Abstract (from CDS):

M. Catelan, Pontificia Universidad Catolica de Chile; A. J. Drake, S. G. Djorgovski, A. Mahabal, R. Williams, and M. J. Graham, California Institute of Technology; E. C. Beshore and S. M. Larson, Lunar and Planetary Laboratory, University of Arizona; and E. Christensen, Gemini Observatory, report the CRTS (cf. CBET 1766) discovery of a supernova in unfiltered Catalina Sky Survey (CSS) images:

---------------------------------------------------------------------------— SN 2008 UT R.A. (2000.0) Decl. Mag. ---------------------------------------------------------------------------— 2008iy Sep. 28.12 16 08 37.23 + 4 16 26.7 17.8 ---------------------------------------------------------------------------—

The CSS light curve, containing 184 observations between 2005 Apr. 4 and 2009 Apr. 16, shows the explosion occurred between 2007 June 18 and 2007 Oct. 13. The rising part of the light curve is seen to last approximately a year. Additional follow-up was obtained with the Palomar 1.52-m reflector with Gunn filters, yielding the following magnitudes: 2008 Oct. 29.12, g = 18.3, r = 17.2, i = 17.8, z = 17.2; 2009 Mar. 17.33, 18.5, 17.6, 18.2, 17.6; Apr. 18.24, 18.7; 17.8; 18.3; 17.8.
