A coronal mass ejection from October 4 struck Earth the anticpated glancing blow on October 8th, producing moderate geomagnetic storms and aurorae. While that storm is expected to taper off over the next day, a new active region of the Sun is just coming into view. On October 8, a solar flare from that new region erupted on the northeastern edge of the Sun’s disk. More solar fireworks can be expected later in the week.
Below, the Solar Dynamic Observatory’s recording of the extreme ultraviolet solar flare:
