ALMA Cycle 7 Call for Proposals in now open
19 March 2019

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 that the ALMA Cycle 7 Call for Proposals for scientific observations is now OPEN!

ALMA Cycle 7 is currently scheduled from October 2019 to September 2020. Users of any nationality or affiliation are invited to to submit proposals before the deadline of 15:00 UT on Wednesday 17 April 2019.

It is anticipated that 4300 hours of the 12-m Array time and 3750 hours of the Atacama Compact Array (ACA) time, also known as the Morita Array, will be available for successful proposals from Principal Investigators (PIs) in Cycle 7 (including a supplementary call).  Proposals must be prepared and submitted using the ALMA Observing Tool (OT), which is available for download from the ALMA Science Portal. Proposals will be assessed by competitive peer review by a single international review committee.


The ALMA Cycle 7 proposal submission deadline is 15:00 UT on Wednesday, 17 April 2019.


ALMA provides continuum and spectral-line capabilities for wavelengths from 0.32 mm to 3.6 mm, and angular resolutions from 0.012” to 3.4” on the 12-m Array. Cycle 7 will bring to ALMA several new observational capabilities, including observations in Band 7 out to 16.2 km baselines, Solar observations in Band 7 in the two most compact configurations and in Band 3 in one additional configuration (C43-4), an improved sensitivity limit for full spectral resolution linear polarization observations and improved observing efficiency for spectral scans.

The ALMA Proposer’s Guide provides an overview of significant changes made in both the technical capabilities and observing strategies for Cycle 7, an overview of the ALMA organisation, the types of proposals offered in Cycle 7, information on proposal planning and submission, an overview of the offered technical capabilities, and guidelines for writing a Technical Justification. A comprehensive description of the ALMA observatory and its components can be found in the ALMA Technical Handbook.
