I don't think that I had heard about the 1859 "once in 500 years" solar superstorm before:
As night was falling across the Americas on Sunday, August 28, 1859, the phantom shapes of the auroras could already be seen overhead. From Maine to the tip of Florida, vivid curtains of light took the skies. Startled Cubans saw the auroras directly overhead; ships’ logs near the equator described crimson lights reaching halfway to the zenith. Many people thought their cities had caught fire. Scientific instruments around the world, patiently recording minute changes in Earth’s magnetism, suddenly shot off scale, and spurious electric currents surged into the world’s telegraph systems.Well, at least it would save me the cost of a long trip from Brisbane to see an aurora. The downside: it's quite possible that it could knock out the electricity grid for weeks:
According to studies by John G. Kappenman of Metatech Corporation, the magnetic storm of May 15, 1921, would have caused a blackout affecting half of North America had it happened today. A much larger storm, like that of 1859, could bring down the entire grid. Other industrial countries are also vulnerable, but North America faces greater danger because of its proximity to the north magnetic pole. Because of the physical damage to transformers, full recovery and replacement of damaged components might take weeks or even months. Kappenman testified to Congress in 2003 that “the ability to provide meaningful emergency aid and response to an impacted population that may be in excess of 100 million people will be a difficult challenge.”This seems a good excuse to see what videos of aurora can be found on Youtube. I want to see real-time video too; usually you see time lapse stuff and it doesn't give you much idea of how quickly the aurora move and change.
Here's a clip which seems to give a good idea of their real time appearance:
