Writeup from AMN 38(1):
MIL 11149, reclassification.

Mill 11149 was classified as a L6 in the September 2014 (Vol. 37 No. 2) newsletter. Microprobe analyses of this sample have yielded Fa18 olivine and Fs16 pyroxene, indicating that this sample is instead an H chondrite and it is here re-classified as an H5. The magnetic susceptibility also indicates an H chondrite (log χ = 5.32 and 5.34, χ in 10-9 m3/kg).
