The ALMA Cycle 7 Call for Proposals for scientific observations is open for submissions. 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 at 15:00 UT on 17 April 2019. It is anticipated that 4300 hours will be available on the 12-metre array time and 3750 hours on the Atacama Compact Array (ACA) (also known as the Morita Array), 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.

ALMA provides continuum and spectral-line capabilities for wavelengths from 0.32 to 3.6 mm, and angular resolutions from 0.012” to 3.4” on the 12-metre array. Cycle 7 will bring several new observational capabilities to ALMA, 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 polarisation 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.
