A visibility amplitude calibration error that affects fields containing strong line emission has been discovered in ALMA interferometer observations up to and including Cycle 7.

ALminer (ALMA archive mining and visualization toolkit) is a novel Python-based code that enables users to efficiently query, analyse, and visualize the ALMA Science Archive. Users can programmatically query the archive for positions, target names, or any other keywords in the archive metadata (e.g. proposal title, abstract, scientific category) in a simple way. For more information about how to install and use ALminer, please visit the documentation or GitHub pages.

The training series I-TRAIN organised by the European ARC Network will be paused during the European summer months and then resumed in the autumn. In the meantime, videos and materials of the past sessions can be accessed from the ALMA Science Portal, including the last trainings on self-calibration and polarisation observations with ALMA.

The UK ARC Node at the Jodrell Bank Centre for Astrophysics invites applications for a postdoctoral research associate position to work as a support astronomer for UK ALMA users. The closing date is 09 August 2021.

On 2 July 2021, the EU ARC CalMS service provided the calibrated dataset (MOUS) number 1001.The service was launched in October 2019 and has now been extended to be capable of serving up to several 100 MOUSs per month.

The ALMA Science Archive query interface can now show all sources from SIMBAD and NED that fall into any of the ALMA observations. It is furthermore possible for the users to search for particular categories of sources.

Registrations are open for "The ALMA 2030 Vision: A next generation of front-end receivers" workshop. Abstracts can be submitted here until July 16, 2021. Potential participants can inquire with the organization about late submission of abstracts, via ALMA_FED_2021@eso.org.

Over the past several weeks, ALMA has continued to conduct PI science observations on a best-effort basis while the recovery of the Arrays has been ongoing. The first set of antenna relocations was completed on May 10, 2021, moving the 12-m Array into the C43-6 configuration. In addition, PI science using eight antennas on the 7-m Array began on May 18, 2021. The plan is to go through all remaining configurations (C43-7 to C43-10) by the end of Cycle 7, although for a shorter duration than originally planned for each configuration.
