Winner        43.3637137, -99.9197665

Tripp County, South Dakota, USA

Found: Aug 2004

Classification: Ordinary chondrite (L3.9)

History: In August 2004, Chris Novotney was getting off his tractor to unhook a hay rake and get gas when he noticed a rusty rock, which he collected: it was eventually identified as a meteorite. The rock stayed in the possession of Mr. Novotney until he sold it to KD Meteorites in 2013.

Physical characteristics: Single stone, exterior partially covered by dark weathered fusion crust, some oxidation, saw cut reveals numerous chondrules and clasts of variable size and color (white, green, and gray), some up to several mm, medium grained metal/sulfide throughout.

Petrography: (C. Agee, UNM) Microprobe examination of a probe mount shows many well-defined porphyritic and BO chondrules, with coarsely recrystallized mesostasis and plagioclase. Ubiquitous kamacite, taenite, troilite, and chromite. Some iron-oxide veinlets.

Geochemistry: (C. Agee and N. Muttik, UNM) Olivine Fa26.0±2.7, Fe/Mn=50±6, n=10; orthopyroxene Fs21.7±0.8Wo1.4±0.2, Fe/Mn=30±2, n=5, clinopyroxene Fs10.1±1.8Wo44.3±1.0, Fe/Mn=29±1, n=2.

Classification: Ordinary chondrite (L3.9), weathering grade W2.

Specimens: 32.1 g including a probe mount on deposit at UNM, the finder Chris Novotney holds 20 g, ASU holds 7.8 g, KD Meteorites holds the main mass.
