The Palomar Transient Factory is a synoptic sky survey being carried out on the 48-inch Oschin Schmidt Telescope at Palomar Observatory, which is the same telescope as used for the well-known POSS survey some fifty years earlier. The PTF camera was formerly the CFHT-12k camera and has been substantially modified for its new mission, most notably through the use of a mechanical cryo-cooler instead of liquid nitrogen, a new image flattener, and electronics modifications. The camera has 11 functional 2048x4096 CCDs, with a roughly 1 arcsecond per pixel plate scale, yielding a total area per exposure of just over 7 square degrees. A shutter provides accurate exposure timing. A filter exchanger mechanism allows up to two filters to be used. Typically, these are R and g-band; an additional set of H-alpha filters are also in use. The camera saw first light on December 13, 2008 and has been in routine operations since mid-2009.
I am heading the development effort at IPAC. IPAC performs high-fidelity reduction and calibration of the data, and maintains a repository for all image and catalog data. Typical turnaround times for IPAC processing are of order 2-3 days before they appear in this archive, which is currently proprietary and for team-use only. We are also developing an NEO (near earth object) program.

Current sky coverage of PTF at R-band, as of July 8th, 2011. Most of the sky visible from the southern hemisphere and above the galactic plane has been sighted dozens of times.
