Title: Progress and Prospects at the W.M. Keck Observatory Taft Armandroff Keck Observatory Abstract: Taft Armandroff started as Director of the W.M. Keck Observatory on July 1, 2006. His talk will include recent progress at Keck Observatory on new instruments, telescope and instrument upgrades, and plans for the future. A number of instrumental enhancements are underway, including a detector upgrade for the red arm of LRIS, the new multi-object infrared spectrograph MOSFIRE, and the cross-dispersed infrared spectrograph NIRES. Adaptive optics enhancements that will be discussed include enabling laser-guide-star adaptive optics on the Keck I telescope, in addition to the existing system on Keck II, and the design of a next-generation adaptive optics system and related instrumentation. Statistics on the scientific output of Keck Observatory will also be featured
