Call for Keck Proposals


Second Semester 2014B (August 2014 through January 2015)

Proposals are due on March 14, 2014

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

5:00 P.M. on Friday, March 14, 2014.

Looking ahead: Proposals for First Semester 2015A (February 2015 - July 2015) will be due September 12, 2014.

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 roughly 63 UC nights total on Keck I and 56 nights on Keck II.

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

Instruments available on Keck 1 are:

  • HIRESb (blue x-disperser)
  • HIRESr (red x-disperser)
  • LRIS-ADC (red and blue, with ADC)
  • LRISp-ADC (polarimeter, with ADC)
  • OSIRIS-LGS (see LGS below)

Instruments available on Keck 2 are:

  • ESI
  • ESIi (ESI with the Integral Field Unit)
  • NIRSPEC (without AO)
  • NIRSPAO-NGS (NIRSPEC with Natural Guide Star AO)
  • NIRSPAO-LGS (NIRSPEC with Laser Guide Star AO; see LGS below)
  • NIRC2-LGS (see LGS below)

Particular notes for the 2014B semester follow:

Visitor Instruments: WMKO will not support any visitor instruments during semester 2014B.

NIRSPEC: NIRSPEC will undergo a "warm and pump" service mission in August 2014 and thus will be unavailable for that month.

DEIMOS: DEIMOS will undergo a service mission beginning in January 2015 and will be unavailable that month. It is likely the service mission will extend into the first weeks of February 2015 (semester 2015A)

Suprime-Cam (limited), FOCAS, HDS, MOIRCS (limited), IRCS (with NGS/LGSAO with 188 elements), FMOS, COMICS, and Hyper Suprime-Cam (limited) at Subaru: Through an exchange with the Subaru Observatory, several nights may be available to observers who would like to use any of these instruments. Please check the Subaru web site for detailed descriptions of these instruments and the Subaru Call for Proposals for instrument restrictions, particularly for S-Cam and MOIRCS. Neither Keck nor Subaru will support Target of Opportunity observations during the exchanged nights. All observations will be executed in the "classical" observing mode. During semester 2014B Hyper Suprime-Cam is being offered to the Keck community for a small number of nights (exact number to be determined in April) in a shared-risk mode.

LGS-AO: For semester 2014B there will be no restrictions on the number of LGS nights nor their distribution between telescopes. NIRC2, OSIRIS, and NIRSPAO with laser guide star adaptive optics will be available. A more detailed set of guidelines for these nights and information on the capabilities of the systems may be found on the Keck Observatory's LGS-AO page. Backup programs for LGS proposals are essential. Backup programs for LGS may be either NGS programs or non-AO (seeing limited) NIRSPEC on Keck II. Non-AO NIRSPEC is not available when NIRSPEC is in the AO configuration.

Keck Observatory Archive: Data from all instruments will be archived in the Keck Observatory Archive (KOA). The default proprietary period for all data is 18 months. If observers desire a different proprietary period they may request this through the Keck coversheet. The Keck Observatory's KOA homepage has information about the archive and the KOA proprietary period policy.

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.

The coversheet form is available through the Keck Observer Login webpage. Please attach your scientific justification.
