3:37 executing LBC-r script for r-sloan

4:10 stop LBC-r exposures

5:19 the sky is more clear now we try to observe Caccianiga program, we slew to J1333

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

• 10:29 reached airmass limit we stop
• 10:35 we try to slew to Caccianiga GB6J182917 +640915
