SUPERNOVA 2009fk IN NGC 7364
N. Morrell and M. Phillips, on behalf of the Carnegie Supernova Project,
report that they obtained a spectrum (range 340-910 nm) of 2009fk (cf. CBET
1823) on June 2.36 UT with the 6.5-m Magellan II (Clay) telescope (+ MagE),
which reveals that this is a type-Ia supernova several weeks past maximum
brightness. Comparison with a library of supernova spectra via the Supernova
Identification code (Blondin and Tonry 2007, Ap.J. 666, 1024) shows that
2009fk is very similar to supernova 1994D at an age of 54 days after maximum
light.
