Observing schedules

Short Range Observatory Schedule    

This is the confirmed schedule of NuSTAR observations. This sequence of observations has been uploaded to the spacecraft and will execute autonomously unless interrupted by a new schedule, Target of Opportunity, or instrument and spacecraft anomalies. This schedule will cover various time ranges depending on the exposure time goal of the observations, but will usually be for a period of at least one week.

The times reported here are the start and end of the on-target period (day of year UTC). The estimated exposure time takes into account Earth occultation and the SAA passage time where detector background is increased. The end time of the observation is the start of the slew to the next target. Please examine the As-Flown Timeline (AFT) for the log of past observations.

Long Range Observatory Schedule    

This is the latest NuSTAR long-term schedule. Observations have been sorted into one-week intervals, taking into account Sun, Moon, required exposure time, and other constraints. Currently the schedule is driven by the large number of observations coordinated with other observatories and the need to complete the scientific level 1 project requirements. Targets which are not constrained do not appear in this table. The exposure goal for targets allotted within one week may appear to fill more then the available time in that week (~330 ksec) but many observations start in one week and complete in the following week. For coordinated observations the scheduled week is the earliest possible week for the observation which may have a window of many months to complete.

Targets of opportunity and any instrument or spacecraft anomalies may also cause the observing times of targets to shift. This long-term schedule is our present estimate of the future order of observations. Please be aware of the uncertainties.
