SUPERNOVAE
     P. Garnavich and P. Challis, Harvard-Smithsonian Center for
Astrophysics, on behalf of the High-Z Supernova Search Team, report
the discovery of seven supernovae on CCD images taken at the Victor
Blanco 4-m telescope at Cerro Tololo.  Each supernova is within
about 1" of its host galaxy's nucleus.  Spectra were obtained by B.
Leibundgut on Feb. 22 and 23 using the 3.6-m European Southern
Observatory telescope.  Following are given for each supernova the
dates of their discovery frames, position, R magnitude, redshift,
supernova type, and observing group (1 = N. Suntzeff, A.
Clocchiatti, and B. Schmidt; 2 = 1 + E. Turner and A. Athey):

Narrow emission lines from the host galaxies appear in the spectra
of supernovae 1996E, 1996F, 1996G, and 1996H.  Redshifts for the
other supernovae are based on correlating broad features with
spectra of nearby type-Ia supernovae.  Supernovae 1996F and 1996G
each show a featureless blue continuum.  Finder charts may be
requested by sending electronic mail to pgarnavich@cfa.harvard.edu.


COMET C/1996 B2 (HYAKUTAKE)
     R. M. West, European Southern Observatory (ESO), writes:  "Two
spectra (400-800 nm; resolution 1.2 nm; exposures 10 min each) were
obtained by K. Simon and C. Lidman (ESO) with the Danish 1.54-m
telescope (+ DFOSC) on Feb. 29.3 UT and reduced by S. Benetti (ESO).
The spectrum is typical for a comet at r = 1.5 AU.  The strongest
features are the Swan C2 (0,0) 516-nm, (1,0) 474-nm, and (0,1) 564-
nm bands.  Others identified are the C3 complex at 405 nm; CN (0,1)
at 422 nm; [O I] at 630 and 636 nm; NH2 (10,0), (9,0), (8,0), and
(7,0) at 570-662 nm.  With the possible exception of CO**+ at 427 nm,
no ionic lines are present in these spectra."
