Aurora Forecast
Tonight's outlook
January 13: Activity decreases as Earth exits high speed solar wind from a coronal hole. Fine aurora likely tonight if Bz stays south. Ignore the Kp-index forecasts but watch the Bz value under Real Time Space Weather Data below. When south for an extended period of time (~30 mins), aurora intensifies even if activity is low. If north, aurora is weak. Follow us on Instagram for latest updates. Support us with buymeacoffee.com
