The comet C2013R1 (Lovejoy) was discovered on September 9th 2013 by the Australian hobby astronomer Terry Lovejoy. At the time of discovery the 14 mag comet was in the constellation of Monoceros near to the border with Orion. Here the comet is photographed on the night of November 25th between 04:00 and 06:00 LT ( 01:00 – 03:00 UT). 2 x 2min LRGB exposures guided on the comet's nuclei (using the comet tracking capability of the ASA DDM 85 mount). At the right bottom is the tiny spiral galaxy NGC 5023. Other information can be found in the object's details table below.
