COMET P/1995 Q3 (SHOEMAKER-HOLT 2)
     J. V. Scotti, Lunar and Planetary Laboratory, reports his recovery
of comet P/1989 E2 (= 1988 XI = 1989j) with the 0.9-m Spacewatch
telescope at Kitt Peak.  The object is of stellar appearance.  The
indicated correction (ignoring perturbations) to the prediction by
D. W. E. Green on MPC 22032 is Delta T = -1.2 day.
