I think he means that as a 'long term' thing this happens. I believe
that Superbird has already drifted across the globe many times.

But yes, I expect that people in the Far East will see this soon.
But *when* to look for the flashing? Unfortunately, we don't seem
to understand the geometry of this well enough.

And even if we knew the axis of rotation of Superbird A, wouldn't
it precess? Nutate? Aberrate? Wobble? Whatever. And at what rate?
