J. Marriner, D. McGinnis (Fermilab), G. Miknaitis, A. Becker, J. Frieman, J.
Holtzman, and A. Riess report confirming spectroscopy of 2007or, 2007ou, and
2007pg that was obtained with the ARC 3.5-m telescope on Nov. 4 UT.  R.
Romani, C. Zheng, M. Sako, C. Wheeler, D. Schneider, and R. Bender, together
with U. Hopp (University of Munich) and W. Kollatschny (University of
Goettingen), report confirming spectroscopy that was obtained with the
Hobby-Eberly Telescope on Nov. 4 and 5 for 2007oq, 2007os, 2007ov, 2007ow,
2007ox, 2007oy, 2007oz, 2007pe, 2007pi, and 2007pj.  A. Goobar, R. Nichol, M.
Molla (Centro de Investigaciones Energeticas, Medioambientales y
Tecnologicas, Madrid), F. Castander (Institut de Ciencies de l'Espai,
Barcelona), and R. Miquel (Institut de Fisica d'Altes Energies = IFAE,
Barcelona), report confirming spectroscopy that was taken by Miquel, Molla,
and L. Galbany (IFAE) at the 3.58-m Telescopio Nazionale Galileo on La Palma
on the nights of Nov. 4 and 5 for 2007ot, 2007pa, 2007pb, 2007pc, 2007pd,
2007pf, and 2007ph.  The discovery magnitudes tabulated below are all g
magnitudes; spectroscopic redshifts are given in the column labelled z.  Peak
dates (all 2007) are approximate estimates either from fits to the early
light curves or from the spectra, with a typical uncertainty of plus-or-minus
several days; in cases where such estimates are either uncertain or very
discrepant, they are not reported.  Types marked with a question mark (?)
imply that the type identification based on the spectrum is uncertain.
