Click for the 2022B NASA Keck Call for Proposals

The call for proposals for NASA Keck time in observing semester 2022B (August 1, 2022-January 31, 2023) is now open for professional research using the NASA allocation for telescope observing time at the W.M. Keck Observatory.

The opportunity to propose as a Principal Investigator (PI) for the NASA time on the Keck Telescopes is open to all U.S.-based astronomers, i.e. those with their principal affiliation at a U.S. institution.

Key Dates

Thursday, March 3, 2022: Deadline to request the required letters of support from NASA HQ and the supported project for General Mission Support proposals.

Thursday, March 17, 2022 by 4 pm US PDT: All proposals and supporting letters due to NExScI by 4 pm US PDT

Application Procedure

Starting in 2022A, the NASA Keck TAC uses a Dual Anonymous Proposal Review (DAPR) process. Proposers prepare two documents: an anonymized Science Program and a non-anonymized Expertise and Access document.

Highlights for 2022B:

  1. Time Domain Astronomy and Target of Opportunity programs: Observers can propose for both Time Domain Astronomy (cadence) and Target of Opportunity (ToO) programs. See Section IV for important details on cadence requests as well as the number of ToO interrupts allowed each semester.
  2. Please note that due to ongoing AO upgrades, there may be times in the semester when AO is unavailable for cadence observations. Cadence program PIs are responsible for development of instrument scripts, providing documentation, and training of staff needed to make the cadence program a turnkey operation.

  3. Twilight Observing: Keck has a program for acquiring snapshot observations in morning twilight. The available instruments for twilight observing are OSIRIS-NGS (imager only) on Keck 1 and NIRC-NGS on Keck 2. The program is designed to accommodate extra infrared observations during normally scheduled visible observations, when those observations end early and surrender the last portion of the night. Each institution is limited to one (1) program per partner institution per semester. Programs designed for longer term (> 1-2 years) will be given priority. Click here for more information.
  4. At-Home ("pajama mode") Observing:

    As during the pandemic, Keck will continue support up to two observers for at-home observing: one primary and one secondary observer. Additional observers can join but cannot launch the VNC control system for the instruments. At-home observing requires the installation of software which only runs on Linux and macOS operating systems. At-home observers will be contacted by Keck staff and should work with this staff to install and test the software several days ahead of their run to allow time for troubleshooting.

    Pajama mode is available to first time observers although they are strongly encouraged to travel to Keck for their observations if possible.

  5. Semester Notes and Considerations for the Keck and Subaru instruments:
    • Keck I Telescope: There will be a 12-night period of shutdown and engineering occurring in either September or October bright time in order to conduct repair work on the Keck I telescope pier.
    • KCWI: KCWI will be unavailable during the 22B semester for the installation and commissioning of the red channel, KCRM.
    • NIRSPAO/NIRSPEC: Nirspec and Nirspao nights may be scheduled in campaign mode to limit the number of reconfigurations into AO during the semester.
    • NIRC2: The vortex coronagraph in LGS mode is not available. The vortex coronagraph with the PyWFS is only available through collaboration with the PyWFS and vortex development teams.
    • DEIMOS: The top-left CCD on the detector mosaic is noisier than the rest of the CCDs. Please see here for guidelines on how to design your MOS masks with this issue in mind.
    • Subaru Telescope Downtime: The Primary Mirror recoating and some maintenance work are planned from July 11 to September 30, 2022.
    • Other than this period of downtime, the Subaru-Keck exchange will continue as previous semesters with flexibility as to the number of nights available for exchange. Please see the available instruments page for complete information on Subaru.
