SUPERNOVA 2002kf
     S. Brady, Hudson, NH, reports the discovery of an apparent
supernova (mag about 15.9) on an unfiltered CCD image taken with a
0.25-m automated telescope on Dec. 27.1 UT.  The new object is
located at R.A. = 6h37m15s.31, Decl. = +49o51'10".2 (equinox
2000.0), which is about 13".6 west and 10".6 north of the nucleus
of the apparent host galaxy.  SN 2002kf was confirmed on an
unfiltered CCD frame taken by M. Schwartz with the Tenagra II
0.81-m telescope Dec. 28.4, but it does not appear on second
Palomar Sky Survey red or blue plates.


COMET C/2002 V1 (NEAT)
     Ephemeris from orbital elements on MPEC 2002-Y60 (the
magnitudes below assume H_15 = 6.5, though any prediction of the
comet's brightness close to perihelion is necessarily highly
uncertain):
