SUPERNOVA 1989P IN NGC 6636
     J. Mueller and D. Mendenhall report their discovery of
another supernova on a red plate exposed Sept. 3 UT with the 1.2-m
Oschin Telescope in the course of the Second Palomar Sky Survey.
The object (mag about 16.5) is located 9" west and 47" south of
the center of NGC 6636 (R.A. = 18h22m.0, Decl. = +66o36', equinox
1950.0).  A spectrum taken by S. G. Djorgovski and R. R. de
Carvalho with the Palomar 5-m Hale Telescope (+ 4-shooter
spectrograph) on Sept. 6 shows broad emission features, including
Balmer lines, indicating this to be a type-II supernova and
possibly peculiar.


1989 September 6               (4847)             Daniel W. E. Green
