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.

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.
