296P/Garradd = 2007 H3 = 2014 A1 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. Date 10x10 mag Error Kphot mag Coma ' 19 Jun 14 18.56 0.30 18.4 0.2 2 Jul 14 18.75 0.07 18.6 0.2 5 Aug 14 18.62 0.09 18.5 0.2
