The European ARC Network organises an ALMA Science Archive School at the Italian ARC node headquarters in Bologna, on 5-7 October 2022. To register for the meeting please make use of the registration form, that will remain open until July 15th 2022.

The deadline for submission of the Stage 1 ranks and reviews of the ALMA Cycle 9 proposals is Wednesday, June 1 at 15:00 UTC. If ranks and reviews are not submitted by the Stage 1 review deadline, the proposal for which you are acting as the designated reviewer will be rejected.

The next talk of the series will be presented by Nicolas Biver (LESIA, Observatoire de Paris), on June 1st at 14:00 CEST, who will address the question: What do comets tell us about the origin of Earth? The talk will be broadcast on theYoutube channel of the European ALMA Regional Centre network.

The European ARC Network invites users to an online training on simulating ALMA data with CASA on June 17th, 11:00 CEST [Zoom link]

The European ARC Network invites users to an online training on Using ALMA archival data - A Primer on May 20th, 11:00 CEST [Zoom link].

The Proposal Handling Team is organising a series of online sessions in which they will present the Cycle 9 distributed peer review process and guidelines for reviewing proposals. The sessions will consist of a presentation followed by a live question and answer session. Sessions targeted to the European community will take place:

Thursday May 05, 13:00 UTC   and  Tuesday May 10, 15:00 UTC.

Since Oct 2019, the EU ARC is offering its users the "CalMS" service which has so far provided 155 unique users with more than 1750 calibrated MeasurementSets (MSs). As its popularity increases, further features are added to the system. Users can now:

• immediately produce line images and cubes making use of the continuum subtraction performed by the pipeline,
• request the calibrated data for particular calibrator targets,
• identify MOUSs which belong to the same Group OUS.

Current ALMA products can be characterized as "science-ready calibration, informative imaging". This means that PIs and archive users may need to repeat the imaging process to obtain products that are optimised for their specific scientific analysis. The purpose of this new development study is to investigate the potential interest of generating "science-optimised" products. These Advanced Data Products may include:

• science-grade products for every ALMA observing project;
• high-level science products based on, e.g., the combination of different observations of the same object;
• derived products such as catalogues, spectra, SEDs, etc.
