The European ARC Network invites users to a presentation on the first public release of the ALMA uv coverage assessment tool "assess_ms" on 13 June, 11:00 CEST (Zoom link).

Allegro, the ALMA Regional Center node in the Netherlands, is pleased to announce that it will be hosting the second European ALMA School on 26 - 30 January 2026. The School will be held at Leiden University in the Netherlands and will feature a week of hands-on training in ALMA data processing and analysis, guided by world experts from the European ARC network. A website with more information about the location, school program, and how to register will open in June.

The European ARC Network invites users to a second I-TRAIN on VLBI data using ALMA as a phased array on 16 May at 10:00 CET (link to Zoom).

This tutorial will provide an introduction to accessing and dealing with VLBI data from networks which include ALMA as a phased array. We will first cover accessing phased data and what is on the ALMA archive.  Then ALMA's role in the Global Millimeter VLBI Array (GMVA), how to obtain PI and/or archival GMVA data, and how to calibrate them will be discussed. Finally, we'll look at EHT data, how to obtain those publicly available datasets, and how to calibrate them.

ESO is pleased to announce that it will issue a call for proposals for ALMA development studies for ALMA upgrades in the course of the month of May, with an expected deadline at the end of August. This call will only be open to ESO member state institutes. Full details of the call will be announced in the May ARC newsletter. ESO will organize an information day on Tuesday 27 May 2025 (in-person registration deadline: 15 May 2025). 

ALMA Cycle 12 Call for Proposals for scientific observations is now OPEN! 

ALMA Cycle 12 is currently scheduled for observations from October 2025 to September 2026. Users of any nationality or affiliation are invited to submit proposals before the deadline of 15:00 UT on Thursday 24 April 2025.

The European ALMA Regional Centre (ARC) network is organizing virtual and in-person proposal preparation events related to the Cycle 12 Call for Proposals across Europe.  A complete overview of the activities and information about participating can be found here. 

The Czech ALMA Regional Centre node is organising a workshop aimed to prepare the local communities for the upcoming ALMA Cycle 12. The focus will be on the preparation of observations, capabilities of ALMA in Cycle 12, important observation parameters, examples of observing proposals, work with the Observing Tool application for the preparation and submission of proposals, etc.

ALMA is exploring key upgrades to enhance its sensitivity, resolution, and imaging capabilities, focusing on transformative advancements that will unlock its full scientific potential. As part of an ongoing ESO ALMA development study aimed at advancing ALMA's capabilities, the community workshop "Unlocking ALMA's Potential with Focal Plane Arrays" will take place on September 2 - 4, 2025, at MPIfR, Bonn.This event will explore the scientific drivers and technological innovations behind focal plane arrays (FPAs) - a breakthrough that could significantly expand ALMA's field of view and mapping speed
