NOVA IN THE LARGE MAGELLANIC CLOUD
     Gordon Garradd, Tamworth, N.S.W., reports his discovery of a
nova in the Large Magellanic Cloud at R.A. =  5h36.0, Decl. = -70 23'
(equinox 1950.0) on Mar. 21.484 UT (hypered Kodak 2415 film, 0.067-
m f/4.5 camera).  Photovisual and visual magnitude estimates by
Garradd and B. Tregaskis, Mt. Elisa, Victoria:  Mar. 18.54 UT, [15;
21.484, 11.4; 21.492, 11.4; 22.47, 11.6; 22.50, 11.6 (Tregaskis).


SUPERNOVA 1988J IN ANONYMOUS GALAXY
     G. N. Salukvadze, Abastumani Observatory, telexes the discovery
by G. N. Kimeridze of a supernova (mpg = 17.0) on Mar. 14.89 UT
in an anonymous galaxy located at R.A. = 11h41.4, Decl. = +60 29' (equinox
1950.0); the object is 1" west and 8" south of the galaxy's center.


SUPERNOVA 1987A IN THE LARGE MAGELLANIC CLOUD
     S. M. Matz, National Research Council and Naval Research
Laboratory (NRC/NRL); G. H. Share, NRL; and E. L. Chupp, University of
New Hampshire (UNH), on behalf of their collaborators at NRL, UNH,
and the Max Planck Institute, Garching, write:  "The Gamma-Ray
Spectrometer on NASA's Solar Maximum Mission satellite continues to
monitor Co-56 line emission from the supernova.  During the given
observation intervals, the preliminary average fluxes (units 10E-4
photon/cm2/s) for the 847- and 1238-keV lines, respectively, are
(errors given parenthetically combine statistical and systematic
uncertainties):  1987 Aug. 1-Sept. 7, 8.6 (4.0), 5.1 (3.5); Sept.
27-Oct. 30, 6.2 (4.1), 11.0 (3.5); Nov. 16-Dec. 22, 5.8 (3.4), 8.8
(2.9); 1988 Jan. 8-Feb. 14, 3.9 (4.2), 2.2 (3.6).  Some fluxes have
been revised from earlier reports based on new analysis."
