Due to planned IT maintenance between Saturday, 15 May 2021 at 08:00 CEST/02:00 CLT and Sunday, 16 May 2021 at 24:00 CEST/18:00 CLT, ESO services that rely on Database Management Systems, the Scientific Archive, and Internet connectivity on all ESO sites, could be subject to intermittent outages. Full services cannot be guaranteed before Monday 17 May. We apologize for any inconvenience caused.

Period 107

Following the suspension of the regular Call for Proposals for ESO Period 107 due to the ongoing COVID-19 pandemic, and as previously announced, ESO has issued a Special Call (SC107) for the submission of projects consisting of novel and urgent observations that must be executed during P107 (1 April  - 30 September 2021). Upon positive decision and scheduling of proposals accepted within the Special Call for P107, the users should proceed with preparation and submission of their observing material.

Period 106 users (including the authors of Director's Discretionary Time proposals approved during Period 106) should continue to follow the procedures presented at this link.

Service Mode Guidelines for Period 107

This page and the links in the left menu provide the general information necessary to complete the Phase 2 preparation for Service Mode programmes at the VLT/VLTI, VISTA and VST.

This information has been updated for Period 107. Period 106 users (including the authors of Director's Discretionary Time proposals approved during Period 106) should continue to follow the Period 106 procedures.


For P107 there is no formal Phase 2 deadline. A prompt submission of the Phase 2 material is essential to ensure success of the observations.

The observations of your run can only start once all the steps of the Phase 2 process are completed, including approval of your material by an ESO Support Astronomer. The earlier you submit the material the faster the process will be.

Introduction

The easiest way to prepare the phase 2 material of your observations is to choose the instrument of your interest in the Instrument Menu on the right and then follow the topics given in the list on the left or to choose the Phase 2 Instrument Overview Table.

The web application p2 must be used for Phase 2 material preparation for all Paranal observing runs. Please check our help section about p2 for for more detailed information including instructions on how to notify ESO when your material is ready. Observation preparation for La Silla is now done with a "cousin" of p2 called p2ls.   

Here you can also check a 5 min. video guiding you through the whole process of preparing and submitting an OB and a README with p2.

Updated Phase 2 Delegation

It is possible for the PI of an observing run to allow (an)other user(s) to create the OBs, READMEs, etc. using their own User Portal account by delegating access to Phase 2 preparation to them.

The delegate can be anyone with a registered User Portal account. A different person can be chosen as the delegate for different runs of the same programme. Delegating Phase 2 does not remove Phase 2 access permissions from the PI him/herself. Thus, PIs who use Phase 2 delegation are kindly asked to coordinate Phase 2 preparation between themselves and their delegate(s). Delegation can be viewed and administered though the Access Control ESO web page.
Once a user has been granted Phase 2 permissions for a run they will see the run in p2 (with a small green arrow distinguishing it as a delegated run; same in p2ls) after logging in with their own credentials.
