SUPERNOVAE 1999as and 1999at IN ANONYMOUS GALAXIES
R. Knop, G. Aldering, S. Deustua, G. Goldhaber, M. Kim, and
P.Nugent, Lawrence Berkeley National Laboratory, on behalf of the
Supernova Cosmology Project (SCP), report the discovery of two
supernovae on Feb. 18 UT as part of a joint collaboration between
the SCP and E. Helin, S. Pravdo, D. Rabinowitz, and K. Lawrence
(Near-Earth Asteroid Tracking project, Jet Propulsion Laboratory):
SN 1999as is located at R.A. = 9h16m30s.86, Decl. =+13o39'02".2
(2000), on the edge of a very faint galaxy. Currently SN 1999as is
at V = 18.3.
SN 1999at (unfiltered mag 18.8) is located at
R.A. =10h23m11s.30, Decl. = +17o59'06".0 (2000). An R-band
image from the YALO 1-m telescope obtained Mar. 7 by D. G. Huerta
(CTIO), A. Mourao (Centro de Astrofisica, Instituto Superior
Tecnico, Lisbon), and Rui Agostinho, Joao Lin Yun, and F. D. Santos
(University of Lisbon), confirmed the presence of the supernova and
that the host was an elliptical galaxy.

SUPERNOVAE 1999au, 1999av, 1999aw, 1999ax, 1999ay
Five new supernova discoveries have been reported -- two by A.
Gal-Yam and D. Maoz (on behalf of the Wise Observatory Optical
Transients Search, at the Wise 1-m reflector; cf. IAUC 7055), and
three on Mar. 9 by L. G. Strolger and R. C. Smith (on behalf of the
Supernova Cosmology Project, at the Kitt Peak 0.9-m telescope; cf.
IAUC 7125, 7128).
