\caption{Log of the DI broad- and narrowband observations at the ESO
  observatories in Chile.
  For ESO Chile the observing window of the comet started around
  23:30~UT (Sun about 18~deg below horizon) and lasted until 04:20~UT (comet at 20~deg elevation). 
  The following notations are used for the sky conditions: CLR~=~clear sky; THN~=~thin cirrus clouds; COUT~=~clouded out. The seeing values are measured by
  a dedicated seeing-monitoring telescope on-site.\label{log_schedule} }
