Hi Bill,
I captured the 21:12:46 am MST fireball at the very southern edge of the 
field of view. Not much use for location data.

Interestingly, although this particular fireball occurred in the "sweet 
spot" of my forward scatter radio range there was hardly any received 
scatter reflection. Very often with low slow and larger fireballs there 
is only minimal radio reflection.

PS : There was a nice fireball up this way this morning and I posted a 
movie here with its strong radio head echo.
