The ALMA Director, on behalf of the Joint ALMA Observatory (JAO) and the partner organizations in East Asia, Europe, and North America, is pleased to announce the ALMA Cycle 8 2021 Call for Proposals (CfP) for scientific observations to be scheduled from October 2021 to September 2022. More detail can be found on the ALMA Science Portal.

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.

A comprehensive description of the ALMA observatory and its components can be found in the ALMA Technical Handbook. For information not provided at the Science Portal, proposers may submit a Helpdesk ticket. Registration at the ALMA Science Portal is required to submit a Helpdesk ticket.

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.
