Record number of observing hours in Cycle 10

The ALMA Observatory is excited to announce that an impressive total of 4250 hours of science-quality data (QA0 PASS observations) were successfully acquired on the 12-m Array during Cycle 10, significantly exceeding the previous record of 3787 hours acquired during Cycle 5! Moreover, record numbers of hours were also achieved on the 7-m (3769 hours) and Total Power (2723 hours) arrays. 

This important milestone is made possible by the hard work and dedication of observatory staff across the ALMA partnership: the Joint ALMA Observatory and the partner regions in East Asia, Europe and North America. The steady progress shown in the chart below highlights ALMA’s journey towards this significant milestone.
