SUPERNOVAE
     P. Garnavich and P. Challis, Harvard-Smithsonian Center for
Astrophysics (CfA), on behalf of the High-Z Supernova Search Team,
report the discovery of five supernovae on CCD images taken with
the Victor Blanco 4-m telescope at Cerro Tololo by A. Clocchiatti,
R. Schommer, N. Suntzeff, A. Athey, and E. Turner on Mar. 15 and 16
UT.  Spectra of SNe 1996Q, 1996R, 1996T, and 1996U were obtained by
R. Kirshner and R. Jayawardhana (CfA) with the Multiple Mirror
Telescope (MMT) on Mar. 17 and 18.  A spectrum of SN 1996S was
obtained by L. Germany and B. Schmidt (Mount Stromlo and Siding
Spring Observatories) and R. Stathakis (Anglo-Australian
Observatory) with the Anglo-Australian Telescope on Mar. 24.
Results derived from the imaging and spectra are as follows:

SN      1996 UT     R.A.  (2000)  Decl.      R         Offset
1996Q   Mar. 15   8h46m09.18  + 0o06'53.9   21.8   0".6 W, 0".3 N
1996R   Mar. 15  11 16 10.36  - 0 11 39.3   20.6   2".6 E, 6".4 S
1996S   Mar. 15  11 25 11.16  -35 26 29.1   22.5   3".5 W, 1".3 N
1996T   Mar. 15  10 05 27.66  - 7 27 23.9   21     0.0, 0.0
1996U   Mar. 15  11 50 33.51  +10 26 45.4   22.2   0".5 W, 1".3 S

The redshifts and estimated supernova types are as follows:  SN
1996Q, z = 0.36, ?; SN 1996R, 0.15, Ia; SN 1996S, 0.11, II; SN
1996T, 0.24, Ia; SN 1996U, 0.43, Ia.  Narrow emission lines from
the host galaxies appear in spectra of SNe 1996Q, 1996T, and 1996U.
The redshift of SN 1996R is based on correlating broad features
with spectra of well-observed, low-redshift type-Ia supernovae.
The MMT spectra also show that an object of magnitude R = 21.0,
located 3".8 south of SN 1996Q, is a quasi-stellar object at z =
2.06.  Finder charts may be requested by sending electronic mail to
pgarnavich@cfa.harvard.edu.
