- At 23:55 UT 1st integration of HIP008102 delayed because it was too low East. - At 00:40 UT Dome DISABLED + LIMITS on a reachable targetHIP008102 (dome stops moving: Why? ): third instance in 5 nights. --- --- solved: Dome Functions -> Dome Track + Slew Z + c to verify ZP. - At 00:51 UT Dome DISAB+LIMITS again (moving to G2K002554) - 2 UT cloudy to almost overcast. Object #25 (HD9270) repeated, cloudy, bad guiding. Files 1140 and 1141.fits 02:55 UT overcast + Moon: waiting. Trying at 4UT still cloudy. Weather improved around 07:30 UT, clear except due North. Manually guiding most of night, when it was possible. DIMM down most of this cloudy night. In the program many objects appear as SEND but were not observed because of the weather conditions. Last object completed with Sun at -10.1 degrees. Did not complete the program.
