Space weather
By Storm Dunlop
We are all used to blaming things (rightly or wrongly) on the weather, but now it seems that this tendency has been extended to space weather. Space weather, for those who are uncertain, describes the effects that flares and other events on the Sun produce on Earth. Consult many of the sites on the World Wide Web that are devoted to events on a particular day in history, and you will be told that on 16 August 1989, a geomagnetic storm caused the Toronto Stock Exchange to crash.
