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. So the date is the Monday of the week in which the observation is scheduled to begin.

E.g. An observation with a date 2016-11-28 in this table is scheduled to have the observation starting sometime between 2016-11-28 0000Z and 2016-12-05 0000Z.

Currently the schedule is driven by the large number of observations coordinated with other observatories and the need to complete the NuSTAR GO cycle-2 program (N02 in the table, followed by program number). The exposure goal for targets allotted within one week may appear to fill more then the available NuSTAR exposure time in that week (average is 330 ksec per week) but many observations start in one week and complete in the following week.

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.

ToO = Target of Opportunity    DDT = Directors Discretionary Time    N02 = NuSTAR GO cycle-2
X15 = XMM-Newton GO cycle-15    C17 = Chandra GO cycle-17    ELS/GLS = Extragalactic/Galactic legacy surveys
