Ez and By disturbances around the reconnection jets from MHD simulation by Birn and Hesse (2014). a Color-coded By in the X–Z plane at t = 132 and y = −1.5 together with the current density vectors (Δj) from Birn and Hesse (2014). Heavy blue and orange contours indicate regions of enhanced tailward and Earthward FACs, respectively. b Color-coded By (normalized to 20 nT) in the Y–Z plane at t = 132 and X = −10. Possible MMS and GOES 14–15 locations relative to the By pattern during the 10:01 UT dipolarization event (Figs. 3, 4) are indicated by arrows. c Color-coded vertical (northward) electric field Ez (normalized to 20 mV/m) in the Y–Z plane at t = 132 and X = −10. d Color-coded By in the Y–Z plane at t = 129 at X = −12. Possible Geotail location during the 10:14 UT dipolarization event is indicated by an arrow. Black arrows in b and d show the E × B drift vectors
