We present two-dimensional mapping of a super-Alfvénic (M_A > 1) carbon, laser produced plasma (LPP) as it expands into a preformed, magnetized helium plasma. The formation and propagation of a diamagnetic plasmoid is observed in the ambient plasma that separates a relatively large distance (~0.5 di) from the bulk diamagnetic cavity (~di).
