INAF queue observing, 2013 February 15-16

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

Summary

At the beginning of night operations there are cirrus scattered over the South sky, with wind gusts at 12 m/s and low humidity.
At the end of the twilight there remain cirrus above the SW orizon, but the rest of the sky is almost clear. The wind is increasing with gusts at 20 m/s.
After 3h from the beginning of the observation the sky is clear.
During the night the average seeing experience huge variations, ranging between 0.8 and 2.
With LUCI we have defocusing during the MOS acquisition. Its origin is currently unknown, but, considering that the effect is small and appears only in the upper part of the mask combined with the bad seeing, it should not affect seriously the scientific frames.
Good sky flats for the LBc Bin are taken during night 20130217.

• the average seeing is 1.8 in the blue channel and 1.5 in the red one.

• Aborted to acquire the B-R images

04.08 Run Linx_BR1.ob

• The average seeing in the blue blue channel is 1.5-1.5 and 1.3 -1.8 in the red channel.

05.18 We slew to the standard star

• Run SA101_BRUV.ob
• dofpia, /X2

05.25 We ask the TO to SWITCH TO LUCI

05.48 We are authorized to use LUCI

05.49 We slew to the standard star for the Zamorani_A1 program

05.56 executeLuciScript.sh M009zCgr32_tell.acq luci.20130216.0002-0003

• There are two bright stars close to each over in the acquisition image and we have no finding chart for Hip 33836. We identify the lower star as the bluer using optical images in simbad.

06.10 executeLuciScript.sh M009zCgr32_tell.spec luci.20130216.0004-0016

06.15 executeLuciScript.sh M009zCgr32.acq luci.20130216.0017-0021

• The first through slit image is out of focus. The SA re-initialize the instrument, but it did not worked. Anyhow with bad seeing conditions (1.4-1.6 on the GCS) the defocusing should not decrease the image quality

06.38 executeLuciScript M009zCgr32.spec luci.20130216.0022-0042

• dimm seeing ~1.2
• dimm seeing is growing over 1.5 (see the first attached plot)

07.50 The seeing start to stabilize around 1.0 (see the second attached plot)

09.00 The seeing is again dancing, and after 3h of integration it increases till 2.0.

10.21 We interrupt the scientific script because the target reached the airmass limit.

10.22 We ask the TO to SWITCH BACK TO LBC
