Welcome on SpaceWeatherLive! Below you will find the status of the solar wind and the Interplanetary Magnetic Field (IMF) from the past two hours as measured by the ACE spacecraft. These parameters are the first parameters used to predict auroral activity. The redder the plots get, the better it is for auroral activity! The numbers after the word ''ETA'' on each plot shows how long it will take for the solar wind to propagate from ACE to Earth. The Kp-index is a global indicator of auroral activity on Earth on a scale from 0 to 9. Press the ''Help'' button below each plot for more information! Happy aurora hunting!
This magnetogram gives you the values measured by the ground station of Kiruna (Sweden, Europa). For middle latitude auroral activity the deflection in the magnetometer data should be more than 1300nT.
EPAM stands for the electron, proton and alpha monitoring and is an instrument on the ACE satellite that measures the electrons and protons that are sent with the solar wind. This is a very useful tool whether the CME is directed towards the Earth and when it will happen.

A lot of people come to SpaceWeatherLive to follow the Sun's activity or if there is aurora to be seen, but with more traffic comes higher server costs. Consider a donation if you enjoy SpaceWeatherLive so we can keep the website online!
