S. Blondin, R. Kirshner, and P. Challis, Harvard-Smithsonian Center for Astrophysics report that a spectrogram (range 350-740 nm) of 2007hu (cf. CBET 1056), obtained by P. Berlind on Sept. 11.14 UT with the F. L. Whipple Observatory 1.5-m telescope (+ FAST), shows it to be a reddened type-Ia supernova around maximum light. Cross-correlation with a library of supernova spectra indicates that 2007hu is most similar to the type-Ia supernova 1999ej (cf. IAUC 7286, 7298) at one day before maximum. Adopting a recession velocity of 10637 km/s for the host galaxy (from The Updated Zwicky Catalog, http://tdc-www.harvard.edu/uzc/), the maximum absorption in the Si II line (rest 635.5 nm) is blueshifted by roughly 13500 km/s. Also, interstellar Na I D absorption at the redshift of the host galaxy is visible in the spectrum with an equivalent width of 0.6 nm.
