SUPERNOVA 2010dd IN UGC 10594
     F. Ciabattari, M. Rossi, and G. Petroni, Borgo a Mozzano, Italy, report
their discovery of an apparent supernova (mag 17.2) on unfiltered CCD images
obtained on May 23.92 (limiting mag 19.0) and 24.87-24.91 UT (limiting mag
19.2) with a 0.5-m Newtonian telescope.  The new object is located at R.A. =
16h52m47s.60, Decl. = +51d03'45".7 (equinox 2000.0; astrometry with respect
to USNO-B1 stars), which is 8" west and 3" north of the center of the galaxy
UGC 10594.  Nothing is visible at this position on Palomar Sky Survey plates
from 1996 Mar. 16 (limiting mag 20.3, F plate) or 1989 June 28 (limiting mag
20.3, J plate).
