A close-up of the Sutter's Mill Meteorite, a fragment from a daytime fireball that exploded over parts of California and Nevada on April 22, 2012. This fragment was discovered in a horse pasture in outside of Lotus, Calif.
The red bullseye indicates the location where a meteor exploded over California's Central Valley on April 22, 2012. The yellow triangles mark infrasound arrays, which were key in determining the location of the meteor's explosion.
Fragments of the Sutter’s Mill meteorite fall collected by NASA Ames and SETI Institute meteor astronomer Dr. Peter Jenniskens in the evening of Tuesday April 24, two days after the fall. This was the second recovered find.

Peter Jenniskens, a meteor astronomer with the SETI Institute, describes the features of the Sutter's Mill Meteorite to a team of volunteers who helped find it in a horse pasture outside of Lotus, Calif. The meteorite is from a fireball that exploded over the region on April 22, 2012. Jenniskens led the search for the NASA Lunar Science Institute.
The de Haas family of Lotus, Calif., donated the Sutter's Mill Meteorite to NASA for further study. The meteor is a fragment from a fireball over California and Nevada on April 22, 2012.
This map shows where the fireball likely broke apart over California, according to signals captured using very low frequency sound.
