The Nearby Supernova Factory reports the classification of supernova SN 2010hb (CBET 2424). A spectrum (range 320-1000 nm) obtained Aug 27.5 UTC with the SuperNova Integral Field Spectrograph (SNIFS) on the University of Hawaii 2.2-meter telescope reveals SN 2010hb to be a young Type II SN, estimated at 1-2 weeks after explosion. Broad H-alpha, H-beta and He I 5876 emission (not yet developed into clear P-Cygni profiles) is seen at wavelengths consistent with the 4997 km/s redshift (RC3) of the host galaxy, UGC 02537. There is strong Galactic extinction, A_V = 0.766 (Schlegel, Finkbeiner and Davis, 1998, ApJ 500, 525), along this sightline.
