     A. Retter and S. O'Toole, University of Sydney; R. Stathakis
and J. Pogson, Anglo-Australian Observatory; and T. Naylor, Exeter
University, report:  "Using the Anglo-Australian Telescope (+ RGO)
on Jan. 26.77 UT, we observed the possible nova reported on IAUC
7808.  Preliminary analysis of the medium-resolution spectra
(400-700 nm) shows that they are dominated by strong emission lines
and possibly weak P-Cyg profiles.  The strongest lines are H-alpha,
H-beta, and Fe II (multiplets 42, 74, 48, 49, 55, etc.).  The FWZI
of the H-alpha and H-beta lines is 2350 +/- 100 km/s.  The object
is, therefore, very likely a classical nova that belongs to the Fe
II class, caught in the early decline phase."
     Prediscovery magnitude estimates:  Jan. 19.854 UT, 8.9 (T.
Seki, Kochi, Japan; photographic; communicated by H. Sato, Sukagawa,
Japan, and T. Kato, Kyoto University); 21.854, 8.5 (H. Nishimura,
Kakegawa, Shizuoka, Japan; T-Max 400 film; communicated by Y.
Muraoka, Hamamatsu, Japan, and Kato); 24.843, 9.0 (Nishimura).
Visual magnitude estimates:  Jan. 27.333, 9.2 (J. Garcia, Rama
Caida, Argentina); 27.658, 8.9 (M. Linnolt, Honolulu, HI); 27.833,
9.0 (A. Pearce, Nedlands, W. Australia).

SUPERNOVA 2002ao IN UGC 9299
     P. Martin and W. D. Li, University of California at Berkeley,
report the LOTOSS (cf. IAUC 7514) discovery of an apparent
supernova on an unfiltered CCD image taken with the 0.8-m Katzman
Automatic Imaging Telescope (KAIT) on Jan. 25.5 UT (mag about 14.3).
SN 2002ao is located at R.A. = 14h29m35s.74, Decl. = -0 00'55".8
(equinox 2000.0), which is about 16" east and 10" north of the
diffuse nucleus of UGC 9299.  The new object was confirmed at mag
14.7 in an image taken with the Beijing Astronomical Observatory
(BAO) 0.6-m telescope on Jan. 26.9 by Y. L. Qiu.  Images of the
same field taken with KAIT on 2001 June 28.3 (limiting mag about
19.0) and with the BAO 0.6-m on 2002 Jan. 4.9 (limiting mag about
17.8) showed nothing at this position.  D. West, Mulvane, KS, also
obtained confirming CCD images of SN 2002ao with a 0.2-m reflector,
yielding position end figures 35s.72, 56".5, and the following
magnitudes:  Jan. 27.492, R_c = 14.83; 27.507, V = 14.96.

     Visual m_1 estimates by A. Pearce, Nedlands, W. Australia
(8x40 binoculars):  Jan. 1.53 UT, 6.0; 12.53, 6.0; 27.85, 4.6
