Bjrn Gimle discussed the possibility that a Belgian observation mentioned by 
Tristan Cools (May 30, around 02:01 UTC) could be the decay of 1989-096A  GRANAT.
My calculations based on the last released ELSET 99141.750... and the NORAD
MSGP4 - model shows the perigee pass on   May 29, 23:46 UTC (15.3N,  53.3E)
over the Gulf of Aden /Yemen / Saudi Arabia. I think this is too early to explain 
the Belgian observation (I haven't seen any details here).

The next perigee -tonight UTC -  is   June 3, 02:03 UTC  (14.7N, 14.3E) over 
Central Africa, maybe the final pass of GRANAT. 

But MPM shows a realistic possibility that GRANAT can survive the June 03 perigee 
and will be decay on     June 7, 04:23 UTC (17.8N, 338.3E)    over the African
Atlantic coast.
