The booster must have skipped up again, they showed a decsent
trajectory of the South Indian Ocean but how its regained altitude from 146 km back up to 328 km now just 100o miles off the East coast of Japan.
We have a skipper. If it goes down on the next low in its orbit, it will be a lot closer to Australia.
Look out Fred!

Its actual altitude goes from high to low and then back each orbit.
