127P on Gary W. Kronk’s cometography

Discovery: [ IAUC 5093 ]


This comet was discovered by Henry E. Holt and C. Michelle Olmstead (Palomar Observatory, California, USA) on photographic plates exposed on 1990 September 14 and 17, with the 0.46-m Schmidt telescope. They determined the magnitude as 17.2. The comet was then located in Pisces. The comet was also found on plates obtained on September 16 using the same telescope and the magnitude was determined as 17.0


Recovery Comet P/1996 S1 (Holt-Olmstead): [ IAUC 6475 ]


J. V. Scotti, University of Arizona, reports his recovery of comet P/1990 R2 (= 1990k = 1990 XVIII) with the Spacewatch telescope at Kitt Peak.  The comet appears essentially stellar with a slight hint of diffuseness, and is close to the prediction on MPC 23482 (ephemeris on MPC 26588)
