INAF LBC+LUCIFER queue observing, 2010 December 02 - 03

Observer: K.Boutsia, M. Fumana,V. Testa
Telescope Operator: S. Allanson
Support Astronomer: D. Thompson
Instrument: LBC - LUCIFER

Summary

Thin clouds and airplane trails in the sky during twilight - no Sky Flats taken
Seeing <0.8''
RPC error with the trackers, we had to turn OFF - turn ON LBC
Smooth night, overall some thin clouds, great seeing

Details

Begin night with LBC

12:10 Connect LBC to LBT

• 25Bias_Bino

12:41 - Slew to pointing star WT10_351

• Pointing correction OK + mirror adjust OK

12:53 - slew to Clementini - AndXXI -dofpia

• manually give corrections but it converges rather fast

01:24 - observing target Clementini - M31_AndXXI_420s_11

• Seeing good - <0.8'' from the dimm
• sky might be still a bit high during the first offset
• seeing <0.8 in the Blue and <0.6 in the Red
• blue images slightly elongated...

01:50 - slew to AndXIX - dofpia

• Blue Rotator has stopped at 41 during slewing for dofpia ... eventually it goes to correct position but it takes some extra time

01:56 - observing target Clementini - M31_AndXIX_420s_11

02:19 - slew to AndXXI - dofpia

• stopped after 4th iteration - some residual defocusing on the blue side

02:28 - observing target Clementini - M31_AndXXI_420s_12

02:52 - slew to AndXIX - dofpia

• dofpia,/X2 because we are at very high elevation

03:01 - observing target Clementini - M31_AndXIX_420s_12

• blue looks better this time

03:26 - Slew to AndXXI - dofpia

• dofpia,/X2 - it seems to give better results

03:36 - observing target Clementini - M31_AndXXI_420s_13

04:01 - Slew to AndXIX - dofpia

• dofpia,/X2

04:11 - observing target Clementini - M31_AndXIX_420s_13

• Blue guide star seemed out focus during first exposure but image looks fine (0.7'')
• Red image has a slightly worse seeing than blue (0.95'')
• second exposure both guide stars look fine
• during last exposure guide star on the red side looked out of focus. Red side seeing worse than on Blue side

04:36 -Slew to AndXXI - dofpia

• dofpia,/X2

04:47 - observing target Clementini - M31_AndXXI_420s_14

05:14 -Slew to AndXIX - dofpia

• dofpia

05:17 - observing target Clementini - M31_AndXIX_420s_14

• a bit of residual astig on the SX

05:40 - problems with the RED tracker during the last exposure

• RPC host client communication fail
• Turn LBC OFF- ON
• last red image not saved!!!
• SPC not found - reboot please

05:52 - Slew to AndXXI - dofpia

• stopped after 3rd interaction - some defocus left on the blue side

05:58 - observing target Clementini - M31_AndXXI_420_15

06:23 - slew to AndXIX - dofpia

06:27 - observing target Clementini - M31_AndXIX_420s_15

06:52 - SWITCH TO LUCIFER

07:26 - Pointing correction

07:29 - Slew to Pentericci cluster 1

• acquisition 0001-0006
