AB: A record of magnetic holes observed by the WIND satellite in the solar wind from 1994 to 2004 was recently compiled. When permitted by the relative positions of the two satellites, ACE observed many of the same magnetic holes. By comparing the shape and plasma parameters at each satellite, the geometry and propagation of the holes are constained. The coherence of each hole and the associated pressure balance also help us to distinguish the sources of magnetic holes in the ecliptic and discern possible MHD solitons.
