Phase 1 of the cancellation process. (a) Two photospheric magnetic sources of flux ±F, situated on the z-axis a distance 2d apart in an overlying uniform horizontal field approach one another at speed ±v0. (b) When d = d0, a separator S is formed. (c) Reconnection is driven at the separator S which rises in the atmosphere. (d) Energy is converted at a current sheet of length L, where plasma flows in at speed vi carrying magnetic field Bi.
