Kp 3-4
Active
Bright auroras visible to the naked eye. Green colors become obvious. Good displays at zenith in Nordic countries.
Kp 5-6
Storm
Vibrant, dynamic displays with multiple colors. Red and purple hues appear. Aurora coronae likely. Memorable experiences.
Kp 7-9
Severe Storm
Exceptional displays visible at mid-latitudes (40-50°). Intense colors, rapid movement. Rare and spectacular events.
