| Abstract: | The link between solar flares and
geomagnetic storms is: Solar flare, associated coronal mass ejection (CME)
leading to the subsequent interplanetary CME (ICME) which follows and engulfs
the Earth and its geo-effectiveness due to a large negative Bz component of the
ICME magnetic field B. During the giant flare of 15 February 2011, the last
link, namely a substantial negative Bz, was absent and hence, only a very weak
geomagnetic storm resulted. |
