Is there a light pollution app?
A new app just released for the Android OS, called “The Loss of the Night” is designed to find out exactly how bad the light pollution is. The app helps measure skyglow by learning which stars are visible or invisible to the naked eye at the user’s location.
What is Bortle class scale?
The Bortle scale is a nine-level numeric scale that measures the night sky’s brightness of a particular location. The scale ranges from Class 1, the darkest skies available on Earth, through Class 9, inner-city skies. It gives several criteria for each level beyond naked-eye limiting magnitude (NELM).

Where can I find Bortle 1?
In New Mexico between the western New Mexico border and Pie Town (hwy 60), I have seen strange looking gray skies that are in areas designated as being Bortle 1 skies. At dark sky sites in Arizona the skies are gray, but the ones in NM are a different kind of gray.
What is sqm light pollution?
A sky quality meter (SQM) is an instrument used to measure the luminance of the night sky. It is used, typically by amateur astronomers, to quantify the skyglow aspect of light pollution and uses units of “magnitudes per square arcsecond” favored by astronomers.
How do you measure light pollution?
Light pollution measurement
- Handheld devices. Sky Quality Meter (SQM)
- Photometry. star-free regions on the CCD images is extracted to estimate the NSB.
- Star-counting. Match nighttime sky to one of the magnitude chats Picture source: Globe at Night.
- Satellite imagery.
- Spectroscopy.
How does Bortle scale work?
The Bortle scale uses astronomical observations to measure the amount of light pollution for a given location. For example, a Class 1 Bortle sky means that one can observe M33 (Triangulum Galaxy) as a direct-vision naked eye object.
What is bortle sky?
The Bortle Scale is a useful way of estimating your sky brightness, i.e. to what extent light pollution affects your view of the night sky. By going outside on a clear moonless night and recording what astronomical objects you can see you can assign a Bortle Class rating to your observing site.
What app do astronomers use?
Skyview. The Skyview app is $2 on iOS and Android, but both platforms have a free lite version. To use Skyview, just point your device at the sky and you can get started identifying galaxies, stars, constellations, planets — even the International Space Station.
