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 51 minutes to propagate from DSCOVR to Earth.
Note that you can zoom in on these plots by selecting a time period that you wish to view and even export them as JPG, PNG, PDF or SVG files. Beneath the plots you will find help buttons that will bring you to our detailed help articles and a dropdown menu to plots with data from the Advanced Composition Explorer (ACE) and the Solar and Heliospheric Observatory (SOHO) satellites which might be of use if there are issues with the data from DSCOVR.

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!
