Spectroscopic confirmation was obtained with the Palomar 5-m reflector (+ DSBS) on Jan. 16 UT; a spectrogram (range 400-800 nm) was compared with a library of spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024), showing that 2011kd best matches the type-Ia supernova 1994D at two weeks past maximum.
