Doing a check on the noss 7 pass, what you saw was the D member of the noss
7 cluster. This is a bad noss cluster to look at. For example at 5:43 UT on
June 15/99, when the D member is at a specific point in the sky, the E
member of noss 7 is at a point in the sky around 20 degrees from where the
D member is. Because of this you won't see all three satellite in the field
of view of your binocular's.
Try the following noss cluster to see three satellite's in a binocular
field of view, I have seen all three at once in a pair of 10*50 binocular's
with a field of view of 5.5 degrees. 

NOSS 2-2 (C)     3.0  2.0  0.0  5.9 v
