     PHOTOELECTRIC PHOTOMETRY OF NOVA VULPECULAE

On October 22 and 26, 1976 Nova Vulpeculae was photographed 
by G.A. Becker and C.R. Chambliss at Kutztown, Pennsylvania.
Photoelectric observations were made on 17 nights using the 46cm
Cassegrain reflector of the Kutztown State College Observatory.
The photomultiplier used was an EMI 62565A with standard  UBV
filters. Each of the following observations represents a nightly 
mean:

   As comparison stars the following were used. The magnitudes
and colors of these stars listed here were obtained by this 
investigator.

8 Vul   G6 III   5.81   +1.01   +0.84

   The most unusual trend in the observations of Nova 
Vulpeculae was the sharp decrease which occured on November 3-4.
This has been confirmed by other observers as well. Over the
two-month period covered by the observations listed above, a
mean decrease of between 0.04 and 0.05 mag. per day is indicated. 
According to the data listed by C. Payne-Gaposchkin (The
Galactic Novae, 1957) it can be classified as a moderately fast
nova. Nova Vulpeculae is strongly reddened, but this is to be
expected as its galactic latitude is only +1 deg.
