  ... what percentage (if any) of these faint telescopic meteors on any 
given clear, moonless night at a dark sky location, would be low (or 
any) orbit mini satellites? - how fast would they whiz through a 6 or 
2.3 d binocular fov? as fast as a faint meteor? - often thought that 
some of them must be satellites I guess - I did read somewhere there 
are thousands up there?.

Observers of all kinds sometimes *appear* to me to be very thin on the 
ground in the Southern.H  ;-)
- just a population thing I suppose?

  I did have planetarium chart printouts with me, and meant to do proper 
obs. - I even had my talking clock for its first outing! - but the 
comets won out on the morning.
