On behalf of the Joint ALMA Observatory and the partner organizations led by NAOJ in East Asia, ESO in Europe, and NRAO in North America, the ALMA Director, Sean Dougherty, is pleased to announce the ALMA Cycle 9 Call for Proposals for scientific observations to be scheduled from October 2022 to September 2023. It is anticipated that 4,300 hours of the 12-m Array time and 4,300 hours of the Morita Array (a.k.a. Atacama Compact Array – ACA) time will be available for successful Principal Investigators proposals in Cycle 9. The submission deadline is April 21 at 15:00 UT.

"The new capabilities available for this cycle will allow astronomers to observe for the first time with longer baselines at high frequencies” explains Elizabeth Humphreys, Head of the ALMA Department of Science Operations. “I'm very excited to see all the new science that will be done with ALMA in the coming years".

ALMA ambassadors from the North American ALMA Science Center (NAASC, NRAO) have arranged a series of targeted workshops at institutes across the U.S. and an abbreviated webinar series that is more broadly targeted – including dedicated presentations in Spanish. For more information about these sessions and the registration page can be found here.

The European ALMA Regional Centre (ARC) network is organising a series of virtual and in-person proposal preparation events across Europe, related to the Cycle 9 call for proposals. A full overview of the activities as well as information about participating can be found here.

The East Asia ALMA Regional Center and its nodes in Japan, Taiwan, and Korea organize meetings to assist ALMA users for their preparations of Cycle 9 proposals. Each regional meeting is going to cover content optimized for the local user community. Information can be found here (Japan), here (Taiwan), and here (Korea).
