PROBABLE NOVA IN AQUILA
     H. Kosai, Tokyo Astronomical Observatory, telexes that Minoru
Honda, Kurashiki, has discovered an object, presumably a nova, at
R.A. = 19h14m1, Decl. = +3deg39' (equinox 1950.0).  The object faded from
mv = 10 on Dec. 2.40 UT to mv = 12 on Dec. 7.  It could not be
found on a plate taken on Nov. 29.
