The Palomar Transient Factory (ATEL #1964; http://www.astro.caltech.edu/ptf/ ) independently detected SN2010kp (CBET#2577, Nakano et al.) as PTF10abpr on UT 2010 November 30.326 at R=17.8. The location of the transient, RA(J2000) = 04:03:38.7 and DEC(J2000) = +70:45:16.0 is offset by 11.6"W, 3.6"N from the galaxy ZOAG G137.54+13.56 identified by a visual search of the supergalactic plane (Hau et al. 1995). Spectra were obtained using the Double-Beam Spectrograph (DBSP; Oke \& Gunn 1982, PASP, 94, 586) on the Palomar 5-m Hale Telescope on December 6 UT and on December 13 UT. The superfit program (Howell et al. 2005, ApJ 634, 1190) finds a good match to the type II SN SN1999em. We derive a redshift of z=0.005, corresponding to a distance of 20 Mpc (assuming standard cosmology, Ho = 71 km/s/Mpc).
