Details
01:30 start Flat Fields
02:05 photometric standard SA95
- dofpia
- 02:10 send the ob
- seeing 0.85''
2:23 slew to Marconi's program.
- send copointing IZw18_copointing.ob
- dofpia
- 02:30 in the middle of the dofpia the machine obs2 is stucked, we pass to obs3
- the AS controls that everything is ok and continue the dofpia
- 02:40 lbcrangebal
- 02:46 run science IZw18_6.ob
- seeing 0.7''
- 02:53 some cirrus start forming
03:00 we slew to Raimondo's program
- run UMaII _f3_UBr_point.ob
- dofpia, lbrangebal
- 03:23 UMaII _f3_UBr.ob
- 03:32 seeing 0.7'' on LBC-red
- 03:40 seeing 0.62'' on LBC-red
- 03:56 seeing 0.7''-0.8'' on LBC-red
04:03 run dofpia on
UMaII _f4_UBr.ob
- 04:09 run UMaII _f4_UBr.ob
- 04:20 seeing 0.73'' on LBC-red
04:59 run dofpia on
UMaII _f5_UBr.ob
- 05:05 run UMaII _f5_UBr.ob
- 05:23 seeing 0.65'' on LBC-red
- 05:34 seeing 0.63'' on LBC-red
- 05:40 some clouds start forming
05:55 we slew to Castellano A program MACS J0717.5
- run copointing wt10_318_point.ob
- dofpia, lbrangebal
- 06:05 run Castellano_MACSJ0717_UV_7.ob
- 06:22 seeing 0.75'''
- 06:39 seeing 0.76''
- 06:47 dofpia
- 06:51 run Castellano_MACSJ0717_UV_8.ob
- 07:00 dofpia again, the stars in the red channel are a little bit elongate (eccentricity is about 0.8-0.11) (the last dofpia failed in the red channel)
- 07:06 run Castellano_MACSJ0717_UV_8.ob
- 07:11 seeing 1.0''
- 07:17 the clouds are increaseing
- 07:22 the counts of the backgroud are increaseing due to the combination of the effects of moon and clouds , the images in the red are not good but in the blue are also good, we wait the acquisition of the last image in the blue and we stop
- 07:30 stop
07:30 slew to LUCI, deBarros' program
- 07:55 the TO send the preset
- there are a loto of clouds, the sky is pretty bad.
8:09 load the Telluric script and slewing to the field. GO
M103GLASS2c _tell
- 8:15 abort collimation due to impossibility to collimate in the cloudy sky ( clouds moving fast from west )
- the sky is covered, problem with acquisition and resolved (luci2.20162229.0194-0197), lost guiding star...but we have a spectrum of the telluric star
luci2.20162229.0198
, and after few seconds the scripts stopped...
- 08:39 the sky is clearer, the telescope is guided, we continue the script
luci2.0199-0201
- seeing is about 0.8''
- 08:43 offset failed, images from 0202 to 0205 are not good
- 08:48 go again the script for the telluric but the sky is covered again and the telescope can not guide. We can not observe
09:09 the sky is a little bit clearer, we try again the acquisition of the telluric
- the TO searches a pointing star
- load the script for the telluric
- 09:15 acquisition of the telluric star
luci2.0206-0208
but there are problems with the focus
- the AS trys to initialize the detector focus but the problems still remain
9:38 we decide to take the scientific data by hand
luci2.0209-0214
we forget the dithering
- we follow the dithering of the PI
luci2.0215-0217
are ok
-
luci2.0218-0217
are not good, there are not the spectrum
9:50 stop the technical problem with automatic acquisition
- with the AS we control the offset given by the PI
luci2.0222-0226
- we understand that the initial slit for the acquisition is wrong
10:20 acquisition telluric again
luci2.0227-0229
- 10:30 science in automatic mode
luci2.0300-0307
10:41 slew to scientific target GO
M103GLASS2c.xml
- acquisition
luci2.0238-0.241
- 11:23 spectra
luci2.0242-0244
but we do not see the spectra (to 0244)
- load again the script and take the acquisition
luci2.0245-0248
- 11:40 again clouds but the seeing is very good 0.5''
luci2.0249-0254
- run again the science
GO M103GLASS2c.xml =luci2.0255-0260=
seeing 0.5''-0.6''
- 12:14 GO M103GLASS2c.xml
luci2.0261-0262
the last one take during the twilight
12:59 begins the twilight, stop the observation
13:04 close the dome
13:28 begin flat for the program deBarros
- flat without lamp
luci2.0263-0267
with texp=30 sec
- 13:32 flat with the lamp HALO3
luci2.0268
texp=30 sec, counts are low (about 1000)
- take again the flats with HALO 3 and texp=60 sec
luci2.0269-0273
13:41 LBC bias
13:45 flat without lamp and texp=60sec
luci2.0274-0278
- arc-neon
luci2.0279-0283
texp=60sec
- arc-argon
=luci2.0284-0288
texp=5sec
- flat without lamp and texp=5 sec ==luci2.0289-0293
