COMET P/1993 W1 = 2005 T1 (MUELLER)
     E. J. Christensen has reported the recovery of comet P/1993 W1
(= 1993s = 1994 XXV) on CCD images taken with the 1.5-m reflector
in the course of the Mt. Lemmon Survey, describing the object as
having a condensed 8" coma and a 20" curved tail in p.a. 250-280
deg.  The recovery was confirmed at the Minor Planet Center via
LONEOS incidental astrometry (0.59-m Schmidt telescope) by M. E.
Van Ness, and earlier observations were subsequently also reported
by F. Fratev (Zvezdno Obshtestvo Observatory, Plana, 0.25-m f/4.7
reflector).  The indicated correction to the prediction on MPC
54168 is Delta_T = -0.8 day.
