SUPERNOVA 2010iw NEAR UGC 4570
     Stanley C. Howerton, Arkansas City, KS, U.S.A.; A. J. Drake, S. G.
Djorgovski, A. Mahabal, M. J. Graham, and R. Williams, California Institute
of Technology; J. L. Prieto, Carnegie Observatories; M. Catelan, Pontificia
Universidad Catolica de Chile; E. C. Beshore and S. M. Larson, Lunar and
Planetary Laboratory, University of Arizona; and E. Christensen, Gemini
Observatory, report the discovery by Howerton of an apparent supernova in
public Catalina Sky Survey (CSS) images:

 SN       2010 UT       R.A. (2000.0) Decl.      Mag.      Offset
 2010iw   Oct. 14.66   8 45 15.01  +27 49 21.8   16.4    12".9 W, 3".4 S

Further magnitudes for 2010iw:  June 11.16 UT, [19.0 (CSS); Oct. 17.50,
16.3 (Howerton, remotely with a 0.6-m LB-1 telescope, Rodeo, NM, U.S.A.).
They note that the new object lies 5".4 east and 1".1 north from a galaxy
seen in Sloan Digital Sky Survey images with measured redshift z = 0.109;
the current luminosity of 2010iw appears too high for it to be a regular
supernova associated with this distant galaxy.  The host galaxy is thus is
likely to be UGC 4570 (at redshift z = 0.0215).
