Suzaku Guest Observer Facility

Delay of Suzaku AO-10

Dear Suzaku users,

The Announcement of Opportunity (AO) for the Suzaku Guest Observer Program has been released around early September of each year since cycle 2 (2006). As you may know, however, the electric power condition of Suzaku has become severe by degrees, and now the XIS and the HXD can be operated simultaneously only while the solar angle and the orbit both satisfy certain conditions. As a result, it is found that all observations of the targets with priority A and B cannot be completed by the end of March 2015. The operation team has started to consider further reduction of the electric power consumption, in order to increase the period during which contemporaneous XIS and HXD observations can be performed.

In the meantime, the Steering Committee has decided to extend the currently running AO-9 cycle by two months. Accordingly, the next AO (AO-10) is now planned to be released around early November this year, followed by a proposal submission deadline in mid-January 2015.
