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
