The decay of this Long March rocket has slipped later and westwards much
more than I expected (or, for the sake of US observers, hoped).
The latest elset from OIG ...

... shows it 26 seconds late against the "9122" evolution in my previous
posting on this decay.
My current prediction is for decay at June 7.57 (14h UTC +- 4h). If
this timing is correct, it could drop over the Pacific not far from the
International Date Line.
