SA: Olga Kuhn (on call)

Moon phase: 

Summary: Ran LBC with pretty much no hiccups for nearly the entire
         night, almost finished all the OSU_monitor targets. Switched
         to MODS at the very end to try and get ASASSN-18jd, but 
         we missed our narrow window. 

         Finished up with some cals. Tried the UM_M83/M83_F1.cal script
         but there was an IMCS failure to lock followed by a repeated
         error with the blue filter. Olga will have someone look into
         this during the day.

Minor technical issues: See above, blue filter.

Calibrations: LBC twilight flats
              More of the standard MODS cals, and also M83_F1.cal
