MeerKAT science operations and lessons learned

The MeerKAT telescope is a radio interferometer consisting of 64 13.5 m diameter dishes. It started its first science observations in April 2018, while commissioning of new observational modes continues up to now. We discuss the processes and develop over the course of the last five years, as we adapted to the ways that telescope usage evolved. The science program consists of a mix of large Survey projects (through a once-off call for proposals), open time proposals solicited through yearly calls, Director's discretionary time and science verification projects. As the large Survey projects reach completion, the emphasis of science operations is shifting to open calls, with many new users introduced to the telescope each year. Additional challenges are being experienced in providing support to a growing user base and enabling access to a rapidly growing archive of observations exiting their proprietary periods.
