My estimate last night as pair passed 5 deg under (SE) of Vega in medium twilite was -2.5, using Jupiter and Vega as comparison stars and naked eye. This was approximately the maximum illumination vs. range point for that pass. With bright objects it is said catch them in twilite if possible. Through 10x50 binoculars, the pair illuminated the thin cirrus with a halo that was similar to Jupiter's, also.

A pretty sight. Closest approach was at 02:23:17 UTC. The altitude was 25 degrees. Has anyone attempted to determine the combined magnitude of the pair? I see that H-A lists the magnitude of the ISS alone.
