INAF LBC+MODS+LUCI queue observing, 2012 October 24-25

Observer: M. Faccini, E. Sani, K. Boutsia
Telescope Operator: G. Bechetti
Support Astronomer: M. Edwars
Instrument: LUCI, LBC


At the beginning of the twilight we have clear sky with wind gusts at 15-18m/s
At the beginning of the night the seeing is 1.7 and the wind is lowering
During the spectroscopic acquisition of SN2009ip we have problems with collimation. The target is too low (<30elev) and the seeing is high. We observe nevertheless because the PI asked the data under any conditions.
Before starting the second filter (HKspec), we take a through-slit image and the target seems to still be in the slit. We go on even though collimation gets worse. Guiding also fails and we have tracking
At the end of this project, the collimation is so bad that we have to call D.Miller. Trying to re-collimate LUCI, the Cresci target goes out of specs and we switch to LBC.
LBC was more stable tonight. Even though we rolled back to build-2012F, the elongation problem was not completely solved and we had to switch off guiding again at some point.
During twilight we tried to obtain 2 standards, but at the second one the background is too high. Also twilight flats are somewhat hight but they should be usable.

00:52 We start with flats calibrations for the J, H, Ks filters
  • flatKs.txt luci.0005-0034
  • DoFlats_sunset.txt luci.0035-0119

01:49 We slew to La Franca A15
  • OB_LaFranca_A15_acq.txt luci.0120-0126

01:54 OB_LaFranca_A15_spe.txt luci.0127-0128
  • this is a test to verify whether the reference/telluric star saturate. The star does not saturate.
  • Perhaps the centering of the slit is not perfect and require to be refined through a small field rotation.
  • A standard star is already within the slit.

02:15 We slew to Turatto 7B
  • we start with the imaging to verify the offsets.
  • SN2009ip_oct2012_H.img luci.0129-0140
  • We abort the imaging because we can not see the target on the acquisition image. This is problably due to a bad seeing of 2.5

2:25 We slew to the spectroscopic program Turatto 7A
  • SN2009ip_ls.acq luci.0141-0144

02:36 SN2009ip_zJ.spec luci.0145-0156
  • The collimation is not good

3:43 We try to check the guiding luci.0157-0162
  • Even if ther is no collimation, we verify that the target is still in the slit.

3:49 SN2009ip_HK.spec luci.0163-0171
  • We loose the guide star and have to restart the script. This happens twice.

04:45 We perform the imaing in the Ks-band.
  • SN2009ip_oct20012_Ks.img
  • We are at 25.3deg in Elevation, there is no way to guide. NO Ks imaging
  • The J- and H- bands imaging was performed during the acquisitions of the target.

04:51 We slew to the Telluric Hip117452.

05:05 We can not point any target. We have Dug online

05:44 Manual collimation.

06:52 We abort Cresci A program because we are no able to collimate.
  • We ask the TO to slew to a bright star near Giallongo 27A and collimate to measure the seeing with the DIM.
  • Nonetheless we have problems with the LBC software.
