SUPERNOVA IN NGC 1365
     P. O. Lindblad, Stockholm Observatory, and P. Grosbol, European
Southern Observatory, report the following position and magnitudes
obtained using a CCD on the 2.2-m telescope at La Silla on
Nov. 27.17 UT: R.A. = 3h31m37s08, Decl. = -36deg18'56"2 (equinox 1950.0):
V = 13.8, B-V = +0.9.  This was apparently an independent discovery.


V0332+53
      R. W. Argyle, Royal Greenwich Observatory, telexes the
following accurate position of a star of mpg = 16.5 measured on a
plate taken on Nov. 23.757 UT: R.A. = 3h31m14s85, Decl. = +53deg00'24"5
(equinox 1950.0).  This is the only star on the blue and red Palomar
Sky Survey plates to fall within the +/- 15"  error box of the
EXOSAT position given on IAUC 3893.

     K. Kodaira, Tokyo Astronomical Observatory, telexes that his
observations with the 1.9-m reflector at Okayama show the star at
V = 15-16 with an emission-line nova-like spectrum on an
interstellar-absorbed blue continuum (370-670 nm).

     P. L. Bernacca, T. Iijima and R. Stagni, Asiago Astrophysical
Observatory, telex that faint H-alpha emission is present on two Asiago
spectrograms obtained on Nov. 29 and 30.  Rough photometry gives V
= 14.6, B-V = +2.4; since no absorption bands characteristic of M-
type stars are observed, the object is heavily reddened.  Any
modulation in V had an upper limit of 0.4 mag over timescales from 1
second to several minutes around Dec. 2.03 (simultaneously with
EXOSAT observations) and 2.98 UT.
