SUPERNOVA 1999ac IN NGC 6063
M. Modjaz, J. Y. King, M. Papenkova, A. Friedman, R. A.Johnson,
W. D. Li, R. R. Treffers, and A. V. Filippenko, University of
California at Berkeley, report their discovery of an apparent
supernova in NGC 6063 during the course of the Lick Observatory
Supernova Search with the 0.8-m Katzman Automatic Imaging Telescope
(KAIT).  SN 1999ac was discovered and confirmed on unfiltered
observations taken on Feb. 26.5 (mag about 15.2) and 27.5 UT (mag
about 15.0).  The new object is located at R.A. = 16h07m15s.01,
Decl. = +7o58'20".4 (equinox 2000.0), which is about 23".9 east and
29".8 south of the nucleus of NGC 6063.  KAIT images of the same
field on 1999 Feb. 20.5 (limiting mag about 17.5) and 1998 July
21.2 (limiting mag about 19.0) show nothing at the position of the
supernova.

SUPERNOVAE
A. Kim, College de France, and N. Regnault, Laboratoire de
l'Accelerateur Lineaire, Universite de Paris-Sud, on behalf of the
EROS collaboration; and P. Nugent, Lawrence Berkeley National
Laboratory (LBNL), on behalf of the Supernova Cosmology Project,
report the discovery of nine supernovae, discovered in the course
of the automated supernova search with the 1-m Marly telescope (+
CCD) at La Silla (limiting mag about 21.5).  Finding charts can be
found at http://www.lal.in2p3.fr/EROS/SNe/Charts/.

SN 1999ad was confirmed on CCD frames taken on Feb. 12 but was not
present on a frame taken on Jan. 13; SN 1999aj was confirmed on CCD
frames taken on Feb. 18 but was not present on a frame taken on
Jan. 22.  SN 1999ae was confirmed with a CCD spectrum taken at the
APO 3.5-m telescope by X. Fan (Princeton) and H. Newberg (Fermi
National Accelerator Laboratory) on Feb. 17; Nugent, G. Aldering,
and S. Deustua (LBNL) note that the spectrum is consistent with a
type-II supernova, < 1 month old; z = 0.076.  SN 1999af was
confirmed with a CCD spectrum taken at the Lick 3.0-m telescope by
Aldering on Feb. 25; Nugent and Deustua find that the spectrum is
consistent with a type-Ia event, 1 week after peak brightness; z =
0.097.  A. Goobar (Stockholm University) and I. Hook (Royal
Observatory, Edinburgh) obtained a CCD spectrum of SN 1999ag on
Feb. 13 at the Nordic Optical Telescope (NOT); they, along with
Nugent and Aldering, find that the host galaxy has z = 0.0988 from
O III, H-alpha, and H-beta lines.  The spectrum of SN 1999ag is
most consistent with an early type-II supernova at the same
redshift; however, the spectrum's signal-to-noise is too poor to
state this with much confidence.
