PROBABLE NOVA IN M31
J. Bryan, Austin, Texas, reports the discovery by M. Brewster
and himself of a probable nova in M31. The object was recorded
on 1982 Dec. 16.2 UT at mag ~ 17.2 and confirmed an hour later.
It is located at R.A. = 0h39m34s, Decl. = +40deg45'05" (equinox
1950.0), between the Hodge dust clouds D-298 and D-267.
1982 YA
F. Dossin, Institut d'Astrophysique, Liege, provides the
following precise positions of the object reported on IAUC 3758. G.
Sause assisted with the observations (at Haute Provence).

The following uncertain orbital elements, by the undersigned,
are from the above observations, which can be satisfied
by Amor-type orbits with e in the range 0.4-0.8. The ephemeris
ought not to be in error by as much as 1 degree. Further
observations, including possible prediscovery ones, are urgently
desired.
