     Spectroscopic confirmation was taken with the Gemini North and South
telescopes (+ GMOS) between 2010 Dec. 15 and 2011 Jan. 25 UT.  Spectra were
identified using cross-correlation via a library of spectra using the SNIDS
program (Blondin and Tonry 2007, Ap.J. 666, 1024).  Measured redshifts:
2010lx, 0.10; 2010ly, 0.04; 2010lz, 0.09; 2011P, 0.08; 2011Q, 0.09; 2011R, 0.02;
2011S, 0.06.
