The arc of the first 09023B elset ends with the pass Kevin and I observed; the
second with Brad's pass, one rev later. Rate of decay seems to have been
decreasing, but both arcs are a bit too short to be certain, so perhaps best to
use the one with the higher rate of decay for predictions, to reduce the risk of
missing the object.
