     R. H. McNaught, Siding Spring Observatory, reports his discov-
ery of a fast-moving asteroidal object on an exposure by M. J.
Drinkwater with the 1.2-m U.K. Schmidt and his own subsequent obser-
vations of it with the 0.5-m Uppsala Southern Schmidt.  The images
on Nov. 13-16 are all faint and difficult to measure.
