SUPERNOVA 2006eb IN UGC 771
     D. C. Leonard, P. M. Nied, and M. R. Davis, San Diego State
University; T. R. Norris, California State University, Chico; and
M. R. George, Harvard-Smithsonian Center for Astroophysics, report
on behalf of the Caltech Core-Collapse Project (cf. IAUC 8405) that
a CCD spectrum (range 460-910 nm) of SN 2006eb (cf. CBET 590),
obtained on Aug. 2 UT with the double spectrograph mounted on the
Palomar Observatory 5-m Hale telescope, shows it to be an aging
type-Ia supernova.  When corrected for the redshift of the probable
host galaxy, UGC 771 (cataloged redshift of z = 0.017 from the Sloan
Digital Sky Survey), it exhibits spectral features very similar to
those of SN 1994D at 44 days after peak brightness (cf. Filippenko
1997, ARAA 35, 309), although one emission feature, near 490 nm, is
noticeably weaker in the spectrum of SN 2006eb.
     A. V. Filippenko, M. Moore, and T. N. Steele, University of
California, Berkeley, report that inspection of CCD spectra (range
330-1040 nm), obtained on Aug. 2 UT with the Shane 3-m reflector (+
Kast spectrograph) at Lick Observatory, shows that SN 2006eb is of
type Ia, very roughly 6 weeks past maximum brightness.
