Re: Warning for odd TLE

I'll note that the mean motion (*not* mean anomaly) of 0.0347 is correct
for this object. It was 0.04 but
further lunisolar perturbations have  lowered the mean motion even further.
So it's worth making clear that the issue is a limitation of the software,
not an error in the TLEs.
