APEX - Call for proposals for Period 108

The European Southern Observatory (ESO) invites proposals for observations at ESO telescopes during


Period 108 (1 October 2021 - 31 March 2022)


Please refer to the Call for Proposals for Period 106 for instruments offered in Period 106, relevant for DDT and Special Call proposals during Periods 106 and 107. Due to the pandemic events, the regular Call for Proposals for Period 107 was suspended, and instead a Special Call for Period 107 was issued. Please check there whether the DDT or Special Call channel would be appropriate for a proposal for Period 107.
