     William A. Bradfield, Dernancourt, near Adelaide, reports the
discovery of his twelfth comet as shown below.  The object is
diffuse without condensation, and nothing was reported about a tail.

          1984 UT          R.A. (1950.0) Decl.       m1

     E. P. Aksenov, Sternberg Astronomical Institute, cables that
G. N. Kimeridze, Abastumani Observatory, discovered a supernova 5"
east and 25" north of the nucleus of NGC 4419 (R.A. = 12h24m4, Decl. =
+15deg19'; equinox 1950.0) and of mpv = 16 on Jan. 4.096 UT.

2CG 195+04 = 'GEMINGA'
     J. P. Halpern, California Institute of Technology; J. E.
Grindlay, Center for Astrophysics; and G. F. Bignami and P. A.
Caraveo, IFC/CNR Milan, report that measurement of a CCD image
obtained at the prime focus of the 5-m telescope by J. Kristian
and J. Mould on 1983 Nov. 3 yields the position R.A. = 6h30m59s37,
Decl. = +17deg48'30"2 (uncertainty +/- 0"5, equinox 1950.0).
Reexamination of the CFHT CCD image of 1983 Apr. 15 gives a position
that is consistent within the quoted error; the position reported by
Lecacheux et al. (IAUC 3892) appears to be incorrect.  Photometry
with the Palomar 1.5-m telescope gives V = 21.0 +/- 0.2, B-V = +0.7,
V-R = +0.8, in agreement with estimates by Caraveo et al. (1984,
Ap.J. Lett. Jan. 15) based on the CFHT images.

     Further visual magnitude estimates by J. Bortle, Stormville,
NY: 1983 Sept. 11.4 UT, 13.9; Oct. 7.3, 13.9; 30.1, 14.1.

     Visual magnitude estimates by M. Verdenet, Bourbon-Lancy,
France: 1983 Dec. 1.8 UT, 15.4; 4.7, 15.3; 7.7, 15.5; 10.8, 15.4.

1984 January 9                 (3907)              Brian G. Marsden
