Malcolm Hartley took a 110 minute exposure on 1994 July 6.6 with the 1.2-m UK Schmidt Telescope at Siding Spring and found a 16m comet, which was also present on a plate taken the night before. The comet was approaching opposition and nearly stationary on the border of Grus and Microscopium. It proved to be a relatively distant short period comet with a period of 21 years and a perihelion distance of 2.5 au.  Aphelion is beyond the orbit of Saturn and there have been no recent approaches to it or Jupiter. 1994 N2 (P/McNaught-Hartley) was recovered by PanSTARRS in images taken with the 1.8m Ritchey-Chretien on 2014 June 29, though it took further images taken at the MASTER-SAAO Observatory, Sutherland with the 0.4m reflector on 2015 March 31.1 to confirm the recovery.
