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.
