INAF queue observing, 2013 April 6 - April 7

Observer: E. Sani, M. Faccini, A. Bongiorno
Telescope Operator: D. Gonzales Huerta
Support Astronomer: D. Thompson
Instrument: LBC

Summary

At sunset we have thin clouds on the horizon, low wind and humidity at 37%.
During the first part of the night we have good seeing ~0.7 and thin cirrus, mostly on the horizon.
After 06.20 UT the sky is mostly clear, with thin cirrus remaining only at the SE horizon.
In the second part of the night we have completely clear sky and good seeing <1.0.

Details

01:26 Run 25Bias_Bino.ob

01:55 The TO opens the Dome

02:03 Start with flats calibrations

02:06 Run SkyFlatTest_SF_r0651d+42_pa0_5.ob with time scale =1 (blue=24000; red=6000)

• we need the red. too low

02:08 Run SkyFlat_SF_r0651d+42_pa0_5.ob with time scale =3 (blue=40000, red=9000) red too low

02:10 Run SkyFlat_SF_r0651d+42_pa0_5.ob with time scale =7 (blue=45000, red=9000) red too low

02:15 Run SkyFlat_SF_r0651d+42_pa180_5.ob with time scale =10 (blue=9000, red=2100) both too low

02:48 Run CLJ1120+43_POINTING.ob

• Too early, the sky is still bright

02:58 dofpia, /first, /X2 on pointing field Giallongo

• red channel converged with only a pupil
• We got a command rejected because another command was running. the SA reset the LBC.

03:07 dofpia, /first, /X2 on pointing field Giallongo

• extra spherical correction is too much.

03:12 dofpia, /X2 on pointing field Giallongo

• dofpia is not working correctly, the inner hole is still too large and the evaluated seeing is 2.7, totally unconsistent with <1.0 in the DIMM
• the TO clears all the primary mirror settings.

03:15 dofpia, /first, /X2 on pointing field Giallongo

• bad fitting from dofpia, perhaps the field is too crowded. We go 0.2deg West to collimate.

03: 21 dofpia, /first, /X2 0.2 West from pointing field Giallongo

03:27 Run CLJ1120+43_POINTING.ob

• lbcrangebal B=032738 R=032734

03:30 Run CLJ1120+43_c.ob

• at the beginning of the integration the average seeing is 0.6 in R-channel and in 1.0 in B-channel (perhaps some defocus remained in B from the previous dofpia, e.g.: 033520).
• due to aberrations in the B channel, we stop the integration and re-run dofpia

03:42 dofpia, /X2 on scientific field Giallongo

03:46 Run CLJ1120+43_c.ob

• the average seeing is 0.7 in R and in 1.1 B. Some elongation does persist in B-channel (e.g. 034732).

07:47 Run grazian_GOODSN_UR_31.ob

• at the beginning of the integration the seeing is 0.8 in R-channel and 0.9 in B-channel
• at the end of the integration the seeing is 0.8/0.9 in R-channel and 0.9 in B-channel
• "jump" in blue frame 080419

08:29 /dofpia, /X2 on scientific field Grazian

08:34 Run grazian_GOODSN_UR_32.ob

• at the beginning of the integration the seeing is 0.65 in R-channel and 0.9 in B-channel
• at the end of the integration the seeing is 0.8 in R-channel and 1.2 in B-channel

09:15 /dofpia, /X2 on scientific field Grazian

09:20 Run grazian_GOODSN_UR_33.ob

• at the beginning of the integration the seeing is 0.8 in the red channel and 0.9 in the blue one
• at the end of the integration the seeing is 0.9 in the red channel and 1.0 in the blue one

10:03 Slew to standard SA104 filters US, B, g - V, r, I

10:07 dofpia ,/X2 on standard field

• at the end of the integration the seeing is ~1 in the red channel and ~1 in the blue one

11:27 Run Umi_2.ob

• at the beginning of the integration the seeing is 0.7 in the red channel and 0.9 in the blue one

12:14 We start the flat fielding in Uspec-I

12:33 Run SkyFlat_SF_pa180 scale factor = 3.0 (2 sets: 1st good in S, 2nd goon in F)
