SUPERNOVA 1994ak IN NGC 2782
     M. W. Richmond, Princeton University; and R. R. Treffers, S.
D. Van Dyk, and A. V. Filippenko, University of California at
Berkeley, confirm that there is a new starlike object in NGC 2782,
presumably a supernova, close to the position reported on IAUC 6122.
Observations were conducted as part of the Leuschner Observatory
Supernova Search, which uses an automated 0.76-m telescope equipped
with the Lawrence Berkeley Laboratory CCD camera.  The supernova (R
= 17.4 +/- 0.8) is located about 58" west and 33" south of the
galaxy's nucleus in an image obtained on 1994 Dec. 30 UT; it is
also barely visible in a mediocre image obtained on Dec. 23, but
not visible (upper limit R = 19) in a good image on Dec. 1.
     S. Nakano, Sumoto, Japan, forwards the following additional
unfiltered CCD magnitudes of SN 1994ak obtained with a 0.25-m
Schmidt-Cassegrain by Y. Kushida at Yatsugatake South Base
Observatory:  1994 Dec. 25.780 UT, 15.9; 28.591, 16.0; 29.619, 16.0;
31.616, 16.1; 1995 Jan. 1.645, 16.3; 2.600, 16.3.
     D. Balam, Climenhaga Observatory, Victoria, provides the
following magnitude and precise 2000.0 position for SN 1994ak
obtained on Jan. 3.44 UT:  V = 18, R.A. = 9h14m01s.47, Decl. =
+40o06'21".5; the supernova is indicated as being about 43" west
and 27" south of the galaxy's center.


SUPERNOVA 1994ai IN NGC 908
     M. Cavagna and E. Galliani, Sormano, Italy, report the
following precise position for SN 1994ai, obtained on Jan. 1.80
UT:  R.A. = 2h23m06s.17, Decl. = -21o13'58".3 (equinox 2000.0).


V1251 CYGNI
     This cataclysmic variable (cf. IAUC 5377) is evidently in
outburst, as indicated by the following visual magnitude estimates:
1994 Dec. 22.736 UT, [13.6 (P. Schmeer, Bischmisheim, Germany);
30.756, 13.3: (Schmeer); 31.713, 13.4 (L. Szentasko, Veresegyhaz,
Hungary); 31.833, 13.2 (Schmeer); 1995 Jan. 1.771, 13.7 (Schmeer).
The following precise position for V1251 Cyg has been measured
by B. Manning, Stakenbridge, England:  R.A. = 21h40m54s.36, Decl. =
+48o39'43".1 (equinox 2000.0).
