Just got in from a great pass here in Phoenix, It was 1x in two parts.
The leader was a bright steady white. The trailer (~5 degrees straight
behind) was a yellow or orange slow tumbler.  ~3 second period going
from dull 1x at the brightest to not seen in 7x50 binos. Satellite
Tracker was showing about 205 km alt for the pass.
