Phase 2 Observing Preparation

Phase 2 is the step when users of ESO's telescope facilities prepare for their observations. In the ESO Period 100 the observation preparation differs slightly for users who have been granted Service Mode observations versus observers who will travel to the telescope for their Visitor Mode observations or who have time allocated in designated Visitor Mode.  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. Visitors at Paranal are asked to prepare their observations with the web-based application p2 (exceptions are VIMOS users).

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:
