     H. Kosai, Tokyo Astronomical Observatory, telexes that Minoru
Honda, Kurashiki, has discovered a probable nova as follows:

     1982 UT          R. A. (1950) Decl.      mv
     Jan. 27.85451   19 20.7     + 2 24       6-7

The observation was made on Tri-X film.  Confirmation was made at
the Okayama station by S. Nishimura, Y. Ando and A. Okazaki on Jan.
28.90 UT, when UBV photometry indicated differences dV = -0.5, dB =
-0.4, dU = -1.3 in the sense nova minus BD +2 3877 (= SAO 124601,
nominally mv ~ 8.0).  A spectrogram obtained on Jan. 29.90 UT
showed H-beta emission.

     J. Mattei, American Association of Variable Star Observers,
communicates the following additional confirmations and visual
magnitude estimates (with respect to BD +1 4004 = SAO 124651, mv =
7.4): Jan. 29.45 UT, 7.7 (P. Collins, Cambridge, MA); 29.56, 7.8
(J. Morgan, Prescott, AZ); 30.46, 8.1 (Collins); 30.56, 8.1
(Morgan); 31.56, 8.7 (Morgan).

     J. Maza, Department of Astronomy, University of Chile, reports
the discovery, by M. Wischnjewsky, of a possible supernova 14" west
and 1" north of the nucleus of the galaxy MCG -5-28-17 (R.A = 11h55m.5,
Decl. = -28o46', equinox 1950.0).  On Jan. 19 the star had mpg = 16.5.

     N. D. Hulkower writes: "This minor planet, one of several
near-earth objects for which feasible missions to rendezvous with a
spacecraft have been identified, is currently well placed for
observation (ephemeris in Efemeridy Malkyh Planet for 1981, p. 232; for
1982, p. 241).  Observers are urged to obtain data to determine or
confirm the composition, size and shape, possible binary nature,
rotation rate, location of the pole, etc.  High-quality astrometric
observations will also be useful.  For further information, contact
me at: Jet Propulsion Laboratory, 156-204, 4800 Oak Grove Drive,
Pasadena, CA 91109, U.S.A."

1982 February 1                (3661)              Brian G. Marsden
