Observing time on the Keck Observatory 10-meter telescopes is available to members of several communities: the University of California, Caltech, NASA, the University of Hawaiʻi, Notre Dame University, and NOIRLab. Swinburne University of Technology, Yale University, and Northwestern University access telescope time through Caltech. The Subaru Telescope community accesses Keck Observatory through an observatory exchange.
Each community has its own Time Allocation Committee (TAC) that reviews proposals semi-annually and assigns time based on the scientific merit of each proposal. Those time assignments are then used to generate the night-by-night schedule for each of the telescopes.
Keck Science Meeting
This year’s annual Keck Science Meeting will be held September 15-16 as a hybrid event. You may attend in-person at Caltech or virtually via Zoom and Slack. Learn more about the exciting science results made possible by Keck Observatory’s science community and register today!
