  ACCURATE POSITION AND PRE-NOVA IDENTIFICATION FOR
               NOVA CEPHEI 1971

     Nova Cephei 1971 was observed with the 26-inch
refractor at Leander McCormick Observatory. A plate was
taken on July 29 for a position determination, and a plate
of one hour exposure was taken to aid in identifying the
pre-nova star in the Palomar Sky Survey. The position was
determined to be R.A. (1950.0) = 22h02m46.85s+-0.01s Dec.
(1950.0) = +53d15' 48.2"+-0.1".

                       [FIGURE 1]

      The accompanying enlargement of the Palomar Sky
Survey shows the location of the pre-nova star. The 
photographic magnitude of the pre-nova star was found to be
17.4+-0.2 as determined by measurement of its image 
diameter on the blue Palomar print (1).
