SUPERNOVA 2009ap IN ESO 138-27
     M. Stritzinger, N. Morrell, and F. Salgado, on behalf of the Carnegie
Supernova Project, report they obtained a spectrogram (range 402.7-1011 nm)
of 2009ap (cf. CBET 1712), obtained on Mar. 16.1 UT with the Magellan I BAADE
(+ IMACS) telescope, appears to be that of a type-Ic supernova several weeks
past maximum.  Adopting a host-galaxy recession velocity of 6230 km/s (H I
Parkes All-Sky Survey Final Catalog; Wong et al. 2006, MNRAS 371, 1855) for
the host galaxy (ESO 138-27), Fe II (rest 516.9 nm) and O I (rest 777.4 nm)
are measured to be blue-shifted by roughly 5600 and 6700 km/s, respectively.
