       UBV OBSERVATIONS OF V603 Aql = NOVA Aql 1918
                     IN 1968 AND 1969



   A few UBV photoelectric observations were made of V603 Aql =
= Nova Aql 1918 in October 1968 and in June 1969 at the No. 4 16-inch
telescope of the Kitt Peak National Observatory. Observation and data
reduction procedures are described elsewhere (Landolt 1973a,b). The
mean error of a single observation is no more than +/- 0.02m in each 
instance. The observations are given in Table I wherein the heliocentric 
Julian Day times of observation are known within +/- 0.0005d.

Comparison with previous photoelectric measurements (Landolt 1968)
shows that the colors appear to remain virtually constant. The visual
magnitudes found herein are within the overall range of variation
known for this object (see, for instance, brightness estimates made
by members of the American Association of Variable Star Observers,
quoted in the AAVSO Circulars).
   Thanks are due the Director of the Kitt Peak National Observatory 
for the telescope time. This work was supported by the Louisiana
State University Council on Research.
