SUPERNOVAE 2000bl, 2000bm, 2000bn, 2000bo, 2000bp, 2000bq, 2000br
     L.-G. Strolger, University of Michigan and Cerro Tololo
Interamerican Observatory (CTIO); R. C. Smith and P. Candia, CTIO;
A. Soderberg, Bates College; P. Challis, Harvard-Smithsonian Center
for Astrophysics; and the rest of the Nearby Galaxies Supernova
Search Team report the discovery of seven new supernovae in their
recent search campaign conducted Mar. 21-31 using the Kitt Peak
0.9-m telescope (+ Mosaic camera).  The search is conducted to
limiting mag R about 21 in about 250 1-deg-square fields along the
celestial equator.  Search epoch frames are compared to template
frames obtained from two weeks to a year previously.

R. Corvarrubias (CTIO) obtained confirming CCD images of SNe
2000bm, 2000bq, and 2000br on Mar. 29 using the CTIO 0.9-m
telescope.  J. Krick and A. Athey (University of Michigan) obtained
confirming CCD images of SNe 2000bn and 2000bp on Apr. 1, and of
SNe 2000bl and 2000bo on Apr. 2, using the Hiltner 2.4-m telescope
at MDM Observatory.  SN 2000bq has no visible host galaxy.  SN
2000bn is at the host galaxy's center.  M. M. Phillips (Las
Campanas Observatory) identifies SN 2000bn as a type-Ia supernova,
at or before maximum light, from spectra (range 400-800 nm)
obtained by Strolger and Smith at the Mayall 4-m telescope (+ R-C
Spectrograph) on the nights of Apr. 2-4.  From spectra obtained on
the same evenings by Strolger and Smith, Phillips identifies SN
2000bp as a young type-II supernova with a redshift of about 0.06.
SN 2000br is identified as a type-II supernova from spectra
obtained at the Mayall 4-m telescope by R. Knopp and A. Conely
(Lawrence Berkeley Laboratories) on Apr. 1.83 UT and by Strolger
and Smith on Apr. 2-4.
