SUPERNOVA 2010ah
     E. O. Ofek, D. A. Howell, M. M. Kasliwal, A. Gal-Yam, J. S. Bloom, P.
Nugent, M. Sullivan, R. Quimby, S. B. Cenko, D. Poznanski, and S. R. Kulkarni,
on behalf of the "Palomar Transient Factory" collaboration, report their
discovery of a young, broad-line type-Ic supernova (magnitude R = 18.8) on
Feb. 23.504 UT.  The new object, designated 2010ah, is located at R.A. =
11h44m02s.99, Decl. = +55o41'27".6 (equinox 2000.0), which is about 5".2
from the galaxy SDSS J114402.98+554122.5 in p.a. 7 deg.  Nothing is visible
at this position in previous images of the same field taken on Feb. 19.439
(limiting magnitude R about 20.9).  A spectrum obtained by the queue
observing team (courtesy of the Gemini telescope staff) at the Gemini-North
telescope on Mar. 2, reduced and typed by Howell using the superfit spectrum
fitting code, resembles that of SN 1998bw at about three days prior to
maximum light (Galama et al. 1998, Nature 395, 670), and shows very broad
lines.  SN 2010ah is at z = 0.0498, based on the O II, H-alpha, H-beta, and
S II emission lines from the host galaxy.  A multi-wavelength follow-up
campaign is ongoing.
