1971 A. Barnes et al. in Science 14 May 716/3 It is unlikely that such a region of permanent magnetism (‘magcon’) is unique.
1971 A. Barnes et al. in Science 14 May 717/2 We expect that at some distance from the limb the presence of a magcon is manifested in a hydromagnetic shock wave.
1983 Nature 18 Aug. 589/2 The discovery of small regions of the [Moon's] surface with magnetic fields of 10nT coherent over many 10 km, termed ‘magcons’.
1987 Geophysical Res. Lett. 14 846/2 From the observed angular extents of the magcons (several hundred km), field amplifications by factors of..300 may be expected.
