     U. Thiele, Max-Planck-Institut fur Astronomie, telexes the
following semiaccurate positions of a comet discovered by him with
the Hamburg Schmidt telescope at Calar Alto:

         1985 UT             R.A. (1950.0) Decl.      m1

         Oct.  9.19097      5 55 18      +21 14.6     13
               9.21736      5 55 15      +21 15.5
              10.16180      5 52 51      +21 45.7

The images, trailed during the 10-min IIIa-F exposures, have a
starlike core surrounded by a coma ~ 25" in diameter.

     R. O. Evans, Hazelbrook, N.S.W., reports his discovery of a
supernova of mag 13.5 on Oct. 10.67 UT 60" east and 50" north of
the nucleus of NGC 1433 (R.A. = 3h40m4, Decl. = -47deg24', equinox 1950.0).
G. Thompson, Brisbane, Queensland, confirmed the discovery an hour
later but gave the offset as 70" east, 20" north.

     H. Kosai, Tokyo Astronomical Observatory, has informed us of
the discovery in 1983 Oct. by M. Wakuda (Ryuyo, Shizuoka) of a
possible nova of mag 10 on a Tri-X exposure on 1983 Feb. 19.  Further
exposures by Wakuda, as well as patrol films subsequently examined
by M. Honda, Kurashiki, show the object fading from mag 9.5 on Feb.
13 to 11.5 on Apr. 13.  The object was discovered independently in
1984 July by K. Ogura on an objective-prism plate taken on 1983
July 12 with the 0.51-m Schmidt at the Bosscha Observatory; plates
on July 8 and 9 confirmed the presence of emissions of H-alpha, [O I]
636-nm and [O I]/[S III] 630-nm, as well as a weak continuum.  The
object was photographed in 1984 July-Aug. at mag 16 by S. Fujino
and T. Tashiro, and an exposure with the Kiso Schmidt on 1984 Aug.
24 shows a faint emission-line object with H-alpha, H-beta and [O III] 501-
496-nm.  It is doubtful whether the object can be seen on the
Palomar Sky Survey, and it was not evident on a Bosscha exposure on
1982 July 27.  Kosai has measured the position as R.A. = 18h04m43s2,
Decl. = -28o49'53" (equinox 1950.0, uncertainty 5").  Further details
are given in Tokyo Astron. Bull. (Second Ser.) No. 273.
