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.

Regarding Cycle 10, due to the disruption caused by the cyber-attack, the Cycle 10 pre-announcement will now be issued in the week of 16th January.
