SUPERNOVAE 2002iu-2002je
     R. C. Smith and N. Suntzeff, Cerro Tololo Interamerican
Observatory (CTIO); and C. Stubbs, University of Washington, on
behalf of the ESSENCE project (involving also C. Aguilera, B.
Barris, A. Becker, P. Challis, R. Chornock, A. Clocchiatti, R.
Covarrubias, A. V. Filippenko, P. Garnavich, S. T. Holland, S. Jha,
R. Kirshner, K. Krisciunas, B. Leibundgut, W. Li, T. Matheson, A.
Miceli, G. Miknaitis, A. Rest, A. Riess, B. Schmidt, J. Sollerman,
J. Spyromilio, and J. Tonry), report the discovery of ten
supernovae, each present in at least two bands (V, R, I) taken with
the CTIO Blanco 4-m telescope (+ 8K Mosaic II imager) by project
members and S. Nikolaev.  The supernovae were identified via
subtraction of images taken on Oct. 8-14 UT (when none of the new
objects was visible, to limiting mag R about 23.5) from those taken
on the tabulated discovery dates, with further confirming images
taken on Nov. 11 and 13, and with spectroscopy obtained on Nov.
1-11 by project members at the Keck I (+ LRIS), Keck II (+ ESI),
and MMT telescopes and by M. Hamuy at the Magellan telescope.  SNe
2002iu (z = 0.1), 2002iv (0.2), 2002iy (0.5), 2002iz (0.4), 2002ja
(0.3), 2002jb (0.2), 2002jc (0.5), and 2002jd (0.3) are of type Ia;
SNe 2002iw (z = 0.2) and 2002ix (0.3) are of type II.  Offsets are
from the host-galaxy nuclei; in some cases no host was detected.
Additional supernova suspects, finding charts, and FITS images are
available at http://www.ctio.noao.edu/essence.
     Further to IAUC 8017, B. Beutler and W. Li report the KAIT
discovery of SN 2002je.  Additional unfiltered magnitudes:  Oct.
31.2, [19.0: (KAIT); Nov. 21.1, about 17.5 (M. Schwartz, 0.8-m
Tenagra II automated telescope).
