the Catalina Sky Survey (CSS) 1.5-m telescope.

 SN       2010 UT        R.A. (2000.0) Decl.      Mag.      Offset
 2010kl   Nov. 16.47   11 27 17.48  + 3 45 33.3   18.9    0".3 W, 10".0 N

SN 2010kl is not seen co-added Mt. Lemmon Survey (MLS) images reaching mag
22.5 or in Sloan Digital Sky Survey DR7 images reaching a similar depth; its
presumed host galaxy (CGCG 39-184) has redshift z = 0.035.  Further magnitudes
for 2010kl:  May 5.15 UT, [20.5 (MLS); Dec. 1.45, 19.2 (CSS).  SN 2010km is
not seen in MLS co-added images reaching mag 22.0; its presumed host galaxy
(CGCG 484-24) has redshift z = 0.023.  Further magnitudes for 2010km:  Nov.
17.19 [19.5 (CSS); Nov. 28.35, 19.2 (CSS); Dec. 5.31, 18.7 (MLS).
