A geomagnetic storm with a K-index of 7 or greater is expected, indicating a strong disturbance in the Earth's magnetic field. This event is of interest to sky-watchers because it can lead to spectacular aurora displays at lower latitudes. Sky-watchers should look for possible aurora sightings during this period, particularly near the horizon.
