ALMA Cycle 12 Call for Proposals (CfP) for scientific observations to be scheduled from October 2025 to September 2026 is open. For this CfP, the JAO anticipates having 4300 hours of approved science time on each of the 12-m, 7-m, and the Total Power arrays. Together, the 7-m Array and Total Power Array form the Atacama Compact Array (ACA), also known as the Morita Array. 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)
Submission deadline: 15:00 UTC on Thursday, 24 April 2025
