NuSTAR ToO targets approved within the NuSTAR, Chandra, XMM-Newton, and INTEGRAL Guest Observer programs


    NuSTAR Target of Opportunity (ToO) observations may be proposed for in the NuSTAR, Chandra, XMM-Newton, and INTEGRAL Guest Observer (GO) programs.

    Last update: 2017-07-25

      Proposal title and abstracts are available here, or click on the Proposal number in the table below. Note that NuSTAR ToO and DDT observations may be requested at any time through the ToO/DDT observation request form which provides a list of currently active unanticipated ToO/DDT targets.

      Proposals will be marked with an orange background when they are triggered and a green background when they are completed. Targets that have yet to be identified have blank J2000 coordinates.
