I think I recall a side-comment on it as being "shakey". Besides, they 
need to move it out of the way eventually in a decommissioning movement 
so that the slot becomes empty for the next launch. Launched in Aug 1993 
it is to be expected I guess.

They should be up to 31 sats in a couple of weeks. Far beyond the 24 
sats which a "full constellation" needs according to old specs.

Cheers,
Magnus
