[meteorite-list] Ultraviolet Space Rocks?

[MEM]

Off the cuff what jumps to mind is diopside.  It is known in meteorites and it 
is commonly UV reactive..How-some-ever it is yellow in longwave and only blue in 
shortwave.

 I think augite is a longwave yellow fluorescent as well

I'll have to read up on that whole Si2 O6 solid solution series. All those 
pyroxenes are known from meteorites. Many do fluoresce in earth rocks.

Yes I scan all my meteorites for fluorescent flashes.
