INAF queue observing, 2013 February 16-17

Observer: E. Sani, M. Fumana
Telescope Operator: S. Allanson
Support Astronomer: D. Thompson
Instrument: LBC Bin

Summary

The sky is CLEAR at the beginning of the night, with very low humidity and low wind.
At the beginning of scientific integration the seeing on the DIMM is around 1.0.
The sky remains clear all night long.
During the night the seeing is around 1.0 or better.
LBC Bin sky flats taken during this night are good.

00:40 The TO opens the dome

01:26 Run SkyFlat_SF_r0556d+04_pa0_5.ob. Scale factor=0.4

01:30 Run SkyFlat_SF_r0556d+04_pa180_5.ob. Scale factor=2.0

01.36 Run SkyFlat_BR_r1502d+29_pa180_5.ob. Scale factor =1.0

01.40 Run SkyFlat_BR_r1502d+29_pa0_5.ob. Scale factor =2.5

01.46 Run SkyFlat_UV_r1502d+29_pa0_5.ob. Scale factor =10.0

02:11 We slew to the target GJ3470 for Nascimbeni DDT and start the settings

• dofpia,/first,/X2 on target field Nascimbeni
• The guiding is unchecked in the OB execution panel.

02.20 Run

• Without defocusing the refence star does saturate in both channels

02:42 While performing the range balancing we have an error from the blue channel camera that is not integrating. The SA switch off the Panel control and then turns in on again. This does no work and the SA reboots by hand the LBC software. This properly worked

02.53 Defocusing at -0.2 on both channels

• counts on a 60 sec exposure are 34100 in the blue channel and >65000 in the red one
• defocusing at -0.3 in the red channel, both the reference star and the target are above 35000 counts.
• defocusing at -0.1 in the red channel.
• a global defocus of -0.2 in the blue channel and -0.6 in the red should be fine to avoid saturation.

03:06 Run 01_BIAS

• The TO unset the offset to re-run dofpia after the bias acquisition.

03:15 dofpia, /X2 on target field Nascimbeni

03.21 Defocusing at -0.2 in the blue channel and -0.6.

• Run DEFOCUS.ob, a single 60s exposure to check the counts. Counts in the blue channel are around 38000. Counts in the red channel are ok.
• The TO applies an additional defocus of -0.1 in the blu channel.

03.26 Run DEFOCUS.ob

• The counts in both channels are fine.

03.30 Run 02_OBJECT

• the frame lbcb.20130217.3500 has counts >35000.
• We stop the ob, the TO applies a -0.1 defocusing in the blue channel.

03:54 Run 02_OBJECT

• tha frames lbcr.20130217.035747-035747 have 36000 conts.
• The TO applies an additional defocus of -0.1 in the red channel.
• This happens because the seeing is decreasing.

07.09 Run 09_BIAS

07:16 Slew to the standard star fir the Saracco program

• The TO removes the global defocusing (-0.4 for the blue channel, -0.7 for the red channel).
• We select Guiding on the OB control panel *dofpia,/X2

07.23 Run SA101_BRUV.ob

07.31 dofpia, /X2 on the target field Saracco

07.44 lbcrangebal B=074434 R=074432

07.52 dofpia, /X2 on the target field Saracco

07:55 Run Lynx_UV_1

• Clear sky with average seeing 0.7 in the red channel and 0.9 in the blue one.
• Frames lbcb.20130217.075535 and lbcb.20130217.085641 show scattered light due to internal reflection in the bottom left side of chip 1.

09.05 Slew to the standard star SA104

• dofpia,/X2 on the standard field

09.09 Run SA104_Sr.ob

09.12 Slew to Grazian 30A

• Run grazian_pointing.ob
• dofpia,/X2 on the scientific field
• lbcrangebal B=092541 R=092529

09.29 dofpia,/X2 on the scientific field

09.35 Run grazian_GOODSN_UR_07.ob

• Clear sky with average seeing 1.0 and 1.2 for the red and blue channel respectively

10.15 dofpia,/X2 on the scientific field

10.19 Run grazian_GOODSN_UR_08.ob

10.59 dofpia,/X2 on the scientific field

11.05 Run grazian_GOODSN_UR_09.ob

11.50 We upload a wrong ob and moving the telescope far from the scientific field

11.55 dofpia,/X2 on the scientific field

• lbcrangebal B=120308 R=120307

12.08 Run grazian_GOODSN_UR_10.ob * The average seeing is 0.7 and 0.9 for the red and blue channel respectively

12.50 We start the sky flats

• Run SkyFlat_Sr_r1502d+29_pa0_5.ob with scaling factor =10
• low counts

13.10 Run SkyFlat_Sr_r1502d+29_pa0_5.ob with scaling factor =15

• low counts

13.23 Run SkyFlat_Sr_r1502d+29_pa0_5.ob with scaling factor =6

13.26 Run SkyFlat_Sr_r1502d+29_pa180_5.ob with scaling factor =2.5
