VLTI Community Days: ESO Headquarters, Garching, Germany, 8–10 March 2017
VLTI Winter School: ESO Headquarters, Garching, Germany, 6–8 March 2017

The Very Large Telescope Interferometer (VLTI) is currently undergoing deployment of the second generation instruments and infrastructure upgrades, and the K-band multi-beam combiner instrument GRAVITY is being commissioned. The VLTI Community Days are a unique opportunity to get together and reflect on the present and plan for the future.

Data Release 4 of Images and Source Lists from VVV

Published: 06 Feb 2017

The VISTA Variables in the Via Lactea (VVV) survey fourth data release (DR4) provides VISTA tile images and source lists in ZYJHKs filters, processed by the Cambridge Astronomical Survey Unit (CASU), for a total sky coverage of 560 square degrees. DR4 contains science data products from observations in the period 1 October 2013 – 15 October 2015, and also science data products from observations in September 2010 to September 2013 not included in the previous release.

Announcement of 3mm VLBI in ALMA Cycle 5

Published: 19 Jan 2017

It is expected that phased ALMA will participate in some Global 3mm VLBI Array (GMVA) observations during ALMA Cycle 5 (1 October 2017 – 30 September 2018); see the full announcement for further details. Any GMVA proposal requesting phased ALMA during Cycle 5 must be submitted by the 1 February 2017 deadline; see the proposal call .

Availability of ALMA Solar SV Data

Published: 19 Jan 2017

The latest release of ALMA Science Verification (SV) data will contain observations of the Sun obtained during the Solar commissioning campaigns in 2014 and 2015. The release contains mosaics and single pointing observations in quiet and active solar regions at Band 3 and 6 with the 12-metre, 7-metre and total power arrays. The data are available under ALMA Science Portal SV.
