Andrew Howell, Iair Arcavi, Curtis McCully, Stefano ValentiLCOGT SN-KPSN Ia0.034LCOGT SN-KPFrom extended H-alpha emission in the 2D spectrum, we derive a redshift of z=0.034 for the host galaxy. At this redshift, the absolute magnitude at discovery was M_V = -19.0 mag. Using Superfit (Howell et al. 2005, ApJ, 634, 1190), we find a good fit to the normal Type Ia SN 2002bo 1 day before maximum light.
