DADI-CLEOPATRA meeting on the Time Domain

A meeting gathering DADI and CLEOPATRA staff is organised to discuss topics of common interest in the time domain. The time domain is one of the initial DADI priorities, and DADI is involved in particular in gathering requirements for the evolution of the VOEvent IVOA standard. One of CLEOPATRA tasks is to “develop methods for relaying alerts, which will signal transient event detections between the facilities and enable joint observing programmes. The focus will not just be on interchange formats but on scientific strategies and methods for joint observing.” Contact persons: Françoise Genova (DADI), Mark Kettenis (CLEOPATRA)

Meeting: 21 March 2017

The meeting is organised the day before the Third ASTERICS DADI Technology Forum.

Observatoire astronomique de Strasbourg, 11 rue de l'Université, Strasbourg, FRANCE
Access Information

The meeting will be held in the main building with the big dome.

Please arrange your own hotel accommodation. Strasbourg has a lot to offer, and hotels in the central part of town are generally accessible by foot or tram.
