Fig. 11

Ground and space magnetic fields at the time near an impulsive event on February 17, 2015. The bottom panels show the three components (B _X in black, B _Y in red, B _Z in blue) of baselined data for AUTUMNX stations RADI and INUK, and NRCan station SNKQ relative to the starting value of the day. The second from top panel shows GOES 13 data in the same manner as Fig. 10 except that the total field has been added in green. The top panel shows the propagated (see text) solar wind magnetic field in GSE coordinates (B _X black, B _Y red, B _Z blue), with total field in green
