SUPERNOVAE 2006ke IN UGC 3365
     V. Stanishev, Physics Department, Stockholm University, report that
a rather noisy spectrum of SN 2006ke (cf. CBET 682, 684), obtained on
Oct. 21.19 UT with the Nordic Optical Telescope (+ ALFOSC; range 340-900
nm) by E. Leitet and A. Blomkvist (Uppsala University), shows it to most
likely be a reddened subluminous type-Ia supernova around maximum light.
The spectrum is similar to that of SN 2003Y (a comparison by eye with a
plot at http://www.cfa.harvard.edu/oir/Research/supernova/spectra/
sn2003y-20030131.flm.gif.  Adopting recession velocity of the host galaxy,
5151 km/s (de Vaucouleurs et al., "Third Reference Catalogue of Bright
Galaxies"; via NED), the blue-shift of the Si II 635.5-nm line is about
10400 km/s.
