Shaping ESO2020+ Together: Users Poll

Published: 19 Dec 2014

The ESO Science Prioritisation Working Group has been tasked with reviewing the ESO programme from a scientific perspective. To tension the current and planned programme against new possibilities, the Working Group has today launched a poll, so that you can share with us your scientific priorities.

Phase 2 for Period 95

Published: 18 Dec 2014

The allocation of ESO telescope time for Period 95 is expected to be emailed on 22 December 2014. With the release of the telescope schedule, preparation of Service Mode (SM) observations (Phase 2) starts. The deadline for the submission of the Phase 2 material for Period 95 observations is 5 February 2015 for all instruments except VISIR.

SPHERE Science Verification

Published: 17 Dec 2014

SPHERE Science Verification (SV) took place from 4 to 11 December 2014 on VLT UT3. Out of 67 submitted proposals, 40 programmes were scheduled for a total of 88.4 hours of observations. Nineteen programmes were completed, with an additional 9 programmes receiving partial data sets. Some more SV time is planned in February 2015 and it is hoped to undertake some of the remaining 12 observing programmes.

E-ELT Two-Phase Construction

Published: 17 Dec 2014

As announced in the Organisation Release eso1440, the ESO Council has approved the construction of the European Extremely Large Telescope (E-ELT) in two phases and authorised spending of around one billion euros for the first phase. This first phase will cover the construction costs of a fully working telescope with a suite of powerful instruments and first light targeted in ten years. The context for this decision is reported in an article (PDF) in the December issue of The Messenger.

Exchange of FORS2 Atmospheric Dispersion Corrector

Published: 16 Dec 2014

The coatings of the FORS2 linear atmospheric dispersion corrector (LADC) prisms have degraded, so it was decided to replace them with the uncoated prisms of the twin FORS1 LADC. The exchange took place on 10 November 2014 and the performance of the prisms has been extensively tested.
