(meteorobs) RE:Super-Meteor' Lights up Finland's Northern Sky

Thomas I suspect there is a good chance slow fireball may be generating so 
much ionization that it has a progressively densor regions around it.  i.e., 
not reasonably uniform in charge.

This may cause partial ABSORPTION rather than reflection of radio waves.

Or another possibility is that a non linear distribution of ions may in fact 
re-bend the incident RF signal path much like the Ionosphere routinely can 
have several angular reflections within the Ionosphere, BEFORE the "skip 
distance wave" radiates down to a receiver.

Ionospheric refraction is entirely possible here for Fireballs.
