Summary

Night duration (12\xB0 el twilight) 1:15-13:15 UT = 12h 00m

Observing time: h min (88%) 1.5 hor loss because we could not guide with LBC on Annibali R19, According to Olga email 2019/01/10 was a telescope problem.

Weather time loss: 0h m (0%)

technical time loss 1h 30m (12%)

Data Summary

At the sunset the sky is mostly clear, some cirrus on the horizone

Project_RUN Objects Instrument Configuration ExpTime /Time_tot Images Notes
Cusano NW1,2,3 LBC B (blue), V (red) 1.98/3.15   pass some cirrus during the first hour. Done 22...27, but NW3_27 NOT OK: lost guiding
Fabrizio photcal LBC Ug (blue),ri (red) 0.08/0.08 h   completed
Fabrizio TriII _bright LBC Ug (blue),ri (red) 0.06*2/0.06*2 h   completed
Fabrizio TriII LBC U (blue),r (red) 0.42*2/0.42*2 h   completed
DeCarli SDSSJ0842+1218 LBC z (red) 0.7/2h   also got 0.7h in blure r band. Check last 17 images on red, from 08:45 maybe too bad,
Annibali R19 LBC g (blue), r (red)     maybe, the guiding star is not good, maybe , please try again
Annibali R20 LBC g (blue), r (red) 1h/1h   completed

  • 04:42 NW-3_27.ob
  • do again copointing and NW-3_27 because guide star lost
  • 04:57 NW-3_27 again
  • seeing 1.0" on dimm
  • 05:05 lost connection and got again
  • NW-3_27 not good guiding problem!

05:08 slew to photometric standard for Fabrizio's program
  • dofpia
  • 05:17 start photcal OB
  • not good the OB has probelms onlu U and r filters

05:40 lost connection

05:45 slew to TriII bright
  • dofpia
  • copointing

05:50 TriII bright, U,r
  • seeing about 0.75"

  • seeing 1.1" on image at 06:40 UT

06:56 slew to phot_cal to do g and i bands
  • dofpia
  • 07:01 start OB

07:05 slew to De Carli
  • dofpia
  • copointing
  • 07:16 start science
  • exposure 5-6 on red stars elongated. Seeing is too good
  • dimm seeing 0.5-0.6"
  • 07:50 connection lost again
  • seeing 0.6" on dimm
  • 08:10 dofpia
  • 08:24 send script again
  • seeing 0.6" on dimm
  • seeing 0.8" on image at 08:47
  • 09:14 stars are elongated on red, we do again the dofpia
  • we notice that the last half hour last 17 images on red, from 08:45, are too bad, not collimated, probably not good
  • 09:20 copointing
  • 09:25 run the ob again but the stars are elongated yet, we ask to the OT to clear the active optics.

09:31 slew to Annibali's program, target R19
  • dohybrid
  • copointing at 09:46
  • lost connection at 09:50
  • send OB 1 at 09:52
  • guiding problem maybe
  • dofpia again at 10:00 UT, in the blue channel it doesn't find pupils. We stop the procedure with control S, but is stuck
  • 10:12 dofpia, /backout. dofpia again but it is not good
  • we try the dofpia with a new copointing file.
  • 10:26 start science OB 1
  • 10:27 connection lost
  • seeing 0.7" on image at 10:28
  • 10:42 we stop again, there are problems with the guide stars, in the blue channel the stars are elongated.
  • dofpia, /X2 but it doesn't work
  • we run the dofpia in the copointing field. dofpia, /X2
  • 10:53 run again the science script
  • 10:58 the stars are elongated.

11:03 to undertand if the problem is due to the field or LBC we change target, slew to R20
  • 11:05 dofpia, /X2
  • 11:10 copointing
  • 11:15 run UGC5666_1.ob
  • the guide stars are elongated in the LBC panel
  • the first is good, the second one has stars a little bit elongated close to the borders, but OK
  • seeing about 0.7"on dimm
  • 11:42 dofpia
  • 11:46 run UGC5666_2.ob
  • seeing about 0.8"on image at 12:05
  • the second-last (penultima) images of red and last 2 of blue are elongated
  • dofpia at 12:14
  • 12:18 run UGC5666_3.ob
  • dimm seeing 0.7"
  • 12:25 seeing 0.8" on image
  • 12:35 seeing 0.8" on image
  • dofpia
  • 12:53 take calibration field
  • 12:56 take again 2 images of OB2 to revover bad guiding images

13:10 Slew to phot standard for Annibali and De Carli SA 101 gr_rz
  • dofpia
  • 13:19 SA101_gr_rz

SKY FLATS
  • primo set r+z t conteggi troppo bassi
  • r + z PA=0 tutte buone, 180 prese prime 2 buone
  • g+i PA=180 ok maybeonly 2 i are ok
  • B+r PA=180 e 2 PA=0
  • U+V PA=180 saturated

BIAS 25 bino bias
