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 :)

Light gray with a few chondrules and reflective metal flecks.
From Mindat.org:
Without a fireball, but with loud sounds and a final blast, an oriented meteoritical stone with most of its fusion crust arrived in present-day Dobele, Latvia late in the afternoon. Dug out from the ground a day later, the meteorite appears to be a somewhat typical ordinary H5 chondrite with moderately well-equilibrated olivine (Fa19) and lesser pyroxene conspicuous in chondrules, crystals, and small fragments. Diverse chondrules, mostly porphyritic and radial, are partially equilibrated with the matrix, but glass and other dark inclusions are also present in matrix and chondrules. Pyroxene is mostly orthopyroxene but twinned Ca-poor clinopyroxene and even some Ca-rich diallage are present. Accessory and/or minor Fe-Ni metal, troilite, and plagioclase are found as well.
In the 19th Century, 4 ordinary chondrite falls were recovered in Latvia [Lixna (1820), Buschhof (1863), Nerft (1864) and, finally, Misshof (1890). Curiously enough, these four are the only meteorites recovered from Latvia. As the new millennium began approximately half of the original Misshof mass (2.5 kg) was still held at the Riga Technical University. |

Very interesting that all of the Latvian meteorites were all found in the same century, and no more have been found in the last 131 years! Makes one wonder how many are still waiting to be discovered! |
