But not always.
 
Lightning is one phenomenon best observed at night.
 
Astronauts aboard the space station have a unique view of lightning strikes.

(DESCRIPTION)
Astronauts of captured images of the rarely witnessed lightning phenomena called "red sprites."
 
On the Earth's horizon, a red shape over a purplish-white shape on the ground.
 
The jellyfish-like red sprites are cold electric discharges, similar to the emissions of a fluorescent light tube, that seem to occur during large thunderstorms.
 
The sprites tendrils reach as far as 60 miles (100 kilometers) above Earth's surface.
 
Earth from a space station. Text, Red sprites are difficult to observe, because they last just milliseconds and appear above thunderstorm clouds, which usually block our view from the ground.
 
Earth orbit provides a good perch from which to study these elusive phenomena.
