Lighting conditions for the Soyuz descent suggest that the sun-lit
Soyuz, and its separated three modules, may be visible from the
dark ground by observers near its ground track shown in the following
link. Actual fireball views may only appear late in the track, over the
Black Sea.

It should be preceding the ISS itself through the sky.

If you know anybody in this area, pass the word
for a possible pre-dawn sky spectacular.
