The Cycle 8 2021 ACA Supplemental Call for Proposals is now OPEN!!

Sep 08, 2021

The Joint ALMA Observatory (JAO) is now accepting observing proposals for Cycle 8 that request to use the Atacama Compact Array (ACA) in stand-alone mode. Instructions on how to submit proposals can be found on the Cycle 8 Supplemental Call web page.

Users of any nationality or affiliation are invited to submit proposals before the deadline of 15:00 UT on Wednesday 6 October 2021.

Proposals submitted in the Supplemental Call will be peer reviewed using a distributed system in which each proposal team selects a designated reviewer to participate in the review process. The review process is described in detail in the Supplemental Call documentation.

Proposals with targets at any RA will be considered, but those that can be observed in the LST range 20 to 10 h are particularly encouraged. Note that 7m-Array polarization observations are not offered at this Supplemental Call. In addition, time-constrained and Target-of-Opportunity (ToO) observations are not offered at this Call for Proposals. A minimum of 1500 h will be allocated each on the 7-m Array and the Total Power Array to proposals submitted at this Call.

Information about targets that are already in the observing queue can be found on the Duplicate Observations page.

Users should note that the Supplemental Call proposal submission server will not be available for a few hours on September 27 because of scheduled maintenance. The precise downtimes will be noted on the Science Portal.
