Wow. that was interesting. Did anyone realised that some of the backgrd stars didn't even moved. And i'm kind of interested in the random thing that looks like lightning. Can anyone tell me what that is?

Yah, really nice video..

The 'stars' that didn't move are probably hot pixels on the camera, while I think that those random arcs are caused by insects flying in front of the camera. As you see from the trees in the foreground, there seems to be a light that will illuminate insects as they fly nearby.

Rgds,
Chris

Those lightning thingies look like poor video quality to me.. Digital noise? :?
I love the stars too much to be afraid of the dark.

I think they are insects flying in front of the camera.

Cheers.

From Wikipedia: Auroras are now known to be caused by the collision of charged particles (e.g. electrons), found in the magnetosphere, with atoms in the Earth's upper atmosphere (at altitudes above 80 km).
http://en.wikipedia.org/wiki/Aurora_(astronomy)

Reis: Bcos they occur on earth's surface, u'll see stars (insects, digital noise...etc) :wink: in the background. Visibility of the stars in the background depends on the intensity of the Aurora (and likewise the magnitude of the stars). Try this link and you will see the same "insects": http://www.youtube.com/watch?=D9XP5akG9 ... ed&search=

The variety in colour comes from the particle collision with different atom of gas like oxygen...hydrogen... and so on... :idea:

Aurora & (particularly) Cassiopeia admirers :wink: would love this clip! Magnificent! Very intense display of lights... directed by Nature.
