Important dates

• Proposal deadline: 23:59, Hawaiian Standard Time (HST), April 30
• Please ensure the latest version of the 19B PIT is used for submission.
• Reviews must be completed by 23:59 HST, May 14. If you have submitted a proposal, but by the 2nd of the month have not received an email from FT regarding reviewing proposals, contact FT as soon as possible.
• Results will be announced by May 21
• The deadline for preparing observations (Phase II) is May 31. Accepted programs meeting this deadline will be active from 1 June 2019 until 31 August 2019
• FT observations will be merged with the queue and observed on queue nights.

Eligibility

• PIs from all participant countries taking part in the FT program may apply for this cycle.
• We further welcome Japanese community PI proposals.
• PIs from participant countries whose FT time for the semester has been used up should not apply for the remainder of the semester. Note that some participant countries only have very small amounts of FT time available each semester. Currently no partners have reached their limit.  See Rule #4 and Q&A for more information.

Acceptable RA ranges

• Gemini North: Targets from about RA = 10.5 hrs to 3.5 hr are acceptable during this cycle. Also note that RAs near 10.5 hrs will only be accessible for a couple hours during the first half of the first month (June) and only at northern declinations ( Dec> 0). Likewise, RAs near 3.5 hr will only be accessible for a few hours during the final month (August) and again only in the above declination range. Note Rule #9; an FT program may not fully backload its three-month active period; at least one of its targets must be observable during its first active month.
• Gemini South: Targets from about RA = 9.5 hr to 3.5 hrs are acceptable during this cycle. Note, however, that RAs near 9.5 will only be accessible for a few hours during the first half of the first month (June) and only at favorable declinations (Dec < 0) . Likewise, RAs near 3.5 will only be accessible for a few hours during the second half of the final month (August) and again only in the above declination range. Note Rule #9; an FT program may not fully backload its three-month active period; at least one of its targets must be observable during its first active month.

Available instruments and observing modes:

Gemini North

• Please see the telescope schedule for detailed instrument availabilities.
• Please note that Gemini North is closed for annual maintenance starting July 22 - Aug 25.
• There is one GRACES run during this cycle (June 20-27).
• NIFS is not offered during this cycle as it is currently not scheduled to be on the telescope during this period.
• LGS is offered with NIRI and GNIRS this cycle. 

Gemini South

• See the telescope schedule for detailed instrument availabilities.
• Please note that Gemini South is closed for annual maintenance during August 12-26. 
• From June 10 to June 25 GMOS South will not be available
• GMOS-S and Flamingos-2 are otherwise expected to be available during this FT block.
• A limited amount of GPI time may be available intermittently through the 3-month FT block. Contact the FT team for details.
• GeMS+GSAOI, and PHOENIX are currently not available for FT.

Both telescopes

• FT observations may not be executed during classical observing and priority visitor (PV)  blocks, depending on the prevailing conditions.
• For visiting instruments not listed above, you must contact the FT team before submitting a proposal to check availability (Fast.Turnaround at gemini.edu)
• For GMOS proposals, please indicate in the Technical section if your program could be carried out with either GMOS (North or South).
• The R600 grating in each GMOS instrument is NOT offered for FT (or regular queue) observations.
• MOS observations are available for FT, subject to some caveats/restrictions
• As discussed in the rules and Q&A, please contact the Fast Turnaround team in advance of the deadline if you would like to propose for an unusual instrument configuration or observing mode.

Time available

• 20 hrs per month at each telescope is available for FT observations. Very roughly, this implies:
  • 4 hrs of 20%-ile conditions (IQ=20, for example; see this web page)
  • 10 hrs of 50%-ile conditions
  • 14 hrs of 70%-ile conditions
  • 17 hrs of 85%-ile conditions
• PIs may propose for up to the amount of time in their most restrictive observing conditions, subject to partner's time availability - see rule #4 . For example, a proposal requesting CC50 IQ20 SB50 WVany conditions can request no more than 4 hrs of observing time.

PIT information

• Proposals must be submitted using the version of the Phase I Tool specified on this web page (in the "Time Requests" tab, select Fast Turnaround Observing at Gemini as the proposal class).
• In the Time Requests tab, select "Fast Turnaround Observing at Gemini" as the proposal class and specify the reviewer (and mentor, if appropriate). Note that this is where the reviewer is defined; changes cannot be made after the proposal has been submitted.
• Dedicated LaTeX/Word templates must be used to prepare FT proposals: tex | sty | doc.
• Submitting the same proposal more than once during a given month (e.g. after correcting/editing a submitted version) should be avoided if at all possible. Only submit when you are sure your proposal is ready to be reviewed.
• The FT proposal template (which differs somewhat from the queue template) is now compulsory for all FT proposals.
