We present the latest results from the first two of our Nearby Galaxies Supernova Search (NGSS) campaigns. These campaigns were conducted at KPNO 0.9m using the 8K x 8K MOSAIC camera. The wide-field provided by this camera (59' x 59') allowed us to search over 450 square degrees of sky along the celestial equator for SNe, to a limiting magnitude of R 21. Using search algorithms similar to those used by High-z Supernova Search Team for their campaigns, we have collected a sample of 15 SNe of various types and ages. With facilities at CTIO, we have photometrically followed many of these SNe and obtained very well sampled light curves. We present a detailed description of our search techniques, and preliminary light curves of several of our SNe. We plan to conduct one to two more of these campaigns at the KPNO 0.9m, thus ultimately collecting a sample of 25 nearby SNe for follow-up and statistical analysis.
