Moore, D. S. Wong, D. Pooley, and A. V. Filippenko, University of California, Berkeley, report that inspection of CCD spectra (range 330-1040 nm), obtained on Oct. 24 UT with the Lick 3-m telescope (+ Kast), shows that 2006hn (IAUC 8758) is a type-Ia supernova and 2006iu (IAUC 8758) is a type-II supernova. SN 2006hn resembles a type-Ia event about a month after maximum brightness. Adopting the recession velocity of 6700 km/s for the host galaxy of 2006iu (measured from narrow emission lines), the minimum of the H-alpha absorption is found to be blueshifted by 7000 km/s. Filippenko adds: "Further to CBET 691, we have discovered that our initial wavelength solution was incorrect. Consequently, we have the following updates to values originally reported in CBET 691: Adopting a recession velocity of 5800 km/s for SN 2006gs (measured from narrow emission lines), the minimum of the H-alpha P-Cyg absorption is found to be blueshifted by 5600 km/s. Adopting the recession velocity of 6386 km/s for SN 2006kf (Huchra et al. 1999, Ap.J. Suppl. 121, 287), the minimum of the Si II 635.5-nm absorption is found to be blueshifted by 13400 km/s."
