We present preliminary results of our October 2002 campaign at the KPNO 4m telescope as part of an ongoing search for transiting extrasolar planets. Our goal is to detect transiting planets and to derive statistics of planet frequency, radius, and mass for stars ranging from types early G to late K. Planet transits will be detected via 1% photometric precision lightcurves with 4 minute time sampling spanning 18 nights per run. Transit searches will mark a new era in planetary discovery and characterization. Planet radii, which provide constraints on composition, evolution, and migration history, can only be measured for transiting planets. In addition absolute planet mass can be determined with follow-up radial velocity measurements. Our lightcurve database will have unprecedented time sampling and very high photometric precision for hundreds of thousands of stars, enabling new research on variable and binary stars, short microlensing events, and moving objects such as asteroids.
