Targets of Opportunity
The ToO policy is being updated for the NuSTAR Guest Observer program and will be updated on this page in mid-September 2014.
Please check back for more information soon.
The requirement on ToO response is <48 hours from the time that the P.I. decides to undertake a ToO observation to the time that NuSTAR has slewed over to the new target and begun integrations. Typical response times are expected to be <24 hours. ToO observations with longer lead times are less intensive for the operations team.
Currently, outside suggestions for ToO observations will be considered for truly exceptional opportunities. However, the limited operations team makes it unlikely many ToOs can be accepted during the initial 2-year baseline mission. Such requests, limited to 250 words and including the target coordinates, should be sent to the NuSTAR Principal Investigator, Fiona Harrison, with cc: to the NuSTAR Project Scientist, Daniel Stern.
