Blondin et al. add that a spectrum (range 350-740 nm) of SN 2006da (cf. CBET 545), obtained on June 17.46 by Calkins, shows it to be a type-Ia supernova around one week past maximum light. Adopting the NED recession velocity of 12345 km/s (catalogue redshift from the Sloan Digital Sky Survey) for the host galaxy (whose 2MASX position is given as R.A. = 23h27m48s.7, Decl. = +14d28'31", equinox 2000.0), the maximum absorption in the Si II line (rest 635.5 nm) is blueshifted by 12000 km/s.
