2025B Call for Proposals

The 2025B Gemini Observatory Call for Proposals has been released. Proposals are being accepted for observations between 1 August 2025 and 31 January 2026. Gemini North and Gemini South are expected to have 128 and 159 nights available for science, respectively. A new version of the Phase I Tool (PIT) has been released to support proposal submissions. All Gemini proposals requesting time from the U.S., Canada, Brazil, or Argentina must be anonymized. This applies to programs requesting time only from each of those partners, as well as joint programs requesting time from multiple participants which include them. All proposals to use Gemini in 2025B must use the 2025B PIT template. The submission deadline ranges from 31 March to 3 April 2025, depending on the partner country/institution.
