SUPERNOVAE
B. Szeidl, Konkoly Observatory, cables that M. Lovas has discovered
a supernova 15" east and 10" north of the center of NGC
4874 (R. A. = 12h57m.2, Decl. = +28o14', equinox 1950.0). The object was
observed on June 2 at mpg = 15.
C. Torres, Department of Astronomy, University of Chile, telexes
that E. Gonzalez has discovered a probable supernova located
1" west and 11" north of the center of an anonymous galaxy at R. A. =
12h47m56s.94, Decl. = -9o10'43".0 (equinox 1950.0). On May 30.089 UT the
object was at mpg = 15.
PU VULPECULAE
A. Purgathofer and A. Schnell, Institute for Astronomy, University
of Vienna, report further photoelectric data for this object
(cf. IAUC 3604) obtained at the Figl Observatory: May 21.03 UT, V =
9.53, B-V = +0.83, U-B = +0.53; June 3.00, 9.30, +0.84, +0.54.
J. A. Mattei, AAVSO, communicates that this object continued
to decline (cf. IAUC 3487) until 1980 mid-Sept., and provides the
following mean visual magnitude estimates by AAVSO members: 1980
July 4, 12.7; 29, 13.1; Aug. 23, 13.5; Sept. 17, 13.7; Oct. 12,
13.3; Nov. 6, 13.0; Dec. 1, 13.0; 26, 12.9; 1981 Jan. 20, 12.5; Feb.
14, 12.3; Mar. 11, 12.0; Apr. 5, 11.5. She also provides the following
recent individual estimates: Apr. 13.5 UT, 11.0 (T. Langhans,
San Bruno, CA); 23.5, 10.6 (Langhans); 29.5, 10.2 (Langhans); May
7.2, 9.8 (E. Mayer, Barberton, OH); 17.5, 9.5 (Langhans); June 1.16,
9.4 (Mayer); 1.18, 9.7 (J. Bortle, Stormville, NY).
POSSIBLE METEOR SHOWER
J. D. Drummond, Department of Astronomy, New Mexico State
University, writes that comet 1964 VIII (Ikeya) is a likely parent
body of the epsilon Geminid meteor shower of October, and that a stronger
pre-dawn shower is predicted between about June 25 and July 9, the
dates of minimum post-perihelion approach to the earth of the orbits
of the epsilon Geminids (with theoretical radiant R.A. = 19o, Decl. = +8o)
and comet 1964 VIII (R.A. = 31o, Decl. = +9o), respectively (cf. Drummond
1980, Icarus 41, in press). Favorable conditions will occur for
searching for these meteors this year, with new moon occurring on
July 1.8 UT.
