Gemini Fast Turnaround: June 2023

June 26, 2023

We are pleased to announce the monthly Call for Proposals for the Gemini Fast Turnaround (FT) Program. The upcoming deadline is 12:00 (noon) Hawai‘i Standard Time on 30 June 2023. Proposals are being accepted for both Gemini North and South. For successful proposals this cycle, observations will be active in the queue August–October 2023. 

For Gemini South, GMOS-S and F2 (including F2 MOS mode) are available this cycle, although it is expected that GMOS-S will not be available for a period in August. Both IGRINS and Zorro will be available for at least part of the cycle. For Gemini North, most instruments will be available for at least a portion of the cycle. Make sure to check the 23B instrument schedules for detailed availability, or check with the FT team at Please see the Call for Proposals for more information.

Additionally, please be aware that we are offering FT time for Gemini South for only the first 3 monthly cycles of 23B. This call is for the first cycle. The available time for the latter three cycles at Gemini South will be devoted to a special shared risk GHOST call, expected to be announced on September 1. 

The FT program has been used to conduct pilot studies, complete observations for existing data sets, follow up newly discovered objects, and much more. Proposers will have two weeks to peer review up to eight other proposals. Results will be announced around the 21st of the month following the deadline. Data for successful programs can be obtained as early as one to two weeks after that. The FT program uses a dual anonymous review process (DARP). Proposals must use the FT DARP proposal templates and be anonymized as described in the Call for Proposals
