NOVA IN M31
R. R. Treffers, A. V. Filippenko, B. Leibundgut, Y. Paik, L.F.M.
Lee, and T. Matheson, University of California at Berkeley; and
M. W. Richmond, Princeton University, report their discovery of a
nova in M31 (R.A. = 0h40m00s, Decl. = +40 59'.7, equinox 1950.0).
The object was found during the Leuschner Observatory Supernova
Search, which uses an automated 0.76-m telescope equipped with the
Lawrence Berkeley Laboratory CCD camera. It was detected in an
image obtained on Aug. 27 UT, at R = 15.9 +/- 0.3, located about
10" east and 101" south of the nucleus (or 8" east and 14" south of
a nearby star). Confirmation was made on Aug. 29 with the 0.50-m
Berkeley Automatic Imaging Telescope, but the nova had already
faded to R = 16.8 +/- 0.3. No object appears at this position to
limits of R = 16.3, 16.2, and 15.9 in images obtained on Aug. 18,
21, and 24, respectively. A noisy spectrum (range 310-1000 nm)
obtained on Sept. 12 with the Shane 3-m reflector at Lick
Observatory reveals unusually broad H-alpha and H-beta emission
lines (FWHM about 4400 km/s) superposed on a weak continuum.

NOVA SAGITTARII 1993
Independent photographic discoveries of an apparent nova have been
reported by Matsuo Sugano, Minami-Oda, Hyogo, Japan (via S.Nakano,
Sumoto), and by William Liller, Vina del Mar, Chile. The object is
located at R.A. = 18h09m.7, Decl. = -29o30' (equinox 1950.0),
situated approximately midway between, and slightly to the north
of, two stars of mag 10. Magnitude estimates: Aug. 27.02 UT,
[11.5 (Liller; Tech Pan film, orange filter); 14.508, 9.0 (Sugano;
Tri-X film); 16.043, 7.9 (Liller).
