How often are the Northern lights likely to be seen vividly?

The Northern Lights, also known as Aurora Borealis, are most likely to be seen vividly during periods of high solar activity, which typically occurs every 11 years. In regions within the auroral oval, such as Scandinavia and Canada, they can be seen up to 200 nights a year. However, visibility also depends on factors like weather, light pollution, and darkness of the night sky.
