XMM-Newton AO-8

The XMM-Newton eighth Announcement of Opportunity (AO-8) closed on
the 10th of October 2008.

In total, 555 valid proposals were submitted requesting in total
107800 ks of science time. This Announcement of Opportunity covers a
period of one year with 14500 ks of observing time available for
distribution. The over-subscription factor is 7.4.

In total 51 proposals for "Large Programs" were submitted.
Triggered/TOO observations are requested in 33 proposals. For the
joint XMM-Newton Chandra program the SOC received 10 proposals and
for the joint XMM-Newton ESO (VLT and VLTI) program 5 proposals are

SOC received proposals from 397 different principal investigators
from 25 countries, mostly ESA member states, the United States and
Japan. The number of countries involved increases to 40 if
co-investigators are taken into account as well. Considering
principal investigators and co-investigators, about 1430 individual
scientists were involved in the response to the eighth Announcement
of Opportunity.

XMM-Newton SOC temporary unavailability (no ToO service)

The XMM-Newton Science Operations Centre will be unavailable
starting on Friday October 17th (afternoon) and possibly for
the whole of the weekend (October 18th and 19th) due to a
scheduled power outage at ESAC. During this period, the
website will be down and the Target of Opportunity alert
service will be exceptionally interrupted. We regret any
inconvenience caused by this unavoidable maintenance activity.

Yours sincerely,
XMM-Newton SOC
