| Abstract: | In March 1989 a large and complex spot group, active region 5395, rotated across the visible disk of the Sun, thereby creating a number of big solar flares and bright coronal mass ejections (CMEs). Feynman and Hundhausen (1994) investigated the association of both proxies of solar activity. For a classification of the flares they used the H importance and the GOES soft X-ray data. To get a more consistent picture of the importance of the flares selected, we contribute the 2.2 MeV neutron-capture line fluence, recorded by the gamma-ray spectrometer on SMM, as a measure of nucleonic interactions. By considering these data, we confirm the Feyman and Hundhausen conclusion that neither the flare directly causes the CME, nor is directly caused by it. |
