     C. Pollas, Observatoire de la Cote d'Azur (OCA), reports his
discovery of an apparent supernova on Technical Pan films (limiting
mag about 21.5) obtained on Jan. 6.00 and 9.06 UT with the OCA 0.9-
m Schmidt telescope.  Then at magnitude V about 19.0, SN 1995B is
located at R.A. = 7h17m33s.82, Decl. = +21o49'25".0 (equinox 2000.0),
which is 2".8 west and 7".3 south of the galaxy's center.  On Feb.
7.0, the supernova is still present but about 1 mag fainter than in
early January.  A nearby star of mag 16 has position end figures
34s.72, 58".6.  The limiting magnitude of the discovery film is
about 21.5.  Nothing is visible at the location of SN 1995B on
films of limiting mag 22 obtained at OCA in 1989 Dec. and on 1990
Nov. 26.1.

     K. Honeycutt and J. Robertson, Indiana University (IU), write:
"KR Aur occasionally falls from its high state of V = 12-13 to
17-18.  The IU Roboscope shows no low states during 1991-94 (347
observations), but over the last 100 days, KR Aur has faded
smoothly to V = 16.5 and is still falling."

SUPERNOVA 1993J in NGC 3031
     A. P. S. Crotts, Columbia University, reports:  "SN 1993J is
accompanied by a companion at radius 0".84 +/- 0".09 and position
angle 344 +/- 9 deg from the supernova, consistent with the north-
south elongation seen in pre-explosion images of the progenitor
(IAUC 5758).  The data were obtained at the Canada-France-Hawaii
Telescope on 1994 Dec. 30 UT in two medium-width bands at 684 and
819 nm, with the FWHM of images as good as 0".60.  No structure
besides the two point sources is seen.  The magnitude of the
companion, based on these bands, is I about 22.7 (R-I about 0.5;
uncertainties of about 0.2 mag).  The companion will affect late-
time photometry of the supernova."

     Visual magnitude estimates:  Feb. 1.934 UT, 8.6 (T. Cooper,
Benoni, S. Africa); 2.063, 8.1 (D. Overbeek, Edenvale, S. Africa);
3.853, 8.9 (L. A. G. Monard, Pretoria, S. Africa); 4.951, 8.8
