Current Network Architecture

First eVLBI with JIVE: September 2004 The first eVLBI test observations took place on Sept. 10, The source, , was observed at 1.6 GHz using an array consisting of Arecibo, Cambridge (UK), Torun (Poland) and Westerbork (Netherlands). The observations resulted in the FIRST transatlantic eVLBI image. Arecibo-Torun was then the LONGEST real-time interferometer baseline yet created. (Top) The 1.6-GHz continuum image of at 80 mas resolution. (Below) Visibility amplitude and phase plots between Arecibo and other EVN stations.

Data Path to JIVE  PRISANET (PR) of the Arecibo Obs./UPR.  AMPATH (US) of Florida Intl. Univ.  Abilene (US) of Internet 2.  SURFnet (NL) of SURFnet BV. Data rate: 32 Mbps, briefly sustained 80 Mbps. DAR/Formatter MK5 JIVE in2net
