Real-time auroral activity

Below you will find the latest solar wind and interplanetary magnetic field data covering the past 24 hours as measured by the Deep Space Climate Observatory (DSCOVR) spacecraft located at the Sun-Earth L1 point. These parameters are the first parameters used to predict auroral activity. The redder the plots get, the better it is for auroral activity! With the current speed, it will take the solar wind 60 minutes to propagate from DSCOVR to Earth.
