IMPORTANT NOTICE (11 July 2025 11:00CEST): we are currently experiencing a major issue with our p2 software that prevents the creation of new Observation Blocks, so that Phase 2 submissions cannot be made at this stage. We are actively investigating this issue and hope to restore p2 to its normal state as soon as possible. We sincerely apologize for the inconvenience.
UPDATE (11 July 2025 13:00CEST): the bug has been corrected. Please refresh the p2 page in your browser and make sure that you are using version 2.22.6 (or above) of the interface as indicated in the top-left corner of the page.
