SUPERNOVA 2002aq IN MCG -01-7-35
     P. Martin and W. D. Li, University of California at Berkeley,
report the LOTOSS (cf. IAUC 7514) discovery of an apparent
supernova (mag about 18.7) on unfiltered CCD images taken with the
0.8-m Katzman Automatic Imaging Telescope (KAIT) on Feb. 1.2 and
2.2 UT.  SN 2002aq is located at R.A. = 2h41m57s.44, Decl. =
-6 47'46".4 (equinox 2000.0), which is 7".3 east and 14".2 south of
the nucleus of MCG -01-7-35.  A KAIT image taken on Jan. 20.2
already showed a hint of the new object, while an image taken on
Jan. 11.2 showed nothing at this position (limiting mag about 19.5).


COMET C/2002 C1 (IKEYA-ZHANG)
     Precise astrometry (Feb. 1-2) and the preliminary parabolic
orbital elements given below appear on MPEC 2002-C03.  Visual m_1
and coma-diameter estimates:  Feb. 1.910 UT, 7.5:, 5' (P. M.
Raymundo, Salvador, Brazil, 0.25-m reflector; independent
discovery); 2.081, 9.5:, 3' (A. Hale, Cloudcroft, NM, 0.41-m
reflector; thin clouds); 2.43, 8.8, about 4' (K. Yoshimoto,
Yamaguchi, Japan, 20x100 binoculars); 2.47, 8.8, 3' (D. Zhang,
Kaifeng, Henan, China, 0.20-m f/4.4 reflector, 28x, as used for the
discovery on Feb. 1.47; comet more condensed than on previous day);
2.53, 9.1, 3' (A. Pearce, Nedlands, W. Australia, 0.2-m reflector);
2.53, 8.5, 5' (N. Brown, Quinns Rocks, W. Australia, 0.15-m
refractor).
