2021 Fall Date Project

The MPOD Caretakers want to present meteorite falls on their fall dates. For example, Sikhote Aline on 12 February.

This Project will not dip into the MPOD archives so the Caretakers will appreciate anything you can contribute.

To reserve a date just let us know. Thank you in advance :)

Individual with flight orientation and with one large cavity of (approx.) 125 x 80 x 55 mm.

Due to the heavy weight I call it 'Little Asteriod'.

Distinct regmaglypts. I received it in dirty condition. After soft cleaning with a hand wire brush I found some crust conserved in deeper regmaglypts :-).

In my collection since 1994 .

The cleaning result was/is perfect and without any damage to the desert patina or to the three remanents of fusion crust. I have never used electrolitic cleaning and I think electrolitic cleaning make only sense, if you want to clean unstable iron meteorites with strong tendency to rust.
