SUPERNOVAE 2006sa-2006sq
     B. Leibundgut, European Southern Observatory (ESO); J. Sollerman,
DARK Cosmology Center; R. Foley, University of California, Berkeley; S.
Rodney, University of Hawaii; P. Challis, Harvard-Smithsonian Center for
Astrophysics; and K. Boutsia, ESO, on behalf of the ESSENCE project (cf.
CBET 717; IAUC 8427, 8464), report the discovery of 17 supernovae on
multiple R- and I-band images taken at the Blanco 4-m telescope (equipped
with the MOSAIC II camera) during Nov. 10-29 by project members.
Spectroscopic observations (range 380-890 nm) were obtained with Keck I
(+ LRIS), Keck II (+ DEIMOS), the Very Large Telescope (+ FORS1), and the
Magellan Baade Telescope (+ IMACS).  The table below includes the R-band
discovery magnitude, the redshift (z), the spectroscopic type, and an
estimate of the phase (age, in days from maximum brightness; general
uncertainty +/- 2 days) for each object.
