The supernovae were spectroscopically confirmed on Nov. 29, Dec. 3, and Dec. 4 using the Palomar 5-m telescope (+ DBSP). Classification was carried out using the SNID cross-correlation program (Blondin and Tonry 2007, Ap.J. 666, 1024). In addition to the results above, 2010kl (cf. CBET 2567) is found to be a normal type-Ia supernova. Further CSS magnitudes for 2010ky: 2009 Dec. 16.12 UT, [20.2; 2010 Sept. 10.39, 19.2; Oct. 7.27, 19.3; Nov. 8.21, 19.4; Dec. 6.18, 20.0.
