Phase 2 Observing Preparation

Phase 2 is the step when users of ESO's telescope facilities prepare for their observations. 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 web-based application p2.

Visitor at La Silla Observatory are asked to prepare the OBs with the Phase 2 Preparation Tool, or P2PP. Please note that we are in the process of upgrading La Silla Phase 2 preaparation to the same web application p2 used at Paranal. More information will become available once deployment is completed.  

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:
