What is Shadow Flicker?
Before the threat of the windfarm at Ingram Grange you may never have heard of shadow flicker.
Shadow flicker occurs in the shadow of a turbine when the sun is behind the blades It happens when the sun is low in the sky in the early
mornings and late evenings
Shadow Flicker can also occur at night when the moon is bright around the full moon Shadow Flicker can make concentration and tasks such as reading impossible
There are no photographs of shadow flicker because it is created by moving turbine blades    
Shadow flicker is best demonstrated by watching a video
Shadow Flicker creates a strobing or
pulsing affect
It combines with the rythm of the noise
It can cause problems with concentration,
anxiety and stress
It can keep you awake at night when
the moon is full around the full moon
Here is one person's description.
What I suffered was what I'd describe as motion sickness. The turbines at Boulfuich are 3 miles (4.8km) from my office window and when the sun is shining on them they are very bright. When they turn, the movement is particularly mesemerising and, as the centres of some of the turbines are just below the horizon, the movement creates a circular movemenet of my head as well as my eyes. This obviously is what makes me dizzy and sick - like being sea-sick. The blades are fully visible on some turbines but others "cut" the horizon - these are the worst for causing visual disturbance in my experience. Because the view is framed, I have no escape from the motion, all the turbines are visible right across the window-view, 15 turbines at 67m to tip so they are not huge.
