Call for Keck Proposals


First Semester 2016A (February 1, 2016 through July 31, 2016)

Proposals are due by 5pm PDT on Friday September 11, 2015

Please see for instructions on using the on-line process. The application process will end promptly at

5:00 P.M. on Friday, September 11, 2015

Looking ahead: Proposals for First Semester 2016B (Aug. 1, 2016 - Jan. 31, 2016) will be due March 11, 2016.

Keck is continuing the login-password system to allow you to retrieve and modify your coversheets. Returning observers should use the same account information as last semester. New observers may request an account from the login page.

We expect to allocate roughly 59 UC nights total on Keck I and 51 UC nights on Keck II.

Please see the Instruments Available web page for detailed notes on the current instruments.

Please read this paragraph: The principal consideration in evaluating proposals will be the scientific merit of the proposed project. Projects which take maximum advantage of the unique capability of the Keck Telescopes will be given high weight. A brief description should be given of backup programs that will be carried out if conditions are not suitable for the primary program.

Cover Sheets can be submitted through the Keck Observer Login webpage.
Proposals can be submitted through the UC Keck Proposal Handling System.
More details are in Instructions for Submitting Keck Proposals.

UCO Interim Director
