In general, the solar wind's ability to penetrate into near-Earth space is thought to rely on the magnetic alignment of the interplanetary magnetic fields, often shortened to IMF.

Magnetic reconnection at the Earth's magnetopause is the mechanism by which magnetic fields in different regions - in this case, from the Interplanetary Magnetic Field (IMF) carried by the solar wind, and the Earth's magnetic field - change topology to open magnetospheric field lines.
Specific topics include narrow plasmas streams as a candidate to populate the inner magnetosphere, quick response of the near-earth magnetotail to changes in the interplanetary magnetic field, energetic electron response to magnetic storms, experimental data on the dynamics of the earth's radiation belt, injection of energetic ions during substorms, substorm associated spikes in high energy particle precipitation, and ring current behavior as revealed by energetic proton precipitation.
Like the earlier outburst, which researchers classify as a magnetic cloud, the blob of material ejected on April 7 forced the interplanetary magnetic field around it to point south, allowing it to dump energy efficiently into the oppositely oriented magne tic domain of Earth.
Any space physicist, including me, would have said a year ago there could not be substorms when the interplanetary magnetic field was staying northward, but that's wrong," Lyons said.
For 12 hours, it kept the interplanetary magnetic field near Earth pointing southward, the opposite direction of Earth's own field.
Other spacecraft had failed to make a full portrait of the interplanetary magnetic field because they took only spot measurements in or near the plane in which Earth orbits the sun.
9, it will take pictures of the planet's clouds, measure charged particles in the interplanetary magnetic field and monitor the activity of the sun in what has already proved a record-setting solar cycle.
