Since it is not attitude controlled like Iridium, that is no good analogy.

Mathematically, the possible flash locations could be predicted like we do
for Superbird A, ETS-6 and a few more satellites.

But practically it is impossible, because we would need hundreds of accurate
flash positions to determine the axis, and it would only be valid for a
short time, because of eddy currents and atmospheric interaction at their
low orbital heights.
