SUPERNOVA 2013ah = PSN J09443380+5545444
     J. M. Silverman, University of Texas; J. Vinko, University of Szeged; R.
Quimby, Kavli IPMU, University of Tokyo; and J. C. Wheeler and E. Chatzopoulos,
University of Texas, write that a spectrogram, obtained on Mar. 1.14 UT with
the 9.2-m Hobby-Eberly Telescope (+ Marcario Low-Resolution Spectrograph) by
S. Rostopchin, shows that PSN J09443380+5545444 = SN 2013ah (cf. CBET 3430) is
a type-Ia supernova.  Correlation with a library of supernova spectra using
the "SuperNova IDentification" code (SNID; Blondin and Tonry 2007, Ap.J. 666,
1024) indicates that PSN J09443380+5545444 = SN 2013ah is a normal type-Ia
supernova at maximum brightness.  After removal of the host-galaxy recession
velocity of 7362 km/s (from narrow emission lines), the absorption minimum of
the Si II 635.5-nm line is found to be blueshifted by about 11300 km/s.
