The solar flare and coronal mass ejection(CME) events associated with the large and complex March 1989 active region are discusses. This acative region gave us a chance to study the relation of CME with truly major solar flares.
The adequacy of the power spectrum to characterize the variations of a parameter depends on whether or not the parameter has a Gaussian distribution. We here perform very simple tests of Gaussianit on the distributions of the magnitudes of the interplanetary magnetic field, and on the distributions of the componentsi.e. we find the first four cumulants of the distributions (mean, variance, skewness and kurtosis).
