15 604B is NOSS 3-4 r #31702
I had seen it before somehow, perhaps in SeeSatVB.
HeavenSat DID show it in "Stars Approaches" despite the 70<i<125 filter
being set there as well, and displayed the track when clicked.
In "Passes" it WAS predicted, but refuced to show the track, without
showing the cause.
