The Carnegie Supernova Project (CSP) was a five-year observational survey conducted at Las Campanas Observatory that obtained, among other things, high-quality light curves of 100 low-redshift Type Ia supernovae (SNeIa). Presented here is the second data release of nearby SNIa photometry consisting of 50 objects, with a subset of 45 having near-infrared follow-up observations. Thirty-three objects have optical pre-maximum coverage with a subset of 15 beginning at least five days before maximum light. In the near-infrared, 27 objects have coverage beginning before the epoch of B-band maximum, with a subset of 13 beginning at least five days before maximum. In addition, we present results of a photometric calibration program to measure the CSP optical (uBgVri) bandpasses with an accuracy of 1%. Finally, we report the discovery of a second SNIa, SN2006ot, similar in its characteristics to the peculiar SN2006bt. © 2011. The American Astronomical Society. All rights reserved.
