The particle and X-ray observations related to event 3 (6 November 1997). Shown here are proton and electron intensities (A, the former multiplied by 10³), the time derivative of the soft X-ray intensity (B) and the soft X-ray intensity (C). The moment of the maximum of dI/dt for X-ray intensity is marked with a vertical red line. The particle intensities have been backshifted in time by (L/v – 500) seconds, where L = 1.20 AU and v = the mean speed of the particle species of interest.
