Upward (red) and downward (blue) integrated currents in the midnight-morning sector (east of 23 MLT) and evening sector (west of 23 MLT) throughout the interval around the substorm onset time (edge of gray area) at 20:37 UT January 15, 2010. Green lines mark the difference in net FAC in each sector, inferred to be the cross-meridian current, and black dots show this quantity based on AFM
