      "Extreme value statistics in the solar wind"


The solar wind is a turbulent plasma streaming from the sun 
at a speed of the order of 10^5 metres per second. Its 
interaction with the Earth's magnetic field is responsible 
for the aurorae. On rare occasions it may also damage 
satellites, threaten astronaut safety, or lead to power 
blackouts as a result of intense geomagnetic storms. A 
measure of the solar wind's power input into the Earth's 
magnetosphere is given by the Akasofu epsilon parameter. In this 
talk I analyse the time series of the epsilon parameter for extreme 
bursts during the years 2000-2008. This analysis will include 
not just the distribution of sizes of extreme bursts, but 
also their return time statistics.
