SUPERNOVA 1995M IN ANONYMOUS GALAXY
     R. H. McNaught, Anglo-Australian Observatory, reports his
discovery of an apparent supernova (magnitude R about 18.5) on a
plate taken by C. P. Cass with the U.K. Schmidt Telescope on Apr.
22.41 UT.  SN 1995M is at R.A. = 9h38m41s.78, Decl. = -12o20'07".9
(equinox 2000.0, uncertainty in both coordinates 0".3), which is
13" due west of the center of the edge-on host galaxy, near the tip
of the disk as recorded on the deep survey plate.  No star appears
at this position on earlier R or J exposures or on I plates taken
as late as 1994 Mar. 18.  A nearby star of mag about 19 has
position end figures 41s.84, 19'30".9.  P. Garnavich, A. Riess, and
R. Kirshner, Harvard-Smithsonian Center for Astrophysics, report
that P. Zhao obtained a CCD image on Apr. 24.3 UT with the 1.2-m
Mt. Hopkins telescope showing SN 1995M as a star of mag V = 18.2
+/- 0.1 at the western tip of an edge-on galaxy; it does not appear
on the Palomar Sky Survey prints down to a magnitude limit of about
20.
     B. Schmidt, Mount Stromlo and Siding Spring Observatories; and
R. Stathakis, Anglo-Australian Observatory, obtained a spectrogram
(range 360-740 nm) on Apr. 24.5 at the Anglo-Australian Telescope
that shows this object to be a type-Ia supernova about 15 days
after maximum.  The redshift of the host galaxy, measured from
narrow emission lines at the position of SN 1995M, is z = 0.052.


SUPERNOVA 1995D IN NGC 2962
     H. Mikuz, Ljubljana, reports additional CCD photometry (cf.
IAUC 6149) of SN 1995D:  Mar. 11.94 UT, V = 14.23 +/- 0.03, B-V =
+0.79 +/- 0.05; Apr. 3.78, 15.39 +/- 0.03, +1.25 +/- 0.05; 8.81,
15.59 +/- 0.03, +1.12 +/- 0.06; 17.81, 15.81 +/- 0.03, +1.05 +/-
0.06.
