COMET P/2006 U3 (NEAT)
     R. Stoss, Astronomisches Rechen-Institut, Heidelberg, and
Observatorio Astronomico de Mallorca, reports the recovery by J. L.
Ortiz and A. Mora of P/2001 K1 (NEAT) on CCD images obtained with
the 2.5-m Isaac Newton Telescope at La Palma, the object appearing
asteroidal on 300-s R-band frames.  The astrometric observations
provided below were measured by Stoss.  The indicated correction to
the prediction on MPC 54169 is Delta(T) = -0.4 day.  The recovery
positions appear to confirm the proposed identification of this
comet with an object found by Stoss on Palomar Sky Survey plates
from 1955; the 1955 astrometry falls within 15" of the position
predicted from an orbit linking the 2001 and 2006 observations.
