  The ~200 m/s impact of a single 400-kg Bjurb\"ole L/LL ordinary chondrite
meteorite onto sea ice resulted in the catastrophic disruption of the
projectile. This resulted in a significant fraction of decimeter-sized
fragments that exhibit power law cumulative size and mass distributions. This
size range is underrepresented in impact experiments and asteroid boulder
studies. The Bjurb\"ole projectile fragments share similarities in shape
(sphericity, and roughness at small and large scale) with asteroid boulders.
However, the mean aspect ratio (3D measurement) and apparent aspect ratio (2D
measurement) of Bjurb\"ole fragment is 0.83 and 0.77, respectively, indicating
that Bjurb\"ole fragments are more equidimensional compared to both fragments
produced in smaller scale impact experiments and asteroid boulders. These
differences may be attributed either to the fragment source (projectile vs.
target), to the high porosity and low strength of Bjurb\"ole, to the lower
impact velocity compared with typical asteroid collision velocities, or
potentially to fragment erosion during sea sediment penetration or cleaning.
