The Current Solar Wind Speed
The Solar Wind Speed is measured in km/per second .Over 800 km/s indicates strong auroral activity probability .500 km/s or less indicates possible activity or weak activity. Zero - 300 km/s very weak activity with minor observations at the locations very near to the poles.
