• Present poster "All of the Sky: HEALPix Density Maps of Gaia-scale Datasets from the Database to the Desktop" at ADASS XXVI conference, Trieste 16-20 Oct 2016 (M.Taylor et al.) https://arxiv.org/abs/1611.09190

• New menu structure for Gaiaverse
• Eduard expressed interest on adding Euskera on Gaiaverse.
• Structure of new pages related to DR1 and selection of contents.
• Preparation of the portal to make the catalogue available from the homepage.
• Brainstorming of particular actions to cover the DR1 launch on September 14th.

These pages have been all translated into 9 of the 12 languages available up to this moment on Gaiaverse: English, French, German, Italian, Spanish, Catalan, Slovene, Croatian and Portuguese.

We've been working on adding Euskera into the platform as a new language as well. It is not complete yet, but for its preparation we needed the translation of 26 words, 16 sentences and 10 mini texts, plus the "About Us" description and other news considered of interest.

In total, by the end of September 2016 Gaiaverse already has 13 languages.

While preparing the portal for this DR1, some other modifications have been introduced:

• featured news on the homepage
• menu adjustment, as the incorporation of new pages (Gaia DR1) forced others to jump into a 2nd line. The problem has been fixed successfully.
• introduction of improvements on the "Filter" button in Resources.
• new field in Tools to make the incorporation of a new link available.

This is illustrated with the top ten most visited pages. As usually, the homepage is at the top, but for the first time the second position is occupied by a page which is not the home: the Gaia Data Release 1 (DR1). Resources rank third.

The same pattern is followed by landing pages, understood as those pages a user arrives at after clicking a hyperlink. Once again, the homepage ranks first, followed by the DR1 in different languages (English, French, German, etc.).

Spain, USA and UK are the three countries with more sessions initiated on Gaiaverse. Accordingly, English and Spanish are the preferred languages on Gaiaverse (45.67% and 11.33% respectively); even if German and French have important percentages as well (5.97% and 4.39% respectively).

Regarding traffic on Gaiaverse during July-September 2016:

• Organic search: 36.16%
• Referral: 29.17%
• Direct: 25.17%
• Social: 9.50%

First Gaia Data Release

It is worth mentioning that September has been a great month in regards to visibility thanks to the release of the first Gaia data catalogue, that in terms of dissemination, represented:

T7.1 - Coordination of dissemination activities

T7.2 - Community portal infrastructure

T7.3 - Community portal, outreach and academic activities
