The Swedish Vacuum Solar Telescope (SVST) at La Palma makes high resolution images of the solar photosphere using adaptive optics. This image is taken on April 27 and shows the large sunspot in Active Region 8970.

An interplanetary shock wave from the Sun struck Earth's magnetosphere just before the peak of the Perseid meteor shower on August 12, 2000, triggering a powerful geomagnetic storm. The shock wave originated from a full halo coronal mass ejection that was observed leaving the Sun by the LASCO C3 coronagraph on August 9.

An erupting filament imaged by the Earth-orbiting TRACE satellite on July 19. The filament measures over 100,000 kilometers in height, so that the entire Earth could easily fit into its outstretched arms. Gas in the filament is funneled by the complex and changing magnetic field of the Sun. After lifting off from the Sun's surface, most of the filamentary gas will eventually fall back. More powerful solar eruptions emit particles that reach the Earth and can disrupt manmade satellites.

Geomagnetic storm
In the night of 6 to 7 April 2000, the northern light or aurora was seen throughout all Belgium. The Solar Influences Data Center (Royal Observatory of Belgium) was flooded by telephones and emails from people in Gent, Limburg, Brussels and Liège who saw moving bands in colours varying from red-orange to purple. Good viewing of the event was enhanced by open and clear skies as well as a slender crescent moon.
