             A NOVA-LIKE VARIABLE STAR



  The star (1900: 23h44.0m, + 50d54') is Oklahoma Variable No. 29.
It was found in 1951 on plates taken in 1950. During the next four
years, 26 plates were taken with the 25 cm reflector, exposed to
Show stars fainter than 17m_pg. 
  Magnitudes of comparison stars were obtained from measures with
a Cuffey type astrophotometer of 4 pg plate pairs with Selected Area
20 as standard, and 5 pr plates using an unpublished sequence for
CS Cas, which is only 13' from the new variable. The pg magnitudes
are marked on the chart inset in the figure.

                          [FIGURE 1]

    Observations of OV29 and chart of surroundings (5' square). The
    vertical scale is for both pg and pr magnitudes. The symbols
    are: camera, pg: +; reflector, pg: [dot]; pr: [triangle].


   The observations in the figure indicate a maximum near JD2433600,
and an amplitude of 4.8 m_pg, from 12.3 to 17.1. The close agreement
of pg and pr points in maximum shows that the star is blue. The points
in minimum light are from estimates with an eyepiece. One point, 17.1m_pg,
at JD2435391.6, is beyond the limit of the figure.
   It is probable that the variable is a U Gem type star. No trace
of it could be seen on earlier plates on 241 nights from 1942 until
the 1950 outburst, nor on 9 later nights down to October, 1958. Most
of these had limiting magnitudes near 14.5, but a few near 16 m_pg.
