), 031-040 high ( 18000-25000)
  • Flats in H: 021-030 low (6000-9000), 041-050 high ( 18000-23000)
  • Flats in Ks: 051-070 low (5000-8000), 071-090 high ( 14000-17000)

13:22 - END OF NIGHT
  • Hand over the telescopes to Germany for the tests to see what causes the shifting
  • They will run our Darks sciprt
