Figure 11From: Short-term variability of the Sun-Earth system: an overview of progress made during the CAWSES-II periodSpeed vs. width distributions of limb CMEs from cycles 23 and 24. Both cycles show a good correlation between speed and width, but the slopes are very different. The correlations coefficients (r) and the regression lines are given on the plot. Student’s t-test confirms that the slope difference is statistically significant. The data points at width = 360° are halo CMEs, which are mostly from cycle 24.Back to article page
