Period 109 Telescope Allocation

Published: 22 Dec 2021

The 109th Observing Programmes Committee (OPC) met online during November 2021. Based on the committee's recommendations to the ESO Director General, a total of 2093 (10-hour equivalent) nights of Designated Visitor Mode and Service Mode observations were allocated on the VLT/VLTIVISTA, the 3.6-metre and NTT, and APEX telescopes. The submission deadline for Phase 2 Service Mode observations is Thursday 3 February 2022; see the separate announcement for further details.

On the VLT, the balance between Visitor and Service Mode in Period 109 was about 16/84, excluding filler programmes. New and ongoing Large Programmes on the VLT occupy about 18% of the allocation. The time committed to Large Programmes on the 3.6-metre and NTT is 57% and 16%, respectively.

The outcome of the time allocation was communicated to the Principal Investigators of proposals submitted for Period 109 on Wednesday 22 December 2021.
