NuSTAR ToO and DDT observation requests will in general not be considered for events or sources that could have been predicted and proposed for in General Observer (GO) programs. This restriction is being adopted as a result of guidance from NASA's 2019 Senior Review.
In particular, requests for observations of the following types of sources and events require special justification describing why the requested observation type could not have been proposed as a GO target:
We encourage the community to propose to the various peer reviewed GO programs for NuSTAR ToO observations. Observations of all selected GO ToO observations automatically have the highest priority for scheduling. |
