PROBABLE NOVA IN CYGNUS
     H. Kosai, Tokyo Astronomical Observatory, reports the discovery
by M. Wakuda of a probable nova, located near CI Cyg at R.A. =
19h52m7, Decl. = +35deg33' (equinox 1950.0).  Magnitudes (Tri-X with
green filter): June 26, [13; July 28.6 UT, 13; Aug. 4.72, 9.4.  M.
Huruhata reports no evidence of this object on about 500 films
taken by him since 1979 and gives V = 8.7, B = 9.5 on Aug. 8.87 UT.


1986 PA
     E. Helin, Jet Propulsion Laboratory, reports her discovery of
a fast-moving asteroidal object on exposures by C. Wilson and herself
(assisted by R. Day and J. Mueller) with the 1.2-m Schmidt in
the course of Palomar Sky Survey II.  Measurer: M. Rudnyk.
