               BATESON'S NOVA Sgr 1969


In IBVS 389 (1969) F.M. Bateson announced the discovery of a nova in
Sagittarius. Estimates of the photographic magnitude have been made on 18
Nantucket plates taken during 1969, from J.D. 40382 to 40495. About 90 plates
from previous years, 1957-1968, and about 25 for 1970-1972 show the magnitude
to be fairly constant at about 13 mag. All of the magnitudes for the nova in

1969 are shown in the light curve, where dots represent the Nantucket
estimates, the open circles Bateson's. The finder chart shows the comparison
stars used here. Their adopted magnitudes, based on S.A. 158, are as follows:
a 6.4:, b 7.2:, c 9.4, d 10.4, e 11.4, f 12.7, g 13.2.
