Cold Cores - Besancon, June 4-7 2018

The 9th meeting of the Planck and Herschel project on Cold Cores will be held in Besançon between the 4th and the 7th of June 2018. The days will consist of normal presentations and of discussion sessions on observing projects and ongoing studies.

Practical information

Some advice to reach Besançon and the observatory can be found here. We provide here additional information for people travelling by plane. Note that the closest airports are in Basel, Lyon, Strasbourg and Paris, and that they are connected to Besançon mainly by train (2 - 3h) or car (for Basel, <2h).

• Through Basel: If several people arrive the same day at the airport of Basel, we can organise a pick-up by car to travel from the airport to Besançon in less than two hours. Please contact Julien to organise it. Alternatively, a bus shuttle connects the airport to the train station named "Saint-Louis" (ligne11.pdf), where regular SNCF trains can be caught to reach Besançon.
• Through Lyon: The Lyon Saint-Exupéry airport is well connected to the main train station (Lyon Part-Dieu) thanks to the train shuttle RhoneExpress (see here). Once in Lyon Part-Dieu, there are several direct trains to Besançon Viotte (city centre) and/or Besançon Franche-Comté TGV (16km from the centre).
• Through Paris: If you land in Paris Charles de Gaulle, there is a direct train between the airport and Besançon leaving CDG at 19:58, and a direct train to the airport leaving Besançon at 6:29. The alternative is to use the Paris public transports to go the "Gare de Lyon" train station using RER B + Metro 14. There are many trains between Paris Gare de Lyon and Besançon.
• Through Strasbourg: The airport is very well connected to the main train station by a train shuttle (see here), where regular SNCF trains can be caught to reach Besançon.

Social program

Classical, baroque music addicts may enjoy the Four Seasons by Vivaldi played by the Opera of Prague at the Cathédrale Saint-Jean on Monday 4th. Tickets can be purchased for example here.
