History: A bright fireball with detonations and rumblings was observed by many witnesses. Carl Hergenrother estimated magnitude -11 fireball that created shadows, lasted for at least ~2 seconds moving from the southeast part of the sky to the east and downward. Part of the path was recorded by the All-Sky camera at the UA-Multiple-Mirror Telescope facility on Mt. Hopkins and a security camera in Marana, AZ. Jack L. Schrader interviewed eye-witnesses and recovered the first 155.86 g stone on the surface of the high desert less than 45 hours after the fall. Within a month of its fall, additional stones were found by Chuck Schrader, Shauna Russell, Robert Ward, Todd Parker, and Michael Farmer. Strewnfield occupies an ~3 x 6 km ellipse, trending N 30° E. Coordinates given are approximately at the center of the strewnfield.
Physical characteristics: Total known mass as of July 15, 2009 is 2138.74 g among 10 stones. All except one were recovered as intact individuals with complete fusion crust. Some stones exhibit regmaglypts. Fusion crust is fresh, matte black. One stone exhibits a fusion crust with a reddish hue (not oxidation) and others contain a few "bluish" spots.
