SUPERNOVAE 2005ki AND 2005kj
     The "Nearby Supernova Factory" collaboration (C. Bonnaud and

discovery of a supernova (mag approximately 16.3, calibrated to R)
in images obtained on Nov. 17.5 UT with the QUEST II camera on the
Palomar Oschin 1.2-m Schmidt in the course of the NEAT program (cf.
CBET 263).  SN 2005kj is located at R.A. = 8h40m09s.18, Decl. =
-5o36'02".2 (equinox 2000.0).  A spectrum (range 320-1000 nm),
obtained Nov. 20.6 with the Supernova Integral Field Spectrograph
(SNIFS) on the University of Hawaii 2.2-m telescope, shows 2005kj
to be a type-IIn supernova at a redshift of z = 0.016, exhibiting
H-alpha (FWHM 1300 km/s), H-beta, H-gamma, and He I 587.6-nm in
emission.  The observed redshift is consistent with that of the
host galaxy (2MASX J08400884-0536039, z = 0.01698; Jones et al.
2005, The 6DF Galaxy Survey Data Release 2).
     A spectrogram of SN 2005ki (CBET 294), obtained Nov. 20.6
with SNIFS, shows it to be a young, blue type-Ia supernova.  The
spectrum is similar to that of SN 1994D at an age of -9 days with
respect to maximum, at a redshift consistent with that of the host
galaxy, NGC 3332 (z = 0.019607; Falco et al. 1999, PASP 111, 438).
