On October 11, 2007, the 42-element Allen Telescope Array was dedicated at Hat Creek in California, and is now undertaking routine science operations. With its wide field of view (about 5 square degrees at 1.4 GHz), the ATA is one of the most powerful radio survey telescopes in the world.
We describe initial results from ATA observations of a 100 square degree field centered on the NOAO Deep Wide Field Survey, and plans for the first year of operation, including the Five GHz Sky Survey (FiGSS), which will reach a detection threshold of 3 mJy over 10,000 square degrees, and greater depth in two smaller fields. FiGGS will be the highest frequency deep, large radio survey in existence, and will also be useful for transient detection and Galactic science.
Plans call for additional ATA antennas to be added in stages (for a total of 350) providing increased angular resolution and sensitivity. Our observing methods and results lay the groundwork for the Square Kilometer Array.
