Contrary to my speculation that IGS 1B had lowered its orbit, Russell Eberst
found IGS 1B running 6 to 7 min late last night.

I fit a circular orbit to his two points, then manually adjusted several of
the elements to produce the following search orbit:

IGS 1B           0.0  0.0  0.0  2.9 v
1 70000U          03106.87291759  .00000000  00000-0  00000-0 0    08
2 70000  97.4120 179.0726 0014000 180.0000 238.3995 15.21887238    02

Prediction time uncertainty tonight should be within about 2 minutes.
