SUPERNOVAE 2000I AND 2000J
     A. V. Filippenko and A. L. Coil, University of California at
Berkeley, report that uncalibrated CCD spectra (range 330-1000 nm),
obtained on Mar. 15 UT with the Shane 3-m reflector at Lick
Observatory, reveal that SN 2000I (cf. IAUC 7362) is of type II.
Broad H-alpha emission and weak H-alpha absorption are visible.
The approximate recession velocity is 6400 km/s, based on narrow
emission lines in the host galaxy.  SN 2000J (ibid.) is also of
type II; the noisy spectrum, obtained under poor conditions, is
consistent with a recession velocity of nearly 12 000 km/s.


SUPERNOVA 2000P IN NGC 4965
     S. Jha, P. Challis, and R. Kirshner, Harvard-Smithsonian
Center for Astrophysics, report that further spectra of SN 2000P,
taken by P. Berlind on Mar. 14.4 and 15.4 UT, show that it is a
type-IIn supernova.  Spectra taken in good seeing show that the
observed narrow (FWHM < 500 km/s) H-alpha and H-beta emission (cf.
IAUC 7379) is intrinsic to the supernova.  The combination of the
narrow emission with broad absorption features of H-beta and He I
makes this spectrum unusual.  These spectra are posted on the World
Wide Web at
http://cfa-www.harvard.edu/cfa/oir/Research/supernova/RecentSN.html.


V4642 SAGITTARII = NOVA SAGITTARII 2000
     N. N. Samus, Sternberg Astronomical Institute, Moscow, on
behalf of IAU Commission 27, informs us that the designation V4642
Sgr has now been given to this nova (cf. IAUC 7362, 7363, etc.).
