LIGO-VIRGO Gravitational Wave: Public Release of ESO Follow-up Observations

Published: 17 Oct 2017

The detection of the Gravitational Wave by the LIGO-VIRGO observatory network, as well as a gamma-ray source, on 17 August 2017 has resulted in one of the largest Target of Opportunity campaigns at ESO. Observations with several La Silla Paranal Telescopes led to the discovery of the first electromagnetic counterpart of a Gravitational Wave event. In addition, the Observatory carried out mid-infrared imaging with NACO (in the L' band) and VISIR (at 8.9 microns), albeit no source was detected. ESO and several of the observing teams involved have now made their datasets from this event publicly available.

All NACO and VISIR raw images, as well as reduced data from VISIR are publicly available through the ESO Science Archive under programme ID 60.A-9392. The VISIR data release includes coadded images and error maps and is accompanied by a comprehensive description.

HAWK-I/GRAAL Science Verification: Call for Proposals

Published: 17 Oct 2017

GRAAL is part of the Adaptive Optics Facility (AOF), and associated with the Deformable Secondary Mirror (DSM) and the 4 Laser Guide Star Facility (4LGSF). It defines an AO system developed to increase the performance of the HAWK-I instrument. Commissioning is proceeding and Science Verification is planned for January 2018, for which applications are invited. The call for proposals for HAWK-I/GRAAL can be found here.
The deadline for proposal submission is 31 October 2017, 18:00 CET.

ESO Public Spectroscopic Surveys with ARO Telescopes

ESO Period 101 Proposal Submission Statistics

Published: 13 Oct 2017

The deadline for proposal submission for Period 101 (1 April 2018 - 1 October 2018) was 28 September 2017. 899 valid proposals were submitted, including 16 Large Programmes, of which two are GTO Large Programmes. The number of proposals for P101 is very similar to that of periods 91 (893), 92 (892), 93 (898), 94 (901), 98 (901), 99 (887) and 100 (895). This confirms the leveling off observed after the peak of periods 95 (934), 96 (960) and 97 (1024).

Paranal Observatory Eavesdropping Mode

Published: 12 Oct 2017

As of 1 October 2017, users of designated visitor mode programs are able to view from their computer at home the relevant operation panel in the Paranal control room, via the Paranal Observatory Eavesdropping Mode. Access credentials will be provided by the mountain staff in advance of the run. Further details are available via the Paranal Science Operations page.

New Features of the ESO Telescope Bibliography Database

Published: 12 Oct 2017

ESO's telescope bibliography telbib ( has been enhanced resulting in a number of new features. In particular, the updated interface provides more information about which data were used in a particular paper, and enables access to data products as well as raw data.

ALMA: Updated Configuration Schedule for Cycle 5

Published: 12 Oct 2017

The anticipated configuration schedule for Cycle 5 has been modified from that posted in the Proposer's Guide and the updated schedule is available via this link. The most significant change is that Cycle 5 will begin in the configuration C43-10 instead of C43-7, and then move to more compact configurations.
