4:10 stop LBC-r exposures

5:19 the sky is more clear now we try to observe Caccianiga program, we slew to J1333
  • 5:22 no guide star found, To checks the pointing, we can barely see the check pointing star, clouds are too thick
  • 5:29 try again the target J133, guide star too faint (R 13.6 mag)
  • 5:34 guide star found, we are acquiring the target, 5:41 lost guide star
  • acq mods1r.20180511.0014-15

9:13 slewing to Caccianiga GB6J182917 _640915
  • target in the part of the sky covered by clouds, guide star not found, we change target

9:19 slewing to Spiniello KIDS1453 (right in the region free from clouds)
  • 9:22 seeing 1.1" on guider
  • 9:25 now we lost the guide star
  • 9:27 the sky is completely covered by clouds
  • 9:35 trying acq again mods1r.20180511.0032-0036

  • 9:57 some clouds coming in, guide star dims by 1 mag, file 37 and 10 are good
  • 10:05 the GCS stops guidiing, we have to send acq again
  • 10:08 acq mods1r.20180511.0038-39, spec mods1r.20180511.0040, mods1b.20180511.0011
  • 10:29 reached airmass limit we stop
  • 10:35 we try to slew to Caccianiga GB6J182917 +640915
  • too many clouds acquisition very hard, guide star lost several time, we give up at 11:04
