SUPERNOVA 1990ae IN ANONYMOUS GALAXY
     J. Mueller reports her discovery of a supernova in an anonymous
galaxy at R.A. = 0h20m.3, Decl. = +6 33' (equinox 1950.0).  The
supernova (mag about 18) is located 13".4 east of the galaxy nucleus.
The red discovery plate was taken by Mueller and J. D. Mendenhall on
Oct. 15 UT with the 1.2-m Oschin Telescope in the course of the
second Palomar Sky Survey.  A spectrum obtained at the Hale 5-m
telescope (+ 4-shooter + spectrograph) by G. Djorgovski, D. Thompson,
and J. Smith shows a prominent, broad emission line coincident in
wavelength with the H-alpha and nitrogen emission from the galaxy
(redshift about 7680 km/s), indicating a probable type-II supernova.
