How long does the Aurora Borealis last?

Answer 1

Usually about 1 hour to 2 hours. A very faint Aurora lasts only a few minutes. Some auroras which are very strong, a.k.a. "aurora storms" last for days, fading away and returning. It all depends on our sun's activity.

Answer 2

It depends on many factors, but mainly on how close you are to one of the Earth's magnetic poles (the north magnetic pole is in the eastern Canadian arctic) and where we are in the 11 year cycle of solar activity. At present we are just past solar minimum, so there's relatively little aurora activity anywhere, but it's starting to pick up. There's no way of predicting it exactly.

[edit] Despite what a couple of people have said, time of year has absolutely no effect on aurora, since it's governed by solar activity. They are perhaps seen more often in the winter because the nights are longer, but are equally common at any time of year.

At night in winter is the best time to see them.

Answer 3

Pretty much forever. Meteor "showers" come from the remnants of old extinct comets, and some older comets that are not yet extinct. Dust and pebbles that boiled away from the comet during the last few thousand passes continue to follow, mostly, the orbit of the comet, and over the course of the centuries, the dust going a LITTLE faster and the dust going a LITTLE slower have spread out and pretty much filled up the orbital path.

Once a year, the Earth intersects that path, and the dust and gravel strike the Earth instead of going along their way in the comet's orbit. Depending on how old the comet was, or how long it has been extinct, the dust path may be wider or narrower, but at most the path is only wide enough for a few days travel as the Earth pokes through it. A couple of meteor showers last a week or more, but for most of them, the Earth has passed through in only one or two days.

Answer 4

There is not a set amount of times. They occur because of unusual activity on the sun. That can happen at absolutely any time. So you could have it lots of times in one year and very few times in another year. The activity on the Sun is unpredictable. When astronomers do see some unusual activity on the Sun, they can then predict that the Northern Lights will be seen in the coming days.

Answer 5

during winter, summer and it must be at night

About Three Hours

Answer 7

a meteor shower lasts around 15 minutes

Answer 8

in December
