Ion flow speed and magnetic field strength measured by THEMIS D and E. Panel a presents the ion speed at THEMIS D (blue) and THEMIS E (inverted red trace). Vertical dotted red and blue lines are the corresponding onset times measured on higher resolution plots. Panel b is a similar display for the magnitude of the magnetic field. Timing was determined on expanded plots displaying all three field components. Five flow bursts with associated magnetic fluctuations are obvious
