POSSIBLE NOVA IN VULPECULA
     S. Nakano, Sumoto, Japan, reports the discovery of a possible nova
(mag 9.5) by Hiroshi Abe (Yatsuka-cho, Matsue, Shimane-ken, Japan) on
several 30-s survey frames (limiting mag about 11.5) taken around Aug.
8.54 UT using a Canon EOS Kiss Digital Camera (+ 35-mm f/2.8 Pentax lens).
Nakano measured mag 9.4 and the following position for the new object from
Abe's JPEG image:  R.A. = 19h54m24s.3, Decl. = +20o52'47" (equinox 2000.0;
estimated uncertainty +/- 8").  Abe writes that nothing was visible on his
most recent frames taken on July 23, 31, and Aug. 4.  Nakano forwards the
following position for the new object measured by K. Kadota (Ageo,
Saitama-ken, Japan, 0.25-m f/5.0 reflector) from an unfiltered CCD image
taken on Aug. 8.682:  R.A. = 19h54m24s.64, Decl. = +20o52'51".9; mag 9.4
via reference stars in the Tycho-2 catalogue.  Kadota adds that a nearby
star of mag 11.8 on the same exposure has position end figures 23s.95,
30".3; he further notes that a star of red mag 18.1 and blue mag 17.6 in
the USNO-A2.0 catalogue has position end figures 24s.66, 51".7.
