On August 24 -26, 2011 the Department of Astrophysics of the Radboud University honours the 65th Solar revolution of Jan Kuijpers with a symposium, to be held in Nijmegen: Magnetic Fields and the Cosmos. On Friday afternoon (August 26) Jan Kuijpers himself will also give his public retirement lecture at the main auditorium of the Radboud University.

The Jan65 symposium will cover many of the topics that Jan has worked on in his scientific career and the main research topics that are pursued at the Radboud University's Department of Astrophysics, which was founded by Jan Kuijpers exactly 10 years ago.

We have made a block reservation at two hotels in Nijmegen:

Please contact these hotels directly for reservations and make sure to mention the 'Astronomy/Sterrenkunde' reservation. Both hotels are located in the inner city of Nijmegen. The Mercure hotel is close to the train station and the Belvoir is closer to Waal riverside. Note that the block bookings are in place until mid-July

Transport from Schiphol Amsterdam Airport

Schiphol Amsterdam Airport (airport code AMS) is the most conveniently located major airport. After arriving at Schiphol airport the easiest way to travel to Nijmegen is to take the train (company called NS). Between 07:00 and 21:00 direct trains leave from Schiphol to Nijmegen every half an hour at XX:29 and XX:59. Nijmegen is the terminal stop of this train. Between 04:00 and 07:00 and between 21:00 and 23:14 Nijmegen can be reached from Schiphol by first taking the train to Utrecht Central Station and change in Utrecht for the train to Nijmegen (other side of the platform). For more information visit the NS website.
