This
web site strikes new ground in further refining the definition of Light
Pollution. Based on the premise promoted by Catherin Rich
we try to show the fine points of light pollution. Light
pollution has always had a number of components; Urban Sky Glow, Glare,
Light Trespass, Over Lighting, and now Ecological and Medical aspects
are included.
Astronomical
Light
Pollution
- Urban Sky Glow, the classic
brightening of the sky over our cities and the brightening of the sky
over far away observing sites such as our National Parks and
Observatories.
- Glare, a common problem for Amateur
Astronomers in the form of "local" light pollution and often a
component of Light Trespass.
- Light Trespass, a common problem for Amateur Astronomers and average citizens alike.
- Indirect Light Trespass, a term used here to indicate Sky Glow, often caused by local sources which is so severe that it is as if a flood light was directly illuminating the property from off site.

It is easy to see that
Energy Waste is an important component, as it takes energy to destroy
the night sky.
