Macroscopic Description: Cecilia Satterwhite
The exterior of this meteorite is brown. The interior revealed a brown matrix with no obvious features.

Thin Section (,2) Description: Tim McCoy, Cari Corrigan
The section consists dominantly of a fine-grained melt-textured matrix of olivine and pyroxene (1-10 microns) with irregular blebs of metal with rimming sulfide and fragments of mineral grains (200-300 micron grain size.) The mineral compositions are homogenous; olivine is Fa18 and orthopyroxene is Fs16. The meteorite is an impact melt of an H chondrite precursor.
