April 29, 2025: Cycle 4 Proposal Call Announcement
The DKIST Cycle 4 Proposal Call opened on April 29, 2025.
Proposal Submission Deadline: May 29, 2025 (23:00 GMT)
The National Science Foundation’s (NSF) Daniel K. Inouye Solar Telescope (DKIST) is pleased to solicit Proposals Cycle 4 observations.
The Cycle 4 observations will most likely take place during an approximately 9-month window between March and November 2026. During this window, the available on-sun time (i.e., the time available for observations) will continue to be limited and balanced against technical project needs.
Proposers are asked to carefully read and use the full description of the DKIST Cycle 4 Call for Proposals for the planning and preparation of their Proposals.
Any dates may still change. Updates will be provided.
