Abstract (from CDS):
L. Tomasella, S. Valenti, P. Ochner, S. Benetti, and E. Cappellaro, Osservatorio Astronomico di Padova, Istituto Nazionale di Astrofisica; and A. Pastorello, Dipartimento di Astronomia, Universita di Padova, on behalf of a larger collaboration, report that a spectrogram (range 360-810 nm; resolution 2.2 nm) of PSN J22171952+3534500 = SN 2011fs was obtained on September 23.95 UT. The spectrum is that of a type-Ia supernova observed about one week before maximum. The velocity of the ejected material, as deduced from the position of the minimum of the Si II lines, is about 11600 km/s.
