The Palomar Transient Factory
(ATEL#1964) observed a broad-line type-Ic SN, PTF 10bzf, on UTC 2010 Feb 23.504 at R=18.8. The SN
was not seen in previous images of the same field taken on 2010 Feb 19.439 to a limiting
magnitude R > 20.9. The SN coordinates are: 11:44:02.99 +55:41:27.6 (J2000),
about 5.2" at position angle of 7 deg from the galaxy SDSS J114402.98+554122.5.
We obtained a spectrum using Gemini-N GMOS on 2010 Mar 01.
The spectrum resembles SN 1998bw at about -3 days prior to maximum light
(Galama et al., Nature, 395, 670),
and shows very broad lines. The supernova is at z=0.0498, based on
the OII, H\alpha, H\beta and SII emission lines from the host galaxy.
We thank the Gemini staff for queue-serviced observing.
A multiwavelength follow-up campaign is ongoing.
