SUPERNOVA 2006ay
     A. V. Filippenko and R. J. Foley (University of California, Berkeley)
report that inspection of a CCD spectrum (range 320-920 nm), obtained on
Apr. 27 UT with the Keck I 10-m telescope (+ LRIS), shows that SN 2006ay
(cf. IAUC 8691) is a type-Ia supernova, about 2 months past maximum
brightness.  The recession velocity of the host galaxy, measured from
narrow emission lines in a superposed H II region, is about 26000 km/s --
a factor of six larger than the average recession velocity of the four
main galaxies of Seyfert's Sextet (4300 km/s), and exceeding the velocity
of its discordant component (19800 km/s).
