ALMA Cycle 12 is currently scheduled for observations from October 2025 to September 2026. Users of any nationality or affiliation are invited to submit proposals before the deadline of 15:00 UT on Thursday 24 April 2025.

Observations that are strongly encouraged include:

  • ACA, especially in the LST range of 20h to 1h (note that ACA stand-alone proposals had, on average, a very high acceptance rate of 82% in Cycle 11)
  • High frequency (Bands 8, 9, and 10) in any configuration
  • Low frequency (Bands 1, 3, and 4) at long baselines (C-7 and C-8)
