A report on ALMA Cycles 1 & 2 with observing and completion statistics, data reduction and delivery, and publication statistics is available.
Cycle 4 started on 30 September 2016 and continues with the array in the more compact configurations transitioning from C40-4 (0.93” beam at 100 GHz; 704 m longest baseline) to C40-3 (1.3” beam at 100 GHz; 460 m longest baseline) as austral summer begins. The very good weather has allowed high frequency observations (above 400 GHz). Data processing and delivery is proceeding smoothly using the Cycle 4 calibration and newly commissioned imaging pipelines and the Cycle 3 backlog is shrinking. Deliveries of Cycle 3 and Cycle 4 data products continue.
