SUPERNOVA 1991aq IN ANONYMOUS GALAXY
Rob McNaught reports his discovery of an apparent supernova on a
red plate taken by P. McKenzie with the U.K. Schmidt Telescope on
Aug.18.75 UT. The supernova, of mag about 18, is situated at R.A. =
1h 53m 44s.6, Decl. = -81 52'46".1 (1950.0, uncertainty 0".5 in
each coordinate), or 5".3 west and 10".6 south of the nucleus of an
anonymous spiral galaxy. No star appears in this position on the
SERC J, R and I and ESO B surveys. A field star of mag about 17 is
situated closer to the nucleus (4".4 west, 3".6 north) at end
figures 45s.0, 31".9.
