Hi Darryl,

Regardless of whether Lovina is a meteorite or not, it is a
fascinating specimen. Possibly the most interesting meteorwrong (if
that is the case) since Shirokovsky.

To me, some meteorwrongs are intriguing and my curiousity compels me
to acquire a piece and/or learn all I can about them. Every now and
then, I take out my slice of Shiro just to admire it and hold it up
the light to admire the translucent crystals. Mendota is another
example of a strange wrong that is uniquely interesting. In the cases
of Mendota and Shiro, nobody can explain exactly what they are or how
they were created. Scientists have analyzed both, and the best answer
is - "it is not a meteorite". Ok, then what is it? That makes for a
specimen worth acquiring, in my opinion. But, I am a rockhound in an
addition to a meteorite collector, so maybe it's just me.

I look forward to reading the new abstract on Lovina.

Best regards,

MikeG
