[meteorite-list] Temperature of meteorites (Bernd's List)

[Chris Peterson]

A dark crust certainly will absorb energy from the Sun during the fall. But 
that radiative energy gain is going to be a lot smaller than the convective 
loss from a stream of -40° air blowing across the stone at 100 m/s or so!

I'd think a smooth fusion crust would actually provide better heat transfer 
than a rougher surface.
