COMET P/2006 U2 (JEDICKE)
     J. V. Scotti, University of Arizona, reports the recovery
of comet P/1995 A1 with the Spacewatch II telescope at Kitt Peak.
The object looks essentially stellar -- no obvious coma or tail
-- though the image appears just a little 'softer' than stars of
similar brightness in the field.  The indicated correction to the
prediction on MPC 51823 is Delta(T) = -1.0 day.
