afternoon   PESSTO_calib and PESSTO_bias OBs executed
            slit position - specpol      OB  executed

UT 23:00    start of night

UT 23:00    [specpstd  HD 80558]                               gr13
** half-wave plate stuck
** removed half-wave plate manually in dome, lost ~50min until problem identified &
   resolved

UT 23:55    [std       l745a]
** did not find star due to proper motion. aborted.

UT 00.00    acq  OGLE-2013-SN-016 
** rotated by rotator offset angle = 160° (Tried different angles manually in 
   telescope control, starting from parallactic rot. offset angle = 167° and moved 
   guide probe around until finally a guide star was found. due to several error msgs
   etc. etc. this all took 50 min.)
