The deadline for proposal submission for Period 99 (1 April – 1 October 2017) was 29 September 2016. 883 valid proposals were submitted, including 22 Large Programmes, of which one is a GTO Large Programme. The number of proposals for P99 is the lowest received in the last 7 periods. The time request also went down, while the number of proposals per PI remained constant. The number of normal proposals is slightly increased from P98, while Large and GTO proposals decreased. The time request decreased for almost all telescopes.
