Writeup from MN J20:
Y981956 and Y002875
Diogenite

These sections are similar to Y981247 and Y981582 in mineral chemistry and texture. Thus, these meteorites are paired. The sections show an aggregate of very fine-grained needles and wedges of orthopyroxene which are broadly aligned. Miner minerals include Fe-metal and troilite. Pyroxene compositions are Wo1.9-2.2Fs22.9-25.1, and wt Fe/MnO = ~31. These meteorites are unbrecciated diogenites.
