Status update for the ALMA telescope

Dear colleagues,

The COVID-19 pandemic still continues to impact our lives in many ways around the world. The situation in Chile has slightly improved in the Santiago area but not yet improved in the northern area where the ALMA telescope is located. ALMA operations thus remain suspended and the timeline of resuming observations unfortunately remains uncertain. Detailed plans for the safe return to operations have been developed and regular reviews to consider starting the re-opening process of the Observatory have now started. ALMA is currently still in the Caretaker phase with small teams maintaining the safety of the ALMA equipment and infrastructure. As always, the top priority is the health and safety of all our staff.

The ALMA Regional Centers (ARCs) continue to provide support for PIs and users of archival data. The ARCs in particular assist the reduction and analysis of existing data through virtual face-to-face (f2f) support in addition to usual Helpdesk interactions. If you have any questions, want to sign up for a virtual f2f visit, or have comments or concerns related to the situation at ALMA, please contact the ALMA Helpdesk at https://help.almascience.org.

Allegro continues to actively provide support to our users. Don’t hesitate to e-mail us in case of questions or concerns.

Status update for ALMA Cycles 7 & 8

The ALMA Director, with support from all Executives and the ALMA Board, has taken the following recent decisions regarding the status of Cycle 7 and Cycle 8:

  • The start of ALMA Cycle 8 has been postponed until 2021 October. It is anticipated that the Cycle 8 Call for Proposals will open again in 2021 March.
  • ALMA Cycle 7 will continue through 2021 September, with currently non-completed projects ranked A, B and C remaining in the observing queue.

There remain many questions outstanding regarding resuming observations and accepting future proposals during these uncertain times.  ALMA is working on these questions and will provide a next update to the community in the coming weeks.

Suspension of ALMA Cycle 8 Call for Proposals

The COVID-19 crisis has continued to affect the global community, including ALMA users and staff. ALMA operations remain suspended, as announced on March 20. Under these difficult and unprecedented circumstances, the ALMA Director, with support from all Executives, has decided to suspend the submission of Cycle 8 proposals until further notice. The Cycle 8 proposal submission server will be closed as of 15:00UT on Friday, 17 April, 2020.

ALMA Executives appreciate the community has worked hard on new science ideas for Cycle 8, even under such difficult conditions. They also realize the work the community has done in generating an exciting Cycle 7 observing program. At this time, the first priority is the health and well-being of the global community. New timelines for Cycle 7 and Cycle 8 will be announced on the Science Portal in the coming weeks as the global situation evolves.

Allegro continues to actively provide support to our users. Don’t hesitate to e-mail us in case of questions or concerns.

Extension of Proprietary Times

Due to the COVID-19 crisis and its impact on the global astronomical community, the ALMA Director has made the following decision regarding proprietary times of ALMA data sets.

The proprietary period of all MOUSs that have been delivered to principle investigators (PIs), but have not become public by 19 March 2020, will be extended by three months. This implies that the proprietary period of all these ALMA data will effectively be set to 15 months, or nine months for DDT projects. 19 March was the last day that ALMA was observing before Cycle 7 observations were suspended.

For data sets that already reached the end of the proprietary time between March 19 and today, the proprietary time will be reinstated and extended for an additional 3 months. Please be aware that ALMA cannot guarantee that these data sets have not already been downloaded by archive users.

PIs of data sets that do not fall in the category defined above, who feel that their ability to work on their data within the regular proprietary period is impacted by the COVID-19 crisis, are requested to submit a ticket to the “Proprietary Period Extension Requests” Department of the ALMA Helpdesk. ALMA will handle these requests in a fair and lenient manner as we are committed to support our users as much as possible during this stressful time.

Updates on this policy may be posted on the Science Portal in the future.

Don’t hesitate to e-mail Allegro in case of questions or concerns.

ALMA Proposal Preparation Day (online material)

IMPORTANT UPDATE: The ALMA Director, along with the regional partners, have decided to delay the proposal deadline for the ALMA Cycle 8 Call for Proposals to NO EARLIER than 15 UT on 19 May, 2020. Therefore, Allegro has decided to postpone the Proposal Preparation Workshop of March 26 to a later date, approximately 3 weeks before the actual deadline (when this is decided).

For those who want to get started on their ALMA proposal still on the original schedule, we are providing a series of pre-recorded presentations:

which can be found below or on our YouTube channel.

Everyone is encouraged to e-mail Allegro with any questions that they may have after watching these presentations. We will answer all questions, either by e-mail or via an online session, and also collect Frequently Asked Questions in a constantly updated document. For your convenience, we have also created a toolbox with useful links to help you prepare your proposal.

We would like to highlight the possibility to submit Large Programs on both the main array (>50 hours) and ACA stand-alone (>150 hours). PIs who are considering a Large Program are encouraged to contact Allegro early to optimize your program and explore the many ways we can support your project.

Survey: ALMA User Experience

The End-to-end User Experience Working Group are a team of staff from the different ARC nodes who are seeking feedback on how to improve the ALMA user experience, from the Call from Proposals stage, through working with ALMA data (be it a project you proposed or Archival data). The ultimate goal is to identify and address any issues which prevent the best user experience and affect scientific output. You can help us by filling in our survey at the following http://eso.org/almaexperience

Your feedback will be very much appreciated! You can also contact the ARC nodes in Europe directly if you want to discuss particular aspects of your user experience.

If you want to know more about the ALMA User Experience Survey in the Netherlands, please contact Allegro by sending your email to alma@strw.leidenuniv.nl and/or guzmanl@strw.leidenuniv.nl

Changes to how to write your ALMA proposal for Cycle 8

For Cycle 8, ALMA is adopting dual-anonymous review. This means that the proposers do not know who the reviewers are, and the reviewers don’t know who is on the proposing team. This has important consequences on how you write your proposal!

ALMA has put together a document with guidelines. Consequently, any text that can identify the proposing team is not allowed. Attempts to convey the identify proposing team in the text may lead to your proposal being disqualified.

What you need to do:

  • Read the guidelines.
  • Write your new proposal according to these guidelines, and rephrase the text of proposals that are re-submissions from previous cycles.

A presentation describing how to write an anonymous ALMA proposal can be found below (pdf file).

Allegro is organizing a proposal preparation workshop on Thursday March 26, where these requirements will be discussed together with other technical information about ALMA Cycle 8. You can register for the Proposal Preparation Day at the following link.

ALMA-VLBI QA2 Workshop– Leiden Lorentz Center, 24-28 February 2020

Allegro is hosting a QA2 training workshop for phased-ALMA data acquired during VLBI observations, which will be held in Leiden (the Netherlands), on February 24-28 2020.
VLBI is an observing mode offered since Cycle 4, and the first observations were conducted in Apr 2017. The QA2 process for VLBI projects is significantly more complex than the procedure for standard projects, requiring a close loop between ARCs, JAO and VLBI correlators.
The main goal of the workshop is to train ALMA astronomers so that the QA2 work load can be distributed across different regions. The training workshop will involve hands-on work on past cycles datasets.
This workshop is restricted to the trained QA2 analysts in ALMA Regional Centers (ARCs).
