SUPERNOVA IN ANONYMOUS GALAXY
     Dr. B. Szeidl, Director of the Konkoly Observatory, Budapest,
cables that M. Lovas has discovered a supernova in an anonymous
galaxy at R.A. = 13h59m.5, Decl. = +54o40' (1950).  The supernova is
located 17" directly east of the galaxy's nucleus, and on June 11 was of
photographic magnitude 14.5.


RT LACERTAE
     D. M. Gibson, R. M. Hjellming and F. N. Owen, National Radio
Astronomy Observatory, report the detection of variable radio emission
from the eclipsing binary RT Lac.  The source was present on
all five days (1975 May 16-20) it was observed with the N.R.A.O.
interferometer, reaching levels of 0.029 Jy at 8085 MHz.  RT Lac and
the previously known radio binaries UX Ari and AR Lac are members of
a class of binaries for which RS CVn is the prototype.


COMET LONGMORE (1975g)
     A. J. Longmore, Siding Spring Observatory, cables his discovery
of a comet on a sky survey plate taken with the U.K. 122-cm Schmidt
telescope by P. R. Standen.

     1975 UT             R. A. (1950) Decl.
     June 10.63       18 54.0       -58 42
          11.58       18 53.0       -58 48
          11.67       18 52 54.0    -58 48 55

The third observation was made visually by A. J. Longmore and
P. Wallace on the Anglo-Australian 381-cm telescope.  Object diffuse
with some central condensation and a faint tail of 15".  Possibly
the magnitude is reported as 17, but a satisfactory interpretation
of the uncoded cable is difficult.


1975 June 13                   (2789)              Owen Gingerich
