You are here

The Fast Turnaround (FT) observing mode allows the user the possibility of converting an idea into data much more quickly than the regular semester process (monthly proposal submission and assessment, with data obtained for accepted proposals 1-4 months after the submission deadline).

FT proposals do NOT need to be urgent to qualify; they just need to be good. Consider using FT rather than the regular semester process for:

  • short, self-contained projects that will result in publications
  • pilot/feasibility studies,
  • following up unusual/unexpected astronomical events,
  • speculative/high risk - high reward observations of fairly short duration,
  • completion of a thesis project, when only a few short observations are needed, and
  • completion of an existing data set to allow publication, when only a few short observations are needed.
  • However, users may propose for any kind of project that they believe is suited to the program.

    The FT program is run by a team of Gemini staff scientists and relies on the existing Phase I and Phase II tools, automated interactions between the proposers and Gemini, and rapid review of proposals by PIs or co-Is of other proposals submitted during the same round.

    Approximately 10% of the time at both Gemini North and South is currently available for the program. PIs affiliated with the participating partners (rule #4) may submit FT proposals, but the total FT time per partner may not exceed that partner's 10% limit per semester (rule #4).

    The total amount of time awarded each month to FT programs will not exceed 20 hours per telescope.

    The Fast Turnaround pages are organized as follows.

  • Current call for proposals
  • Overview of the FT Program: a basic description of the process
  • The rules of the FT program: should be read by anyone submitting a proposal
  • Questions and answers, giving more in-depth explanations of various aspects of the program
  • For available instruments please see under instruments
  • News about the program, e.g. oversubscription factors, observing reports.
