PTF Discovery of a type II supernova in M 51.
SILVERMAN J.M., FILIPPENKO A.V. and CENKO S.B.
Abstract (from CDS):
Name | RA (J2000) | Dec (J2000) | Discovery | Mag | Redshift | Type
| Spec. | Phase | Instrument | Notes PTF11eon | 13 30 05.08 | +47 10 11.2 | Jun 01.19 | 13.5 | 0.002 | SN | Jun. 2 | | Keck I+ LRIS | exact magnitude uncertain due to saturation
The spectrum shows a relatively blue continuum, with well-developed P-Cygni profiles in the Balmer series. After removal of the host-galaxy recession velocity of 600 km/s (Rush, et al. 1996, ApJ, 473, 130), the minimum of the H-alpha absorption is blueshifted by about 17,600 km/s.
PTF is a collaboration of Caltech, LCOGT, the Weizmann Institute, LBNL, Oxford, Columbia, IPAC, and Berkeley.
