Target of Opportunity (ToO) Policy



Caltech Optical Observatories supports a Target of Opportunity (ToO) program to enable its researchers to acquire data on unexpected, transient events by allowing interruption of regularly scheduled programs of Caltech observers at the Keck telescopes and the Palomar 200-inch telescope. In such cases, the observer at the telescope is obliged to set aside his or her program and make specific observations on behalf of the ToO researcher.

Details of the ToO Program:
