e-VLBI Call for Proposals
Proposals for science use of the EVN's developing e-VLBI real-time VLBI capability are invited. Full details are available in the e-VLBI call for proposals. See the available frequency bands and e-VLBI array in the e-VLBI status table.

A "slide-show" describing e-VLBI and the e-EVN project is now available (PDF format).4th EVN-NREN Meeting
The 4th meeting of the eVLBI Proof-of-Concept (PoC)
contact group was held at Exchange Avenue, Schiphol Airport on 12th October 2005.
The Minutes were prepared by Tony Foley. The agenda section has links to presentations.
Bandwidth Control Test
Network monitoring tool BWCTL ("Bandwidth Control") has been deployed around Europe to enable diagnostic measurements to be made during eVLBI experiments. A trial was staged on Friday 4th February with Onsala, Jodrell Bank, Cambridge, Torun and Medicina participating. Snapshots from the GÉANT Backbone Weathermap and BWCTL Results of the test can be viewed in Powerpoint and PDF formats. Synagon graphs, from data collected by DANTE, can be downloaded in a zip file.
3rd EVN-NREN Meeting
The 3rd meeting of the eVLBI Proof-of-Concept (PoC)
contact group was held at Exchange Avenue, Schiphol Airport on 28th January 2005.
The Minutes were prepared by John Chevers of DANTE. The agenda section has links to presentations.
The first eVLBI science observations have taken place. Read the Press Release. Also available in PDF. (4 Oct 2004)
Real-time EVN imagingThe latest real-time EVN image has been produced, this time using four telescopes including the 305-m Arecibo dish. (20 Sep 2004)
First real-time EVN image producedThe first real-time EVN image was produced yesterday from observations carried out using three EVN telescopes (Onsala, Jodrell Bank and Westerbork). Press release.

Recent e-VLBI resultsSteve Parsely has produced a PDF document that describes recent eVLBI results (October 2003). (Also available as a Word document).
EVN e-VLBI roadmapAn EVN roadmap (Diamond et al.) for the implementation of e-VLBI is available, in both PDF and Powerpoint formats.
Workshop on e-VLBIThe second e-VLBI workshop was held on 15-16 May at JIVE, Dwingeloo, NL. Papers presented at this and the previous meeting in Haystack are available on-line.
PoC testsDocuments specific to the PoC tests can be found here.
iGrid2002 demonstrationsDemonstrations of radio astronomy data transfer between the UK and The Netherlands at rates of 500 Mbit/s were held at iGrid2002 and European Research 2002. More information.
e-VLBI funding proposalsSome proposals relating to e-VLBI are available to EVN consortium members. These (together with the previous links) may be useful in formulating (national) proposals for last-mile telescope connections. Electronic (or paper) versions can be obtained by emailing the JIVE secretariat. The titles of the available proposals are:
- vlbiGrid,
- Real-Time VLBI using UKLight Connections to the Netherlands and Global Lambda Research Networks.
- IST Proposal (April 2001, not funded).
