[meteorite-list] Happy B-Day Sikhote-Alin

[Notkin]

Dear Sikhote-Alin:

Happy birthday old friend! Are you really sixty today? You hardly look 
a day over five billion.


Here are a couple of new photos I'd like to share:

Looks like a pretty ordinary piece of shrapnel, right? 1,582 grams.


Well, please take a look at the other side:

Several large, well-formed regmaglypts are clearly visible. As we know, 
the average size of thumbprints on Sikhote-Alin individuals increases 
in proportion to the size of the individual. The size of these 
thumbprints (1 1/2 inches by 3/4) suggests a large mass. I believe this 
to be an exterior fragment from one of the bigger Sikhote masses which 
exploded in flight.

Comments?

And really . . . happy birthday. My collection would be so dull without 
you   : )

And when I have time -- tomorrow hopefully -- will finally get around 
to posting my annual Tucson Show wrap-up.


Regards to all,
