The Moving Object and Transient Event Search System (MOTESS) has been operating for the past year as a prototype for the Global Network of Astronomical Telescopes (GNAT). During this time, it has produced approximately 200 nights of observations on a 48-arcminute band of declination near the celestial equator. We have developed an automated data reduction pipeline that performs aperture photometry and differential photometry on the nightly data and then matches the results to a standard catalog based on the United States Naval Observatory catalog. Objects that match the catalog are added to the data library, while unmatched objects are placed into a separate catalog for analysis. One data analysis technique we have been exploring is to search the new object catalog for transient events such as supernovae and cataclysmic variables. We have also been optimizing the pipeline so that it can be scaled as additional instruments are added to the GNAT network.
