The comet was discovered by Henry E. Holt and C. Michelle Olmstead (Palomar
Observatory, California, USA) on photographic plates exposed on 14 and 17
September 1990, with the 0.46-m Schmidt telescope. They determined the
magnitude as 17.2. The comet was then located in Pisces. The comet was followed
until 14 December.
Brian Marsden integrated the orbit of the comet forward and predicted the next return
to perihelion would occur on 6 February 1997, which was not a favorable apparition.
James V. Scotti (Kitt Peak, Arizona, USA) recovered it on 19 and 20 September
1996. He said the comet was essentially stellar with a slight hint of diffuseness. The
six available CCD images indicated a magnitude ranging from 20.1 to 20.6.
