| Abstract | From March 5 to 19, 1989, sunspot region 5395 crossed the Sun's disk and was the source of numerous X-class and M-class flares. Coronal mass ejections associated with these flares hit the Earth on March
13 resulting in the now-famous impacts in technology on Earth. Solar and solar wind observations at the time were limited which has made it difficult to assess exactly what happened during this event. This presentation reviews the available evidence
for this period, some of which has only come to light since that time. This provides a reconstruction of the chain of events from coronal mass ejections to their interaction with the Earth's magnetic field, and the resulting disturbances to power
systems in different parts of the world. Lessons learned from this contribute to under-standing the space weather hazards to power systems and other critical infrastructure. |
