The Palomar Transient Factory (PTF) is a fully-automated, wide-field survey aimed at a systematic exploration of the optical transient sky. The survey is performed using a 7.26 square degree camera installed on the 48 inch Samuel Oschin telescope at Palomar Observatory; colors and light curves for detected transients are obtained with the automated Palomar 60 inch telescope. In the standard 60 s exposures the survey reaches a depth of R=20.6 (5-sigma, median seeing). Each PTF field contains tens of thousands of stars, including several thousand M-dwarfs. As of the beginning of 2011 the PTF survey has collected more than 25 epochs on over 6000 square degrees of the sky, and more than 100 epochs on 750 square degrees. Few-millimag long-term photometric precisions are achieved on the brighter targets. Ongoing PTF stellar science programs include a search for transiting planets around 100,000 M-dwarfs, a rotation and activity study in open clusters, the monitoring for outbursts and a search for transiting planets in young stellar regions, galactic structure measurements, and a variety of other stellar variability programs.
