SUPERNOVAE 2002km-2002ky
     M. Doi, University of Tokyo, on behalf of the Supernova
Cosmology Project (cf. IAUC 7971, plus V. Fadeyev, B. Lee, V.
Stanishev, and R. Vogel) and the Subaru high-redshift supernova
search group (N. Yasuda, N. Kashikawa, K. Motohara, T. Morokuma, K.
Sekiguchi, G. Kosugi, H. Furusawa, Y. Komiyama, T. Takata, M. Ouchi,
Y. Ohyama, and Subaru Observatory SXDS Project members), reports
the discovery of 13 spectroscopically confirmed supernovae found
with the Subaru telescope (+ Suprime-Cam) in the SDSS i' band.
None of the supernovae were present in reference images (limiting
mag about 26.6; S/N = 5 for 2" aperture) taken on 2002 Sept. 30 and
Oct. 1.  The supernovae spectra were obtained at the Gemini North
telescope (+ GMOS) on Nov. 6, 8, and 9; at the Keck II telescope (+
ESI) on Nov. 6, 7, 9, and 10; at the Very Large Telescope Yepun UT4
(+ FORS2) on Nov. 7-11; and at the Subaru telescope (+ FOCAS) on
Nov. 12.  Redshifts were obtained using either the host galaxy
spectrum (denoted in the table with an asterisk) or with template
spectrum fitting of a supernova.  SN 2002kr is in an elliptical
host galaxy; it -- together with SNe 2002km, 2002kn, and 2002ko --
have spectra consistent with that of a type-Ia supernova.  The
spectra of the other objects show broad (several tens of nm wide)
lines that are indicative of supernovae and allow the ruling out of
active galactic nuclei, but the low signal-to-noise and limited
wavelengths prevent definitive typing.
