From the MetBul:
At 21:07 local time on 23 April 2019, a meteorite fall was reported
in Aguas Zarcas, San Carlos county, Alajuela province, Costa Rica. The fireball traveled WNW to ESE and was caught
on cameras of the National Seismological Network (RSN) at the summit of Poás and Turrialba volcanoes, and from the Volcanological and Seismological Observatory of Costa
Rica (OVSICORI).
Stones under ~50 g are typically angular to blocky and lack regmaglypts. Also found were several plate-like, oriented stones. For example, one oriented
plate is 13 cm wide and 1 cm thick. Many stones are oriented with a domed leading edge and well-developed roll-over lip along the rim of the trailing edge. Larger stones,
especially those near 1 kg, show broad regmaglypts, some well developed. The fusion crust on several of the trailing edge surfaces is iridescent.
Pre-rain material crushed
in a few ml of water emits a powerful "Murchison-like" odor, though with a more prominent compost-like scent.

This is a beautiful example of some unique flight marking that you can only imagine glowing incandescent! ...reminded me of "The Doomsday Machine", a Star Trek episode about a similarly shaped rock that ate starships if they were caught in the gravitational force going into its "mouth" end... |

yes Bernd, in photo #3 we are looking at the rimmed tail of a "bullet/slug" shaped oriented stone...with the nosecone pushed into the orange putty. |

Fabrice, that's a beautiful, fully crusted Aguas Zarcas individual. Photo #3 is especially interesting! |
