SUPERNOVA 1995S IN NGC 4456
Robert H. McNaught, Anglo-Australian Observatory, reports his
discovery of a supernova (mag about 17.5) on an R survey film taken
by K. S. Russell with the U.K. Schmidt telescope (UKST) on July 3.4
UT.  A confirming unfiltered CCD image was obtained by
G.J.Garradd and McNaught with the 1.0-m reflector at Siding Spring
on July 6.
SN 1995S is located at R.A. = 12h27m53s.30, Decl. = -30o05'55".4
(equinox 2000.0, uncertainty 0".4 in each coordinate), which is 12"
east and 3" south of the center of NGC 4456.  SN 1995S is offset
from a star of mag 20 (clearly present on the ESO R and SERC J
surveys) by about 7" in p.a. 200 deg; this star and another
further south both lie on a spiral arm, and the supernova lies
inside this arm.  SN 1995S is not present on UKST R plates taken by
Russell on Feb. 7 (limiting mag 21) and May 28 (limiting mag 20),
nor on an I survey plate taken on Mar. 11 by M. J. Drinkwater;
likewise, no image appears at the given position on several ESO and
SERC B, J, R, and I survey films.  A nearby star of mag about 15.5
has position end figures 50s.88, 06'08".0.

V542 CYGNI
Tonny Vanmunster, Belgium e-mails via vsnet that he has
detected an outburst of the UGSS-type variable V542 Cygni:
1995 July 14.955UT, 13.8 (0.35-m reflector, seq: AAVSO).
Confirmation has been reported in CVC 46 when E.Broens reported
it at magnitude 13.7 on July 16.945UT.
