As announced in the P110 call for proposals, ESO will no longer offer APEX observing time beyond Period 110. The last opportunity to submit ESO observing proposals for APEX is thus the P110 deadline on 25 March 2022, for observations in the second half of 2022. This corresponds to the end of the current APEX agreement. From 2023 to 2025, ESO will operate APEX as a hosted telescope on a cost neutral basis, but without observing time to the ESO community. Data from the remaining APEX partners taken after 2022 will also no longer be stored in the ESO archive.
