SUPERNOVA 2009mv
Further to CBET 2090, A. J. Drake, S. G. Djorgovski, A. Mahabal, M. J.
Graham, and R. Williams, California Institute of Technology; M. Catelan,
Pontificia Universidad Catolica de Chile; E. C. Beshore and S. M. Larson,
Lunar and Planetary Laboratory, University of Arizona; and E. Christensen,
Gemini Observatory, report the CRTS discovery of a supernova in unfiltered
Catalina Sky Survey (CSS) images:
SN 2009 UT R.A. (2000.0) Decl. Mag. Offset
2009mv Dec. 16.32 7 15 39.74 +35 14 28.5 17.4 1".1 E, 4".6 S
Nothing was visible at this position on a CSS image from Nov. 25.43 UT
(limiting mag 18.5). A spectrogram (range 390-800 nm) of 2009mv was
obtained with the Palomar 5-m reflector (+ DBSP) on Dec. 19.35; cross-
correlation with a library of supernova spectra using the "SuperNova
IDentification" code (Blondin and Tonry 2007, Ap.J. 666, 1024) shows 2009mv
to be most similar to the peculiar type-Ia supernova 2006gz at five days
past maximum light.
C. V. Griffith, J. J. Kong, I. K. W. Kleiser, and A. V. Filippenko,
University of California, Berkeley, report that inspection of a CCD spectrum
(range 360-1000 nm), obtained on Dec. 18 UT with the 3-m Shane reflector (+
Kast) at Lick Observatory, also shows that 2009mv is a type-Ia supernova
within a few days of maximum brightness.
