For this Main CfP, the JAO anticipates having 4300 hours of approved science time on the 12-m Array and at least 3000 hours each on the 7-m Array and the Total Power Array. Together, the 7-m Array and Total Power Array form the Atacama Compact Array (ACA), also known as the Morita Array. Additional time on the ACA in Cycle 8 2021 will be made available later in a Supplemental CfP.

Every effort will be made to undertake observations at ALMA Cycle 8 2021 as described in this Call. However, given the on-going pandemic and its uncertain evolution through 2021 and into 2022, there may be unforeseen impacts on observatory operations in Cycle 8 2021. ALMA will keep the community informed of any significant developments.
