06:05 We continue the Wolter's program NGC2276 S6/3-c with imaging
  • DIMM seeing 0.73"
  • The 50'' is too big, lost guider, and hit the copointing limit.
  • We create a new OB with acquisition on 50'' offset and take the imaging

06:37 We are continuing the Wolter's program NGC2276 S6/3-c providing the spectra with offset +-5" in x (left and right).

  • = 10 min loss= During the acquisition, we had a problem with the IMCS-Lock of MODS2 and we lost an acquisition slit image. We re-did the procedure and the second time every acquisition images was taken.

  • We did also an imaging without offset before to take the spectra.

08:36 We are observing the target 4FGLJ0955+35 of the Paiano DDT.
  • DIMM seeing 0.95"
  • acq =mods1r.0077-0082 =, =mods2r.0081-86 =
  • DIMM seeing 0.8"
  • Problem with the guide stars: the stars are different for the two telescopes. This happened because there is another star with similar magnitude close the guide star choosen. We lost about 15 minutes to fix it.
  • sci mods1r.0083-89 ,mods1b.0043-49- mods2r.0087-93,mods2b.0044-50
  • Weather is perfect: T=-3C. Humiditu=32%, Wind=8m/s, no clouds!
  • DIMM seeing 0.9" and stable
  • The MODS-1 B spectrum number 0047 has to be rejected because is noise - we re-did the observation to obtain this missing frame.

10:40 We observe the standard star GD153 for the Paiano DDT with slit 5
  • DIMM seeing 0.98"
  • acq =mods1r.0090-91 =, =mods2r.0094-96 =
  • DIMM seeing 1.0"
  • sci mods1r.0092-94 ,mods1b.0050-52- mods2r.0097-99,mods2b.0051-53

11:00 We observe the standard star GD153 for the Paiano DDT with slit 1.2
  • DIMM seeing 0.98"
  • acq skipped because we use the previous one, although it is not optimal
  • DIMM seeing 1.0"
  • sci mods1r.0095-97 ,mods1b.0053-55- mods2r.0100-102,mods2b.0054-56

11:20 At the moment to change the source, some clouds were approaching. We stopped the observations for 10 minutes. No sources were available for the observations due to the faintness of the sources, the sky position contrains and seeing restriction. We decided to re-repoint again 4FGL0955+35 that can be observed also with no-spectrophotometric sky.
  • DIMM seeing 1.00"
  • acq =mods1r.0098-102 =, =mods2r.00103-107 =
  • sci mods1r.0104-105 ,mods1b.0056-0057- mods2r.0108-0109-,mods2b.0057-0058

Notes from the night: We has IMCS lock problems all night and in total we estimate around 10 min of lost time

13:40 Ciao, we close the shop!
