SUPERNOVAE 2006ic-2006ir
     The "Nearby Supernova Factory" collaboration (E. Pecontal and G.
Rigaudier, Centre de Recherche Astronomique de Lyon; P. Antilogus, S.
Gilles, R. Pain, and R. Pereira, Laboratoire de Physique Nucleaire et de
Haute Energies de Paris; C. Buton, Y. Copin, E. Gangler, and G. Smadja,

Laboratory, Berkeley; R. Kessler, Kavli Institute for Cosmological Physics,

University) reports the discovery of 16 supernovae in images obtained
during the month of September, using the QUEST II camera on the Palomar
Oschin 1.2-m Schmidt telescope.  Images obtained prior to Sept. 20 were
acquired in point-and-track mode as a part of the NEAT component (cf. CBET
263) of the Palomar-QUEST Consortium; images obtained after this date were
acquired in drift-scan mode, in conjunction with the Palomar-QUEST
Consortium.  A subsequent spectrum of each target (range 320-1000 nm),
obtained with the Supernova Integral Field Spectrograph on the University
of Hawaii 2.2-m telescope, was used for classification.  The letter
following the discovery magnitude in the table below specifies the band.
