SUPERNOVA 1996X IN NGC 5061
     G. J. Garradd, Loomberah, Australia, and S. Nakano, Sumoto,
Japan, report the independent discoveries of an apparent supernova
in NGC 5061 by Robert O. Evans (Coonabarabran, N.S.W., on Apr. 12.5
UT, mag about 13, visual) and by Kesao Takamizawa (Saku-machi,
Nagano-ken, on Apr. 12.618, mag 13.5, T-Max 400 film), respectively.
R. and Y. Kushida (Yatsugatake) report the following precise
position for SN 1996X from a CCD frame exposed on Apr. 13.480: R.A.
= 13h18m01s.13, Decl. = -26o50'45".3 (equinox 2000.0; mag 14.0),
which is about 52" west and 31" south of the galaxy's center.  From
a CCD exposure on Apr. 13.443, Garradd provides a position for the
supernova with position end figures 01s.14, 46".0.  Evans reports
that no object was seen at this position on Mar. 24; Y. Kushida
reports that a patrol film (Technical Pan 6415, limiting mag 15.5)
exposed on 1993 Feb. 24 shows nothing at this position.
Furthermore, no object is present at this location on the digital
sky survey (field taken in May 1976).  A nearby field star of mag
about 16 has position end figures 03s.33, 30".5.


SUPERNOVA 1996W IN NGC 4027
     N. B. Suntzeff reports that spectrophotometry (range 370-730
nm) obtained by M.-T. Ruiz with the Cerro Tololo 4-m telescope on
Apr. 13.1 UT confirms that this is a type-II supernova near maximum
(cf. IAUC 6379), with a very blue continuum.  CCD images were
obtained by D. DePoy with the Cerro Tololo 0.9-m telescope,
yielding the following position (using the digital sky survey) for
SN 1996W:  R.A. = 11h59m28s.98, Decl. = -19o15'21".9 (equinox
2000.0), which is 17" west and 34" north of the nucleus of the
galaxy.  Provisional photometry gives V = 15.1 on Apr. 13.1.


COMET C/1995 O1 (HALE-BOPP)
     Visual m1 and coma-diameter estimates:  Mar. 23.50 UT, 8.6, -
(A. Hale, Cloudcroft, NM, 10x50 binoculars); 27.67, 7.9, - (D.
Seargent, The Entrance, NSW, Australia, 25x100 binoculars); 28.13,
8.5, 2'.6 (M. Plsek, Lelekovice, Czech Republic, 0.35-m reflector);
30.46, 8.2, - (Hale); Apr. 1.77, 7.3, about 8' (Seargent, 10x50
binoculars); 7.09, 8.3, 4'.5 (A. Baransky, Kiev, Ukraine, 0.11-m
reflector).
