Hi Wes

This would be either Yaogan 9 or Yaogan 16.  Chinese NOSS triplets, all 
US triplets are no longer in formation.  They're in a fairly high LEO 
orbit hence why they moved slower than the ISS.

Use Heavensat and download the latest Space Track TLEs to confirm which 
one you saw.

BTW - I imaged Yaogan 9 just last night.

Regards,
Scott Tilley

I only got to see them briefly before they winked out.  They appeared to be moving slightly slower than ISS but were not much less bright than Altair, which they were close to.
