Re: Neo Search and satellite imaging

Excuse my ignorance about NEOs, but I wonder:

Are NEOs only near-circular, near-ecliptic (near-equatorial!!) and
posigrade (ie usually slow)?
And are other asteroids of no interest in these images ?

Are exposure times so long that most satellites show light curves
"impossible" for NEOs ?

If not, how can you rule out a track as being a satellite (not a fast
passer at lunar distance etc.) without measuring it ?

If you do measure them without analysing, why not post them (with a
suitable fixed heading) to SeeSat-L for amateur analysis ?
