European ARC Announcements

European ARC Announcements are provided by ESO and the European ALMA Nodes that together make up the European ALMA Regional Centre Network.

ALMA Cycle 10 Pre-Announcement

Published: 30 Jan 2023

The Joint ALMA Observatory (JAO) will start Cycle 10 observations in October 2023. A Call for Proposals (CfP) with detailed information on Cycle 10 is anticipated to be issued in April 2023 and the deadline for proposal submission is anticipated to be on 10 May 2023.  The purpose of this pre-announcement is to highlight aspects of the CfP to assist with early planning.

Early deadline for GMVA+ALMA proposals

Published: 29 Jan 2023

The ALMA Cycle 10 Pre-Announcement was recently released. As a reminder, Principal Investigators who wish to submit a proposal to ALMA for Very Long Baseline Interferometry (VLBI) observations in ALMA Bands 1 or 3 made in concert with the Global mm-VLBI Array (GMVA) at 7mm and 3 mm must also submit a proposal to the GMVA by its 1 February 2023 deadline. More information can be found here.

Meeting of ALMA Young Astronomers (2023)

Published: 28 Jan 2023

The deadline for registering for the Meeting of ALMA Young Astronomers (MAYA 2023) is approaching fast! MAYA 2023 is a conference targeted toward early career astronomers interested in ALMA, which will take place on 6th to 10th March 2023, and it will be fully on-line. Deadline for abstract submission is 15th January 2023.

The goals of the meeting are to allow the participants to present their scientific work, interact with other participants and staff working in the ARC nodes, and potentially trigger new collaborations and new projects. For details and registration, please visit this page

ALMA announces Joint Proposal agreements for JWST, VLA, and the VLT

Published: 20 Dec 2022

The ALMA observatory is pleased to announce that it has entered into Joint Proposal agreements with the Space Telescope Science Institute (STScI) for the James Webb Space Telescope (JWST), the European Southern Observatory (ESO) for the Very Large Telescope (VLT), and the National Radio Astronomy Observatory (NRAO) for the Karl G. Jansky Very Large Array (VLA).

Restart of ALMA Cycle 9 observations

Published: 19 Dec 2022

ALMA has resumed performing PI science observations following the cyber-attack. The end-to-end data acquisition and processing workflow and software were successfully re-tested prior to the restart. ALMA is currently taking observations in configuration C-3. User services are also now back online, including access to ALMA user profiles, SnooPI, and the Cycle 9 DDT submission server. As previously announced, ALMA's most compact configurations (C-1 and C-2) will not be visited again in Cycle 9.

Some Scheduling Blocks (SBs) requiring configuration C-2 were already observed in the days prior to the cyberattack. Projects with SBs in nominal configurations C-1 and C-2 that can still be observed in configuration C-3 will remain in the observing queue. As per usual ALMA policy, incomplete Cycle 9 Grade A projects will carry over into Cycle 10.

ALMA Data Reduction Training

Published: 25 Nov 2022

Following the 6th Netherlands ALMA Science Day, on Friday, 9 December Allegro will host an introductory ALMA Data Reduction Training also at Leiden Observatory. Allegro fellows will introduce CASA and ALMA data reduction techniques, share tips & tricks, and offer extensive hands-on training in data imaging and analysis. Students and postdocs are particularly welcome to attend the training, which will cover both basics and more advanced topics. The registration form will remain open until 2 December 2022.

ALMA Update on the Recovery from the Cyber-attack

Published: 18 Nov 2022

On October 29, 2022, the Atacama Large Millimeter/submillimeter Array (ALMA) suffered a cyber-attack on its computer systems, forcing the suspension of astronomical observations and the public website. This event is under investigation by local authorities.The Computing team quickly isolated the Antennas and Correlator systems and the Science Archive data systems. However, communication and other operational clusters were affected, forcing ALMA to stop all observations. Since then, email communication has been restored safely, along with new collaboration tools that enable the staff to continue their regular work.

The Crisis Management Team has developed a full-recovery plan in consultation with cyber security officers from ESO/NAOJ/NRAO. Our highest priority is to work hard to resume observations before the end of the year.
