The Keck Observatory Titan Monitoring Project is a collaboration between
observatory staff and visiting astronomers, intended to further our
understanding of Titan's surface and atmosphere by acquiring frequent,
high-resolution snapshots Titan using the Keck 2 adaptive optics system.
This project began in September 2003 and continued until shortly after
the landing of the Huygens spacecraft on Titan in January 2005.
In addition to the Keck Titan Monitoring Project images, marked as
belonging to Team Keck in the table below, other interested observers
have contributed images of Titan taken during this period to this web page.
However, these are not available for download.
