296P/Garradd = 2007 H3 = 2014 A1Gordon 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.Date10x10 magErrorKphot magComa '19 Jun 1418.560.3018.40.22 Jul 1418.750.0718.60.25 Aug 1418.620.0918.50.227-Mar-2019.54 0.24 18.70.2
