SUPERNOVAE 2009V AND 2009ae
     R. Chornock, D. A. Perley, and J. S. Bloom, University of California,
Berkeley, report that inspection of spectra (range 310-925 nm) obtained on Feb.
19.61 UT with LRIS on the Keck-I 10-m telescope reveals that 2009V (cf. CBET
1680) is a type-Ia supernova; cross-correlation with a library of supernova
spectra using the "SuperNova IDentification" code (SNID; Blondin and Tonry
2007, Ap.J. 666, 1024) indicates that the redshift is 0.093 +/- 0.003 and that
2009V is 10.5 +/- 1.1 days after maximum light.  Spectra obtained on Feb.
19.68 of 2009ae (cf. CBET 1696) reveal that it is also a type-Ia supernova;
SNID finds a best match with SN 1999ee at an age of 20 days after maximum
light.
