What's up July 6?

In the last week NuSTAR has been performing a series of alignment measurements  - pointing all over the sky at different bright X-ray sources to check the alignment of the spacecraft and telescope systems.  This will take through the weekend.   Next week these data will be used to possibly update the telescope alignment again, after which point spread function calibrations will begin.

All systems remain nominal.
