Table 2: 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.
