        OSIRIS-LGS (see OSIRIS note below)
        MOSFIRE

Keck 2 Instruments are:


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

Subaru Time Exchange Instruments are:

Suprime-Cam (limited), FOCAS, HDS, MOIRCS (limited), IRCS (with NGS/LGSAO with 188 elements), FMOS, COMICS, and Hyper Suprime-Cam (limited, shared risk). See below for limitations.
       

Telescope Limits

Please note that Keck I and Keck II have different eastern and western telescope limits. This affects the times objects will be available for observing. Objects can be acquired earlier on Keck II and followed later on Keck I.

Special Notes for Semester 2016A:

Visitor Instruments: WMKO will not support any visitor instruments during semester 2016A.

Keck II Laser: In order to support the installation and testing of the new Keck II laser, the Keck II LGS AO system will be unavailable for science through mid-April 2016. The Keck II NGS AO system will be available for science throughout semester 2016A. The Keck II LGS AO system will be available for shared-risk science from mid-April 2016 onward.

OSIRIS will be unavailable for science through early March 2016 for the spec detector upgrade.

NIRSPEC (NIRSPAO) will be unavailable for four weeks in March 2016 in order to conduct a routine servicing mission to remove ice from the dewar window.

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. Subaru time may be traded for time on both Keck telescopes, the exact number of nights depending both on the Keck and the Subaru demand. Neither Keck nor Subaru will support Target of Opportunity (ToO) observations during the exchanged nights. All observations will be executed in the "classical" observing mode. During semester 2016A Hyper Suprime-Cam is being offered to the Keck community for a maximum of three nights in a shared-risk mode. Hyper Suprime-Cam will be available on dark and gray nights in February, March, April, June and July 2016. S-Cam will only be available on dark and gray nights in May 2016.

LGS-AO: A detailed set of guidelines for LGS-AO nights and information on the capabilities of the systems may be found on the 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 or NGS programs or HIRES on Keck I.

NIRSPAO is scheduled in campaign mode given limited demand for this configuration. If there are insufficient requests for its use, NIRSPAO may not be scheduled in a given semester.

KOA (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. Please see the KOA homepage for information on the archive. Please also see the KOA proprietary period policy.
