Northern lights can be viewed by millions in US, Canada, and the UK this weekend.
What causes northern lights? Are they harmful?
On March 20, a solar flare erupted which is scheduled to hit Earth this Friday night. In light of this, the National Oceanic and Atmospheric Administration issued an alert to be on a lookout for a geostorm of moderate intensity (a.k.a G2).
This solar flare will end up supercharging the northern lights, pushing it deeper and making it visible for millions in the US, UK, and Canada.
Fret not though, apart from an extremely limited blackout of high-frequency radio signals and disrupted navigational signals, the northern lights are totally safe and do not harm you or your electronics in any way.

What time do the northern lights start?
The northern lights don’t have a “start time” per se, they will be visible as soon as the sun sets down and the sky is dark. However, experts recommend that the northern lights are seen best when it’s 3-4 hours before midnight.
