A plot of interplanetary magnetic field parameters from 19 to 22 November 2003. From top to bottom are plotted the magnetic field strength (B), the elevation (θ) and azimuth (ϕ) of the magnetic field direction, three-dimensional magnetic field components (B_x, B_y, B_z), plasma beta obtained from Wind spacecraft and 1-h averaged Dst index. Red line indicates the shock while the region between blue lines is magnetic cloud. Time is plotted in hours starting from 19 November, 00:00 h.
