SUPERNOVAE
     The Supernova Cosmology Project [cf. IAUC 6270, plus R. Knop
and P. Nugent at Cerro Tololo (CTIO); C. Lidman and M. Della Valle
at the European Southern Observatory (ESO); and B. Schaefer with
the WIYN telescope at Kitt Peak] report fourteen supernovae found
with the CTIO 4-m telescope in their High Redshift Supernova Search.
The last column indicates the discovery telescope:  (1) Keck; (2)
ESO 3.6-m reflector.

The supernovae were all discovered before or at maximum light, they
were observed on Jan. 8-11 at CTIO and WIYN, and the supernova
spectra were obtained at the Keck telescope on Jan. 12-13 and the
ESO 3.6-m telescope on Jan. 13.  The redshifts were determined from
host-galaxy emission and absorption lines, except for those marked
with an asterisk, which were determined solely from the spectra of
the supernovae.  In all cases with either a measured host-galaxy
redshift or an adjacent-galaxy redshift (the latter indicated by
'*a'), the supernova redshift is consistent.  The supernovae are
all within 2".5 of the host-galaxy center.  Follow-up photometry
is being made in R and I for the twelve supervovae at z > 0.35, and in
V, R, and I for SNe 1997I and 1997N; finding charts are available
from saul@lbl.gov.
