XMM-Newton Target of Opportunity (ToO)

ToO Policies & Procedures

Targets of Opportunity (ToOs) are subject to the policies and procedures explained in the XMM-Newton Policies & Procedures Document which is available online (or can be downloaded from here).
Please, pay particular attention to Section 5.2.2 and especially Subsection 5.2.2.2, which makes reference to unanticipated ToO alerts explaining also the policy for the determination of proprietary periods of such observations.

"Discretionary Time” may be granted for programmes where a timely observation (outside of the normal announcement of opportunity cycle) is likely to result in a significant scientific impact.

ToO Alert

Investigators may notify the XMM-Newton SOC of a Target of Opportunity online. Simply complete the details on the ToO Notification Page.

Pending Anticipated ToOs

A list of anticipated ToO observations already accepted by the XMM-Newton Observing Time Allocation Committee (OTAC), which are currently not yet fulfilled, is available at this link.

Unanticipated ToO Details

The following list comprises approved and performed unanticipated ToOs.

The status of the data is denoted using the following acronyms:

The links from entries in this table are as follows:

This table is weekly updated, but there might be periods for which updates take slightly longer. Should you need to know details about a ToO/DPS observation, that are not given below (yet), please do not hesitate to contact the HelpDesk.
