Details

02:00 start wiht the photometric standard SA98
  • send the preset
  • dohybrid
  • 02:09 run SA98_Vrg_Izr.ob
  • 02:20 during the last images lost the controll of the elevation drive

02:36 slew to De carli's target
  • send preset
  • 02:38 dofpia, /X2
  • 02:44 run copointing.ob
  • 02:48 run the scientific ob
  • seeing 2.2" due to wind gusts (speed >10m/s)
  • 03:11 seeing 2.2", extintion 0.2-0.5 mag
  • 03:25 seeing 1.8"
  • 03:40 seeinf 1.8, extintion 0.3 mag
  • 03:42 dofpia
  • 03:47 run the science ob
  • 03:58 seein 1.6" extintion about 0.3"
  • taken 23/30 images each channel

04:20 slew to Venemans' target P135p16
  • dofpia
  • 04:36 copointing
  • 04:40 run P135p16_zband.ob, seeing 2.0", sky clear (extintion 0 mag)
  • 05:10 seeing 2.5" extintion circa 0.5 mag (bad seeing due to thw wind)
  • 05:27 seeing 2.2"
  • 05:55 seeing 2.1" about 0.5 mag extinction
  • seeing 1.9"
  • 06:15 dofpia
  • 06:20 run P135p16_iband.ob
  • 06:52 seeing 2.3" and extintion increasesd
  • 07:27 seeing 1.4"

07:30 come back to De Carli's program
  • dofpia
  • 07:40 copointing
  • run science ob

07:58 switch to MODS

08:21 send the presete for the standard star Feige 34, collimation

08:37 acqBinoMODS Feige34_Acq.txt
  • mods1r.20190304.0002-0003,mods2r.20190304.0002-0003
  • 08:43 sci mods1r.0004-0006,mods1b.0002-0004, mods2r.20190304.0004-0006, mods2b.0002-0004 dual grating, clouds are coming
  • mods1r.0007-0009,mods2r.0007-0009 red grating

09:09 TO unwraps the telescope.

09:13 Gilli's program, mask 36 the target is in the middle of the clouds, it is impossible find the guide star. 09:18 too many clouds on the sky, we wait

09:22 we send again the acq script, the sky is clearer
  • mods1r.0010-0012, mods2r.0010-0012
  • dimm seeing , fwhm 1.8", extintion 1-2 mag, speed wind is increasing
  • At these coordinates (S-E) there are too many clouds and the targ is in front of the wind, we abort.

09:44 we try the target USS1 of PrandOni program beacuese it is in the North. there are too clouds also here, we can not guide

10:10 TO closes the dome

11:00 TO opens the dome

11:14 send the preset for the target of Moretti, FKJ1344, but it is impossible to guide, the guide staris about 15 mag and we can not change it due to pivot.

11:20 we try with the target of Prandoni, the guide star is about 14 mag.
  • it is impossibile to align, to many clouds

11:54 sky complitely cloudy. WE CLOSE
