SUPERNOVA 1989G IN MCG +2-29-11
     J. Mueller and C. Brewer report their discovery of a supernova
located 18" east and 18" south of the center of MCG +2-29-11
(R.A. = 11h11m12s, Decl. = +9 52'00", equinox 1950.0).  The supernova
appears at mag 20 on the Apr. 5 discovery plate, taken in the
course of the Palomar Sky Survey II with the 1.2-m Oschin Schmidt
Telescope.  On Apr. 7, A. Picard measured Gunn r = 18.1 with the
1.5-m Palomar reflector (+ CCD).  A spectrum taken by J. Gunn and
B. Oke on Apr. 7 with the Hale 5-m reflector (+ 4-shooter spectrograph)
indicates that the object is a type-I supernova 20 days past
maximum with high H-alpha (magnitude r = 18.9).  The galaxy redshift
is 0.027.


A0535+26
     F. Makino and the Ginga Team, Institute of Space and Astronautical
Science, telex:  "The x-ray astronomy satellite Ginga has detected
x-ray activity from the transient x-ray source A0535+26 on Mar. 28
with the All Sky X-ray Monitor (ASM).  The intensities are 0.25 Crab
on Mar. 28.24 and 0.33 Crab on Mar. 30.30 UT in the energy range 1 to
6 keV."
