    Three Solar Eruptions Combine to Trigger Bright Auroral Show

    magnetic map of the Sun with labels

    From a flash on the Sun to a glimmer in the sky, last week's solar storms illustrated the connection between the Sun and Earth. Three solar eruptions made their journey to Earth, culminating in aurora borealis, or northern lights, visible as far south as Utah. It began with two active regions on the Sun – …

    Solar Eruption Arrives at Earth

    teal colored sun showing solar flare

    A mass of solar material that erupted from the Sun on Oct. 9, 2021, reached Earth on Oct. 12. The Earth-directed coronal mass ejection, or CME, elevated the Kp index, a measure of disturbance to Earth's magnetic field, to 6 (moderate level). Kp index levels range from 0 (quiet) to 9 (intense). The CME was …
