All the time. Visible mostly in winter because that is when the sky is darkest.
The Aurora Borealis (also known as the northern lights) is seen in the night time sky exclusively in the northern hemisphere. It is more prominently and frequently viewed at northern latitudes, but can be seen generally throughout the temperate regions north of the equator, especially during the equinoxes (near spring and fall). . The Aurora Australis is the southern hemisphere's counterpart to the Aurora Borealis.
From time to time with large CME's from the sun.........the lights can be seen this far down south.
Canada, in the north. (i know you can see them in the Yukon in the spring)
No one can be said to have discovered a natural phenomena that has been known since before recorded time. The Aurora Borealis and the Aurora Australis, sometimes called The Northern and Southern Lights, are natural light displays in the sky, usually observed at night, particularly in the polar regions. Natural phenomena such as the Aurora Borealis have been in existence for millions of years, from times before people existed.

Anytime in winter.
Mostly during winter (skies are darkest then).

One effect is the aurora borealis or Northern lights which are very beautiful this time of year. High electro magnetic activity.
It is caused by the showers of particles spraying out of the sun and captured by the magnetic field of the earth. So it is not actually on a regular schedule, and actually is happening constantly, but is best seen at night. The brightness and extent is determined by how charged the particles are. The closer you are to the north magnetic pole the more often you will see it.

The Aurora Borealis has not been seen in the UK since 2005. However now (2010) we are moving into a time of increased solar storm activity, so there will be more displays of the Northern and Southern Auroras in the next few years. Chances of seeing them in the UK are about 10%. See the video at the attached link
A long time.
I'm not sure if they ever saw it. The only time I know it was seen in Egypt was in 1872. If they did see it, they probably thought it was a sign from Nut, who they believed was the Goddess of the sky.
