Observing at WMKO

Applying for Keck Telescope Time

Each user community, University of California, Caltech, NASA, University of Hawaii, Subaru, Yale, Swinburne, Notre Dame, NOIRLab, and Northwestern has its own internal requirements regarding deadlines for submittal of proposals and information required to apply for time on the Keck telescopes. However, regardless of the institution to which the user applies, (s)he should complete the WMKO Proposal Cover Sheet Form and submit it, along with the individual institution request forms, to the appropriate TAC. This form is used, once a given proposal has been allotted time by its TAC, to concatenate the approved time assignments into the master schedule. Observers will be notified by the appropriate TAC of the fate of their proposal and by WMKO for telescope time assignments if the proposal was accepted. Telescope schedules will be posted on the W.M. Keck Observatory web pages approximately two months before the beginning of the semester.
