Further unfiltered CSS magnitudes for 2010lx: 2009 Nov. 17.33 UT, [20.4; 2010
Nov. 17.29, 18.4; Dec. 1.32, 18.5; Dec. 14.30, 18.5; 2011 Jan. 14.20, 18.7.
Further unfiltered CSS magnitudes for 2010ly: 2010 Nov. 3.26, [20.5; Dec.
14.18, 17.9. Further unfiltered CSS magnitudes for 2010lz: 2010 Nov. 13.24,
[20.4; Dec. 5.21, 18.7. Further unfiltered CSS magnitudes for 2011R:
2010 Dec. 13.48, [19.7; 2011 Jan. 29.40, 18.9. Further unfiltered CSS
magnitudes for 2011S: 2010 Apr. 13.16, 19.3; Dec. 5.46, 17.3. Further
unfiltered MLS magnitudes for 2011P: 2010 Sept. 18.40, [21.5; Dec.
14.09, 21.0. Further unfiltered CSS magnitudes for 2011Q: 2010 Nov. 12.44,
[20.5; Dec. 10.43, 20.4; 2011 Jan. 28.32, 19.9.
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.
