PERIODIC COMET SINGER BREWSTER (1992e)
J. V. Scotti, Lunar and Planetary Laboratory, reports his recovery
of this comet with the Spacewatch telescope, Kitt Peak.  The last
image is very slightly diffuse, with an 8" coma visible.  The
indicated correction to the prediction on MPC 14595 (ephemeris MPC
19703) is Delta T = -0.84 day.
