                    NOVA URSAE MINORIS 1956

     This recently discovered object (s. Inf. Bull. on Var. Stars
No. 18/19; MVS 731/733) had an outburst as a Nova in September
1956 but, according to an information by Kukarkin, it was again
fainter than 16m on December 14, 1962. In order to confirm its
present brightness and its spectral type several plates were taken
with the Tautenburg Schmidt-Camera in the U, B, V-System, M 13
being used as a standard (A.J. 61, 1956, p. 254). The data of the 
expositions as well as the resulting magnitudes of the Nova, reduced to
equal zenithal distance, are arranged in the following list:


Colour  Plate    Emulsion     Filter      J. D.                 Mag.
Region                                             Exposition

  B     865   Astro-spezial    GG 13   243 8089.63   10 min.   16m.7
  U     934   Astro-spezial    UG 2        8142.50   20 min.   16m.35
  Y     942   Astro-pan        GG 11       8143.56   20 min.   17m.2
  B     947   Astro-spezial    GG 13       8146.43   10 min.   17m.0


      By means of the U-, B- and V-Magnitudes one gets the colour
indices (U-B) = -0.65 and (B-V) = -0.2. Supposing that the Nova did
not change its brightness during the exposure time, and assuming that
it is a main sequence star one can derive for the Nova the spectral
type B 3.
