The 25th version of the IMC, hosted in small and quiet accommodations, was celebrated in conjunction with the 60th anniversary of the organizing NVWS Meteor Section (for which the hosts offered a barbecue, their honorary President’s lecture, and some rounds of live rock music during the last evening). This IMC was again preceeded by a Radio Meteor School and this time also a Meteor Orbit Workshop. One remarkable highlight was the presentation of video observing results and their implications for the IMO’s Working List of Meteor Showers. The excursion allowed the IMC participants to visit the Westerbork Radio Telescopes and the LOFAR prototype station. A very moving moment was a slide-show with information and images from all editions of the IMCs. In the longest night in IMC history, the traditional Saturday evening Astroshow became the Sunday morning Astroshow (with participants from 12 countries).
