PERIODIC COMET BUS (1993b)
     J. V. Scotti, Lunar and Planetary Laboratory, reports his
recovery of this comet with the Spacewatch 0.9-m telescope at Kitt
Peak:

The Jan. 1 images are stellar, but the Jan. 21 images showed the
slightest hint of being nonstellar.  The indicated correction to
the prediction on MPC 19257 is Delta T = +0.05 day.
