SUPERNOVA IN NGC 3226
     A. R. Klemola, Lick Observatory, reports that he has discovered
a supernova on plates taken by B. F. Jones with the 51-cm double
astrograph on 1976 Dec. 21.  The supernova, of blue magnitude 17,
is located 27" east and 22" north of the nucleus of the elliptical
galaxy NGC 3226 but is possibly associated with the neighboring
Seyfert galaxy NGC 3227.  The object was confirmed and at about the
same brightness on an exposure by E. A. Harlan on 1977 Jan. 13.


NOVA VULPECULAE 1976
     C. A. Whitney, Center for Astrophysics, provides the following
photoelectric observations, made with the 40-cm reflector at the
Harvard College Observatory's Agassiz Station.  Measures are relative
to HD 182293, for which the following values were determined
from observations on five nights: V = 7.18, B-V = +1.15.  These
data supersede earlier reports.
