The Fifth European Announcement for observations to be performed between April 2010 and March 2011 closed on 20 November at 16:30 CET. A total of 30 proposals were received for the European time corresponding to an over-subscription in time of 3.9. The results are expected to be announced in early March 2010.

Suzaku (previously called Astro-E2) was successfully launched on 2005 July 10 by the Japan Aerospace Exploration Agency (JAXA) in collaboration with U.S. (NASA/GSFC and MIT) and Japanese institutes. Suzaku covers the energy range 0.3-600 keV and is currently performing astronomical observations using imaging CCD cameras (XIS) and a hard X-ray detector (HXD).

Suzaku brings new capabilities to observe all classes of astronomical objects including active galactic nuclei, clusters of galaxies, stars, supernova remnants, X-ray binaries and solar system objects. After a nine month performance verification phase, Suzaku began operating as an observatory, open to the world-wide astronomical community.

Since the start of open time observations, JAXA has kindly offered to allocate 8% of the open observing time to proposals from scientists from institutes located in ESA Member States. The European proposals are peer-reviewed by an ESA-appointed Time Allocation Committee and the recommended proposals forwarded to JAXA for merging with those resulting from the parallel Japanese and US calls.

The Suzaku data archive containing all public data is now open.
