The general objective of RadioNet, as an Integrating Activity, is to optimise the use and development of European radio astronomy telescopes with an eye towards future large radio projects, including the next generation of large radio telescopes, the Square Kilometre Array (SKA) and the Atacama Large Millimetre Array (ALMA). A primary goal will be to ensure that European researchers have access to the radio astronomical facilities they need, in order to undertake the key science topics they wish to pursue. Another major goal is to ensure that innovative technical developments in Radio Astronomy are supported on a European-wide basis, pooling the broad range of skills, resources and expertise that exists in Europe. This will provide a critical mass that will ensure that progress is not made slowly in isolation but quickly and efficiently, via a broad-based, yet well-focussed, scientific and engineering collaboration.

RadioNet FP7 has grown, now involving 26 partners from 13 different countries, contributing effort to 18 independent work packages. These include joint research activities, training for undergraduates and post-graduates, workshops targeted towards new and emerging topics of research and last but not least, enabling scientists to obtain easy access to Europe's largest and most sensitive radio telescopes.

In addition to member states, other countries participating are South Korea, the United States of America and South Africa. The RadioNet management plan builds on the close collaboration that many of the institutes have developed over the last 30 years of joint participation in the European VLBI Network (EVN) - an array of 16 major radio telescopes spanning Europe and other major regions of the world, in particular China and South Africa. The many threads of RadioNet come together in the Netherlands institute for radio astronomy, ASTRON, under the leadership of Professor Michael Garrett who is the RadioNet Coordinator.

The RadioNet web-site continues to be the main interface between RadioNet and the astronomy community.

ASTRON is part of the Netherlands organisation for Scientific Research (NWO).

Another great achievement by @ehtelescope! Our new director @astroTui was involved as well, as a member of the #EHT team.

Every year on 4 May at 8 pm, our Westerbork telescope goes into a special mourning position to commemorate those who have fought for our freedom. This video, made together with @kampwesterbork, shows the dishes moving into position.

Our 'holy grail' has been found again! The #Kootwijk dish, which stood at the origin of ASTRON, has been located at @museumdeelen! The dish, originally a #Würzburg-Riese German radar dish, was the second telescope ever to detect the #hydrogen line.

Issue 10 of @SKAO's Contact Magazine has been published, featuring 3 articles related to ASTRON: 1 about our new director @astroTui, 1 about @LOFAR's massive data release, and 1 by our own @tammojan about @LOFAR imaging radio emissions of meteor showers.
