Unfortenately, this object wasn't observed for about 50 days, but
it is clear that during the last two months the period remained 
nearly constant, so the acceleration has slowed down considerably or 
maybe it is even going up again !?!
It is still visible over Europe for the next two weeks and is flashing
at about mag +5 (at 36000 km !)

Period is still nicely going down.
