SUPERNOVA 2001dj IN NGC 180
     M. Papenkova and W. D. Li, University of California, report
the discovery by LOTOSS (cf. IAUC 7514) of an apparent supernova in
unfiltered images taken with the Katzman Automatic Imaging
Telescope (KAIT) on July 29.5 (mag about 17.9) and 30.5 UT (mag
about 17.7).  The new object is located at R.A. = 0h37m52s.22, Decl.
= +8o38'33".0 (equinox 2000.0), which is 80".8 west and 27".1 north
of the nucleus of NGC 180.  A KAIT image taken on Jan. 5.2 showed
nothing at this position (limiting mag about 19.0).


NOVA IN M31
     Li also report the discovery of an apparent nova in M31 (= NGC
224) on unfiltered KAIT images taken on July 28.5 (mag about 18.0)
and 30.5 UT (mag about 17.5).  The nova is located at R.A. =
0h42m30s.72, Decl. = +41o14'36".8 (equinox 2000.0), which is 153"
west and 92" south of the nucleus of M31.  A KAIT image of the same
field taken on July 26.5 showed nothing at this position (limiting
mag about 19.0).


V1494 AQUILAE
     R. J. Rudy, S. Mazuk, C. Venturini, and D. K. Lynch, The
Aerospace Corporation; R. C. Puetter, Center for Astrophysics and
Space Science, University of California at San Diego; and P.
Mortfield, Stanford University, report on 0.8-2.5-micron
spectrophotometry of V1494 Aql, using the Lick Observatory 3-m
telescope (+ Aerospace Near Infrared Imaging Spectrograph) on July
10.6 UT, about 580 days after peak brightness:  "The nova is in a
strengthening coronal phase (see IAUC 7490) with lines of [Al IX],
[Ca VIII], [S VIII], [S IX], [Si VI], [Si VII], [S IX], [Si X], and
possibly [S XI] present.  The latter, at 1.9196 microns, requires
photon energies > 447 eV to produce.  Many of the lines have
double-peaked profiles and have typical line widths (full width at
half maximum) of 2900 km/s.  The continuum decreased monotonically
with increasing wavelength and showed no evidence of thermal
emission from dust."


COMETS C/2000 S3, 150P, C/2000 Y2, C/2001 G1, C/2001 HT_50
     The IAU Committee on Small Bodies Nomenclature has agreed upon
the names for the following five comets:  C/2000 S3 (LONEOS);
150P/2000 WT_168 (LONEOS); C/2000 Y2 (Skiff); C/2001 G1 (LONEOS);
C/2001 HT_50 (LINEAR-NEAT).
