Due to planned IT maintenance access to ESO services will be only intermittent between Saturday, 23 Jul 2016 at 08:00 CEST and Sunday, 24 Jul 2016 at 24:00 CEST. In particular, we advise our users not to try to submit Phase 2 material during this period to avoid any problems.

Phase 2 Observing Preparation

Phase 2 is the step when users of ESO's telescope facilities prepare for their observations. These preparations slightly differ for those who have been granted Service Mode observations versus observers who will travel to the telescope for their Visitor Mode observations. The backbone of all observations (with the exception of APEX, see APEX Service Mode Preparation) are the Observation Blocks (OBs) which one prepares with the Phase 2 Preparation Tool, or P2PP.

Help and instructions for Phase 2 preparations is offered by different teams, depending on the nature of the observations, via web pages and email contact. Please choose one of the following links:
