The latest sun storm activity follows a period of flares and mass ejections of coronal plasma that threatened to disrupt power and communications on Earth and in orbit.
Aurora displays occur when charged particles collide with gases in the Earth's atmosphere around the magnetic poles.
We're currently at solar maximum and we're seeing more sunspots. If we see more sunspots, we see this increased frequency in space weather and therefore the aurora.
The forecaster downplayed the chances of a full repeat of last weekend's display, but said more solar activity would mean a good chance of sightings in the coming weeks, months, and years.
