Details

01:23 Wake up MODS

• take test images mods1r.20160108.0101,mods1b.20160108.0081

02:17 begin the saracco program

• acqMODS mods.4.XLSms2.acq mods1r.20160112.0001-0004

02:41 execMODS mods.4.XLSms2_3.obs mods1r.20160112.0005-0008

• seeing very variable 1.1''-1.6''
• 02:55 better seeing, variable between 1.0'' and 1.3''
• 03:08 seeing variable 1.2''-1.5''
• 03:30 mean seeing 1.5''
• 03:38 seeing 1.2''-1.4''

03:54 the seeing is too variable and it is more than 1.2'', so out of spec, we slew to Antoniucci target V1118ori( back up program)

• acqMODS v1118ori_ls.acq mods1r.20160112.0009-0011
• execMODS v1118ori_ls.obs mods1r.20160112.0012-0015 mods1b.20160112.0001-0004
• 04:07 seeing 1.4''-1.6'' mods1r.20160112.0016-001

04:37 target V1647 ori

• acqMODS v1647ori_ls.acq mods1r.20160112.0016-0019
• execMODS v1647ori_ls.obs mods1r.20160112.0020-0023 mods1b.20160112.0005-0008 the blue images are very very faint, wrong posangle , to be repeat
• mean seeing 1.5''
• execMODS v1647ori.img mods1r.20160112.0024-0026, mods1b.0009-0011 the images present the effect of reflection

05:46 come back to V1118ori to run imaging

• execMODS v1118ori.img mods1r.20160112.0027-0029, mods1b.0012-0014, the target is saturated, we take one image with texp=25 sec mods1r.0030, mods1b.0015, the blue is saturated , the red almost good, we take another image with texp=20 sec mods1r.0031, mods1b.0016 are saturated again, try texp=10sec, mods1r.0032, mods1b.0017, the blue has some pixel saturate, the red is ok, we reduce the texp for the blue t=5 sec. now it's ok mods1r.0033, mods1b.0018 we take other two image in the blue and one in the red, as asked by the PI. mods1r.0034, mods1b.0019-0020
• seeing 1.0'' -1.3''

06:14 slew to the stellar standard GD71 (red + dual grating) * acqMODS gd71.acq mods1r.0035-0036 * execMODS gd71.obs mods1r.0037-00, mods1b.0021 * seeing about 0.9-1.0''

06:57 the seeing now is better (1''-1.2'') we pass to LBC

07:15 begin Marconi program

• /dofpia, /x2, /first
• copointing IZw18_copointing.ob
• 07:30 problem with lbcrangebal with device, close and start again ds9 and iraf
• 07:40 copointing again with success
• 07:43 start the science IZw18_1.ob
• seeing 1.0''

08:02 slew to Bellazzini program, target C

• dofpia, /x2
• copointing 2015B_1_C_pointing.ob, problem with the copointing, ds9 do not speck with iraf,close and start again ds9 and iraf
• copointing again
• 08:20 start the science 2015B_1_C.ob
• seeing 1''-1.2''

08:40 the seeing is out of spec to continue Bellazzini program, we slew to Annibali

• dofpia, /x
• copointing
• 08:54 we send the calibration ob given us from the PI
• 08:58 send scientific ob DDO68_1_new.ob
• seeing 0.8''- 1.0''
• the last 4 images have stars a little bit elongated, we run again the dofpia and the copointing, the images are not better, run the dofpia again with double time exposure

09:54 send the second scientific ob DDO68_2_new.ob

• seeing 0.8''
• the first image is good (lbcr.20160112.095436, lbcb.20160112.095441)
• from the the image 2 the sources are elongated, the target is at zenith and the guider has problems. at a high elevation (less than 1) the LBCs are rotating really fast its hard to maintain good guiding the images are elongated in both, we have to change target

10:15 slew to target I of Bellazzini

• dofpia, copointing 2015B_1_I_copoint.ob
• run science 2015B_1_I.ob
• seeing 0.9''
• 10:28 during the acquisition of the first image, the tracker gives error
• seeing 1.0''-1.1''

10:42 slew to J target

• the TO restarts the tracker
• 10:48 dofpia, copointing 2015B_1_J_copoint.ob
• 11:00 run the scientific ob 2015B_1_J.ob
• seeing 0.8''-1.0''

11:15 slew to K target

• technical error
• 11:24 the TO resolves the problem, run dofpia again and copointing 2015B_1_K_pointing.ob
• 11:37 run science 2015B_1_K.ob
• seeing about 1.0''

11:51 slew to L target

• dofpia, copointing 2015B_1_L_pointing.ob
• 12:02 run science 2015B_1_L.ob
• seeing about 0.8''

12:17 slew to M target

• dofpia, this target is very near to L, so it is useless to run the copointing
• 12:22 run science 2015B_1_M_pointing.ob
• seeing 0.8''-0.9'''

12:38 slew to Annibali target

• dofpia and copointing DDO68_copointing.ob
• 12:48 run the scientific ob DDO68_2_new.ob
• seeing 0.6''-0.7''
• the first image is ok in both channel (lbcr. ,lbcb.20160112.124457), the second imaging is smearing, the TO restart LBC.
• the elongation is due to a tracker error, the images were not actually guiding.

13:00 run DDO68_2_new.ob

• seeing 0.8

13:10 stop the science, airmass out of spec. the first three images are good, the other have elongated sources.

13:20 run the photometric standard

13:30 skyflat

14:15 bias LBC
