SUPERNOVAE 2009ie IN NGC 1093

Further to CBET 1897, I. Kleiser, S. B. Cenko, W. Li, and A. V.
Filippenko, University of California, report the LOSS discovery of an
apparent supernova on unfiltered KAIT images:

 SN       2009 UT       R.A. (2000.0) Decl.      Mag.      Offset
 2009ie   July 24.47   2 48 13.90  +34 24 52.8   19.3    27".3 W, 19".2 S

Additional KAIT magnitudes for 2009ie:  a co-added image from Sept.-Dec.
2008, [20.5; 2009 July 28.46, 19.5.
J. Fynbo and J. Sollerman, Dark Cosmology Centre, Niels Bohr Institute,
Copenhagen University, report on spectroscopy of 2009ie obtained with the
Nordic Optical Telescope (+ ALFOSC; range 360-850 nm, resolution 1.5 nm)
on Aug. 19.23 UT by M. Friis, B. Gullberg, J. Mortensen, and M. Strandet
(students at Copenhagen University).  The reduced spectrum of 2009ie
displays numerous strong P-Cyg profiles, and cross-correlation with a
library of supernova spectra using the "Supernova Identification" code of
Blondin and Tonry (2007, Ap.J. 666, 1024) shows it to be a type-IIP supernova
about 1-3 months past maximum.
