COMET P/2008 G2 (SHOEMAKER)
     While examining Apr. 10 single-night observations of minor planets
reported by the Catalina Sky Survey to the Minor Planet Center, T. B. Spahr
identified a candidate (first observation given below) for comet P/1994 J3
= 1994k = 1994 XXVIII (Shoemaker, a.k.a. Shoemaker 4; cf. IAUC 5991, 5998,
etc.).  The undersigned then identified a corresponding candidate in the
Catalina data from Apr. 1.  In each case the observer was R. A. Kowalski,
and nothing was reported about the object's appearance.  The indicated
correction to the prediction on MPC 56803 (ephemeris on MPC 60734) is
-1.7 days.

an ephemeris appear on MPEC 2008-H20.
