              OKLAHOMA VARIABLE NUMBER 30

     Oklahoma Variable Number 30 was discovered in the 1950's
by Professor Balfour S. Whitney at the University of Oklahoma
Observatory. It is an eclipsing variable located at 8h 28m.1,

                       [FIGURE 1]

+3deg27' (1950). An unpublished investigation of the period was
conducted in 1967 by George F. Baird, Jr.

   ELEMENTS: Minimum = JD_{hel} 2430674.637 + 3d.387024E

     The points on the accompanying light curve were obtained
from observations of 15 minima between JD2430674 and JD2437285.
These measurements were carried out with a Cuffey Iris Photometer
using the comparison stars indicated on the chart whose 
photographic magnitudes for this investigation have been taken as:
a = 12m.2; b = 12m.5; c = 12m.8; d = 13m.4; e = 13m.5; and f = 13m.7.

                       [FIGURE 2]

The range of the variable is from 12m.7 to some magnitude less
than 13m.8. A plot of the step estimates from 448 plates
ranging from January 1942 to June 1962 revealed no secondary
minimum in the light curve.
