We used the Harvard University 16-inch Clay Telescope on 2011 February 22 and March 1 to observe the nearby Type IIn SN 2010jl (CBET #2532, CBET #2536) and Type Ia SN 2011B (CBET #2625) in the V-band. Both SNe are clearly detected in our images and we report median combined magnitudes of V=14.4 +- 0.2 mag and V=14.8 +- 0.2 mag for SNe 2010jl and 2011B, respectively.
Adopting a distance modulus of (m-M)~33.45 mag for UGC 5189, the host galaxy of SN 2010jl, we estimate that the absolute magnitude of the SN is V ~ -19.0 at roughly 4 months after initial discovery (Stoll et al., ApJ, 730, 31 (2011)). In comparison to the absolute magnitude light-curve of the Type IIn SN 2006gy (Smith et al., ApJ, 666, 1116 (2007)) at a comparable epoch, SN 2010jl is roughly a magnitude fainter.
We thank Allyson Bieryla for assistance with these observations.
