Status of ALMA Observations and Relocation to Long Baselines

The ALMA Observatory has experienced back to back severe winter storms, making it difficult to recover the 12-m array for PI observations. This has had an even more detrimental impact on the relocation to the long baselines. Many roads are blocked with 2 meters of snow, high winds often return snow to the cleared locations, and snow is compacting into ice. We have returned to routine observations utilizing the 7-m and Total Power Arrays, and we are working hard to clear the remaining antennas to return to 12-m array PI science and reconfigure to the longest baselines. We will issue an update regarding the revised configuration schedule in the coming weeks

Cycle 5 Phase 2 deadline

The Cycle 5 Phase 2 deadline by which approved projects need to be submitted to the archive is anticipated to be Sept 7th 2017.

Users can delegate the submission of the Phase 2 material in case of unavailability. They can do so by selecting a delegee (for each project) in their user profile.

Guidelines to PIs will be made public in July.

Supplemental Call for Proposals to use the 7-m Array in Cycle 4

The ALMA Director announces that the Joint ALMA Observatory (JAO) will accept observing proposals that request to use the 7-m Array in the remainder of Cycle 4, which ends on September 30, 2017. This proposal call enables the community to propose projects that will fill in undersubscribed regions of the observing queue for the 7-m Array. Up to 800 hours on the 7-m Array will be allocated through this opportunity.

For more details on this supplemental call please visit the ALMA Science Portal.

ALMA Cycle 5 Call for Proposals in now open

The ALMA Director, on behalf of the Joint ALMA Observatory (JAO) and the partner organizations in East Asia, Europe, and North America, is pleased to announce the ALMA Cycle 5 Call for Proposals (CfP) for scientific observations to be scheduled from October 2017 to September 2018.

The ALMA Director, on behalf of the Joint ALMA Observatory (JAO) and the partner organizations in East Asia, Europe, and North America, is pleased to announce the ALMA Cycle 5 Call for Proposals (CfP) for scientific observations to be scheduled from October 2017 to September 2018. It is anticipated that 4000 hours of the 12-m Array time and 3000 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 5. 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 5 proposal submission opens at 15:00 UT on Tuesday, 21 March 2017.

The ALMA Cycle 5 proposal submission deadline is 15:00 UT on Thursday, 20 April 2017.

ALMA provides continuum and spectral line capabilities for wavelengths from 0.32 mm to 3.6 mm, and angular resolutions from 0.018” to 3.4” on the 12-m Array. Cycle 5 will bring to ALMA several new observational capabilities, including full polarization observations in Band 4, baselines out to 16 km and simultaneous observations between the 12-m and 7-m Arrays. Starting in March 2018, also as part of Cycle 5, ALMA will offer observations in Band 5 (proposals for the latter observations are due at the regular Cycle 5 submission deadline).

For comprehensive information of this Cycle 5 Call for Proposals please consult the ALMA science portal.

Special Session SS20 at EWASS – Prague, 26 – 30 June 2017

The European Week of Astronomy and Space Science (EWASS) Special Session No. 20, held on the first day (26 June) of the conference, will be devoted to the three particular modes of observing with ALMA that demonstrate the unique capabilities of the facility: High-Frequency Observations (specifically in Bands 8, 9 and 10); High-Angular-Resolution Observations with baslines up to 16 km; Solar Observations. Further details on the S220 site.

  • Description

  • Program
  • Participants
  • Directions



    This event will feature presentations on exciting recent results from ALMA by astronomers from the Allegro user community, the latest news from ALMA, and a plenary discussion on expectations and wishes for user support and any other ALMA-related topics. We will conclude the day with the Leiden Observatory General Astrophysics Colloquium that for the occasion of this workshop will have a special ALMA theme, and will be delivered by Dr. Mario Tafalla (OAN Madrid) on ‘ALMA observations of protostellar jets. Trying to understand the mechanism of outflow acceleration’.
