[meteorite-list] Fusion Crusted "Meteoroids"

[Chris Peterson]

The variation in fireball rate with time of year and geographical position 
is well described. Recent observational data is not dependent on direct 
human observations, but can be accurately quantified from instrumental data. 
For instance, I have years worth of nightly allsky records covering 
Colorado, and can produce very accurate information about meteor frequency 
and brightness. This is easily extrapolated to full Earth coverage. And 
there is similar instrumental data from around the world. Actual meteor 
rates are very similar over the entire Earth, with only a very slight 
variation associated with latitude (after allowing for meteors associated 
with showers, which are not completely uniform).
