Globalstar Flare

I just observed three of the objects from the launch earlier today.  
I believe the first two objects were Globalstar M055 and the Ikar 
(Soyuz R/B (2)).

At about 2:33:30 UT on 23 Sep 99 while waiting for trailing objects
I noticed a brilliant flare to the right.  I suspect it was the 
Globalstar M055.  Magnitude was perhaps in the negative range and
lasted about 5 seconds.

Az/el were around 345/32 with a Skymap phase angle of 76.4.

Could this be another Iridium scenario?

I did watch the same point for about 15 seconds and did not notice
any other flares.  The fact that the first(?) satellite was so bright
while the others were faint or invisisble (in 7x50 binocs) may be a
factor
