SUPERNOVAE 2006lw-2006mn
     G. Pignata, Pontificia Universidad Catolica de Chile; P. Challis and
W. M. Wood-Vasey, Harvard-Smithsonian Center for Astrophysics; and T. Davis,
Dark Cosmology Center, Niels Bohr Institute, University of Copenhagen; on
behalf of the ESSENCE project (cf. IAUC 8427, 8464), report the discovery of
18 supernovae on multiple R- and I-band images taken at the Blanco 4-m
telescope equipped with the MOSAIC II camera during Sept. 13-27 and Oct.
10-24 by project members.  Spectroscopy observations (range 380-890 nm) were
obtained on Oct. 22-24 with the Very Large Telescope (+ FORS1) and the
Magellan Clay telescope (+ LDSS3), showing each to be type-Ia supernovae
except for 2006lz, which is of type II.  The column labelled "Offset" gives
the distance of the supernova from the apparent host galaxy's center in
arcseconds.
