The deadline for proposal submission for Period 106 (1 October 2020 - 31 March 2021) was 23 April, 2020, after an extension of four weeks due to the COVID-19 crisis. 1070 valid proposals were submitted, including 47 Large Programmes, which is the largest number of Large Programme proposals ever submitted in a single period.

In Paranal, the telescope with the highest oversubscription is Antu (UT1), with a total request of 650 nights, followed by Yepun (UT4; 611 nights). Following the steady trend observed during the last semesters, the request for Service Mode still exceeds 80%.
