Timing between INTEGRAL/SREM SEP events and various source eruption properties near the Sun and at geospace. All correlations are shown as a function of the CMD of the source solar active regions. Shown in the ordinates are (a) the SEP event rise time, (b) the time interval between the flare onset and the SEP event onset, (c) the interval between the projected source CME launch time and the SEP event onset, (d) the interval between the SEP event peak and the shock crossing time at L1, and (e) the interval between the SEP event peak and the onset of the storm sudden commencement. Solid red lines in all plots correspond to the linear least-squares best fits of the shown data points. The details and goodness of these fits (χ ²-statistic) are shown in Table 5. Dotted lines in each plot indicate the solar limbs (east/west for CMD = −90°/90°) and the central meridian (CMD = 0°). The linear and rank order correlation coefficients are also provided for each plot. The outlier in (b) and (c) corresponds to the source-eruption information of event I4 – see text for details.
