Supernovae 2009ju, 2009jx, and 2009ka.
CHALLIS P. and TANG S.
Abstract (from CDS):
P. Challis, Harvard-Smithsonian Center for Astrophysics (CfA), on behalf of the CfA Supernova Group, reports that a spectrum (range 330-850 nm) of 2009ka (cf. CBET 1985), obtained on Oct. 21 UT by S. Tang with the F. L. Whipple Observatory 1.5-m telescope (+ FAST), shows it to be a type-IIb 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 2009ka best matches type-IIb supernovae.
