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 :)

131.8 grams. CV3 TKW 2 tons. Observed fall 8 February 1969, at the village of Pueblito de Allende, Chihuahua, Mexico. Steve writes:Allende is a well-known meteorite with a number of very nice MPOD submissions. Having fallen the same year but earlier than Murchison, its timing was perfect to use as a dry run for the Apollo Lunar Receiving Lab prior to the Apollo 11 moon landing and subsequent return of lunar samples. And under high magnification, structures have been seen in some Allende samples that terrestrially are evidence of fossilized nanobacteria and their byproducts. There is so much more interesting information on Allende that even my typically lengthy write-ups on famous meteorites would barely scratch the surface, so instead I'll simply make a few comments on today's photos. A few years ago Bob Falls offered some particularly large slices of Allende (two have already been featured on MPOD). I chose the 131.8 gram slice in Photos 1 and 2 because of some interesting inclusions seen in only some of Bob's slices. Photos 3 and 4 offer close-ups of a few of these: the ones in Photo 3 all exhibit a greenish cast, while the rightmost image in Photo 4 has a distinct pinkish color. Photo 5 is an enlargement of a typical chondrule-rich area.
