The ALMA Director, on behalf of the Joint ALMA Observatory and the partner organizations in East Asia, Europe, and North America, is pleased to announce the ALMA Cycle 8 2021 Call for Proposals for scientific observations to be scheduled from October 2021 to September 2022. It is anticipated that 4,300 hours of the 12-m Array time and 3,000 hours of the Morita Array (a.k.a. Atacama Compact Array – ACA) time will be available for successful  Principal Investigators proposals in Cycle 8. The submission deadline is April 21, 2021, at 15:00 UT. Additional time on the Morita Array in Cycle 8 2021 will be made available later in a Supplemental CfP.

For more information on the submission process visit the ALMA Science Portal.

Ambassadors of this radio telescope in the North American ALMA Science Center (NAASC, NRAO) have arranged a series of public talks and tutorials. The objective is to provide information on the latest ALMA capabilities, revision changes to the proposal review process, and support new users in making the best science with one of the world’s best telescopes

The series contains six talks with Q&A sessions and three sessions with a significant demonstration or operational experience; each will last around an hour. These events will be entirely virtual, and each topic will be presented multiple times from March 22 to April 5, 2021, to make it as easy as possible to get the information needed for the proposals. Several talks will be offered in Spanish or with Spanish-language speakers available for Q&A, discussion, and assistance.

People must register for these free talks, and hands-on/demo sessions (limited slots available) here:

East Asia ALMA Regional Center in Japan, Taiwan, and Korea organizes meetings to assist ALMA users for their preparations of Cycle 8 2021 proposals. The meetings cover the timeline, observing capabilities, and new proposal review process in addition to other information that may be useful for the proposal planning. Each regional meeting provides content optimized for the local user community, including an online hands-on session on how to use the Observation Tool. These meetings are intended from students to faculty, and anyone who is interested in using ALMA.

  • Korea: Townhall Meeting for Cycle 8 Proposal Preparation
    March 18-19, 23

The European ALMA Regional Centre network is organising a series of community events in preparation for the Cycle 8 2021 proposal deadline. During these events the nodes in the ARC network will provide the users with an overview of the (newest) ALMA capabilities, demonstrate how users can propose for ALMA time, discuss the double anonymous and distributed peer review process, and be available for Q&A. The nodes will additionally make video tutorials and online material available. These videos will present the basics of ALMA and interferometry and how to propose for ALMA time. Furthermore, all nodes in the European ARC network are open for one-to-one proposal preparation support for both novice and expert ALMA users. Please contact your local node or the ALMA Helpdesk if you want to make use of this. A full overview of the events organised by the European ARC can be found on the European ARC network pages.
