[meteorite-list] Observed lunar meteorite impacts (distribution)

[Piper R.W. Hollier]

Dear Mark and list,

For me the distribution of impact sites shown on the second image "A 
map of the 100 explosions observed since late 2005" runs counter to 
my intuition. Why is the distribution not more uniform? There are 
large areas, especially near the poles, with no impacts recorded, 
while other areas have rather dense clustering of impact 
observations. Comets often have highly inclined orbits, so it seems 
that we should expect some impacts near the poles.

Any ideas out there?
