SUPERNOVAE 2006K, 2006L, 2006M

three supernovae in NEAT images obtained using the Palomar Oschin
1.2-m telescope (+ QUEST II camera).  Discovery-image dates and
approximate magnitudes (calibrated to R) are listed in the table below.
Spectroscopy (range 320-1000 nm) of these objects were obtained on
Jan. 18.5-18.6 UT with the University of Hawaii 2.2-m telescope (+
Supernova Integral Field Spectrograph); redshifts were derived from the
peak of the observed H_alpha emission:  2006K, z = 0.03; 2006L, 0.04;
2006M in PGC 47137, 0.015.  The host galaxy of 2006L, 2MASX
J13070825+2838003, has z = 0.03940 (measured by Wegner et al. 2003, A.J.
125, 2373; via NED); PGC 47137 has z = 0.01544 (measured by Rines et al.
2003, A.J. 126, 2152; via NED).
