SUPERNOVAE 2006ny AND 2006qs-2006ry
     The Nearby Supernova Factory (E. Pecontal and G. Rigaudier, Centre de
Recherche Astronomique de Lyon; P. Antilogus, S. Gilles, R. Pain, and R.

the discovery of 33 supernovae in images obtained during the months of
October and November, using the QUEST-II camera on the Palomar Oschin 1.2-m
Schmidt telescope.  Those supernovae discovered on Oct. 26 October and Nov.
1 were found in SDSS i-band or r-band images taken in drift-scan mode as a
part of the QUEST component of the Palomar-QUEST Consortium; the other
supernovae were discovered in point-and-track mode as a part of the NEAT
component (cf. CBET 263) of the same Consortium.  Subsequent spectra (range
320-1000 nm) of each target, obtained with the SuperNova Integral Field
Spectrograph on the University of Hawaii 2.2-m telescope, were used for
classification of supernova types (as listed in the table below).
Those type-Ia supernovae with z < 0.08 were all discovered at or after
maximum; the supernovae with z > 0.08 include some that were discovered
before maximum.  The final column below gives the estimated time in weeks
before (-) or after (+) maximum light for the type-Ia supernovae at the
discovery date, based on the spectra; an "M" indicates that the object was
within a few days of maximum at discovery; the three objects labelled "P"
in this column had inadequate S/N to get a satisfactory phase, but they
were clearly post-maximum.  All magnitudes listed below are calibrated to
the R band.

SN 2006rk appears to be associated with the galaxy MCG +05-17-19.
SN 2006rs appears to be associated with IC 28.
     Also, SN 2006ny (cf. CBET 743) was found independently at mag
19.83 on QUEST images taken on Nov. 14.2 UT (type II; z = 0.07;
R.A. = 0h39m17s.26, Decl. = +0d05'02".9, equinox 2000.0).
