2004IAUC.8360....1F - IAU Circ., 8360, 1 (2004/June-0)
Supernovae 2004ci and 2004cr.
FOLEY R.J., GANESHALINGAM M. and FILIPPENKO A.V.
Abstract (from CDS):
R. J. Foley, M. Ganeshalingam, and A. V. Filippenko, University of California, report that CCD spectra (range 330-1000 nm), obtained on June 20 UT with the Shane 3-m telescope at Lick Observatory, show that SNe 2004ci (IAUC 8357) and 2004cr (IAUC 8359) are both of type II. The expansion velocities, derived from the minimum of H_beta for SNe 2004ci (recession velocity 4158 km/s from narrow H_alpha) and 2004cr (recession velocity 5055 km/s from narrow H_alpha), are 11813 and 8443 km/s, respectively.
