Gordon Garradd discovered a 17th magnitude comet on images taken for the Siding
Spring Survey with the 0.5-m Uppsala Schmidt on 22 April 2007. It was confirmed by
N. Teamo and Sebastian Hoenig using a 0.41-m f/8 reflector at Punaauia, Tahiti.
Prediscovery images from March were found in Siding Spring observations. The
comet reached perihelion at 1.8 AU in mid August, and has a period of 6.5 years.
The comet was recovered by an observing team at the Pierre Auger Observatory,
Malargue using the 0.3m f/10 reflector on 6 January 2014. Following recovery
prediscovery NEAT images from 2001 June were identified. The comet was close to
the predicted time of return.
