From space; a colored halo or some ''glowing veigns''
On Earth they often look like green clouds. On RARE occaisions you get the stereo-typical ''curtain'' like aurora. Sometimes they are just thin glowing strips of light in the sky, and sometimes you can't really see them, because they flash really quickly for several flashes before stopping.
shimmering curtains of light
''Aurora'' means Dawn and ''Borealis'' means North. So basically Aurora borealis means ''Dawn of north''.
The astronomical phenomenon, aurora borealis as they appear in motion, move very slowly, like watching a gentle breeze blow on a curtain.
"The Northern Lights" is Aurora Borealis's commonly used name.
When the Aurora Borealis happen, they can be seen from the Aleutian Islands.

Aurora Borealis occurs in northern parts of the world. Aurora Australis in southern parts of the world. Borealis is more known because there are more places and people to see them.
Aurora boreal, or even more technical, you can also say it as in Latin "Aurora borealis"[au̯.ˈɾo.ɾa.βo.ɾeˈa.lis]
The aurora borealis occur at times of heightened states of solar activity, this also applies to the aurora australius.
Aurora Borealis is caused by particles hitting earth's atmosphere thermosphere and they are stopped, so they give of their energy in the "Northern Lights" or Aurora Borealis.
