We are building the setiQuest open community to involve the world in five different threads of a SETI program on the ATA. setiObs are the routine observations at the ATA, that will be the beneficiary of the other four setiQuest threads, with the resultant improvement in search speed and expansion of the classes of signals that can be detected during targeted star searches and surveys. setiCode involves publishing and improving our current SonATA code base as an open source project. setiData is a weekly program to capture, and make available through Amazon Web Services, several hours of raw data recorded from the output of one of the beamformers at the ATA. These data can be used by the community for analyses and testing of new signal processing algorithms for complex, noise-like signals with a large number of degrees of freedom, or improved algorithms for the types of narrowband, continuous or pulsed signals already identified by SonATA. setiCloud is a stack built by Cloudant, Inc. that allows access to computational and storage resources available in the Amazon Cloud for setiQuest use. setiCitizen is our attempt to use the pattern recognition capabilities of the human brain coupled with visual (and perhaps auditory) sensors to quickly find signals in noise. The intent of this citizen science project is to allow crowdsourcing signal detection in certain portions of the terrestrial microwave window that contain so many signals that SonATA cannot now complete its detection and classification tasks within the required near-real-time constraint. Patterns indicating signals that have been validated and screened against known interference will be scheduled for automatic follow up observations. The setiQuest community is being encouraged to help with the development of the tools needed for these five threads as well as utilizing the end products.
