Light pollution maps are a useful tool for astronomers, photographers, and anyone who wants to observe the night sky. These maps allow users to locate dark sites where the sky is unaffected by light pollution, providing the best conditions for stargazing and astrophotography. Light pollution limits the visibility of the Milky Way, nebulae, and galaxies to the naked eye or through telescopes, and affects the quality of astrophotographs. Light pollution maps often come with additional features such as cloud cover overlays, alerts for astronomical events, and information on moon phases and times.

Astronomy tools
Light pollution maps are an essential tool for astronomers, both amateur and professional, as light pollution can limit the visibility of the Milky Way to the naked eye and affect the observation of nebulae and galaxies through telescopes. Light pollution maps help users find dark sky locations and optimal stargazing spots.
One such map is available at lightpollutionmap.app, which covers most countries and regions worldwide. The map combines light pollution levels with geographical data to help users locate ideal spots for Milky Way observation and photography. It also provides Bortle class information, which is a standard way to measure how dark the night sky is at a particular location. The Bortle Scale ranges from Class 1 (pitch black) to Class 9 (heavily light-polluted), with lower numbers meaning more stars are visible. The website also plans to add features like Milky Way rise times and direction to support astrophotographers in planning their shoots.
Another light pollution map is available at lightpollutionmap.info, which displays light pollution-related content such as SQM/SQC measurements, World Atlas 2015 zenith brightness, and aurora prediction. The website also provides a list of options and features to help users analyse the data, such as the ability to filter SQM points by name or date and observatories options to assess light pollution levels.
In addition to these online maps, there are other tools available to measure sky brightness, such as the Sky Quality Meter (SQM), a small device that measures sky quality (i.e., darkness) and is widely used by amateur astronomers due to its low cost and fast results. There is also a smartphone app called Clear Outside by FLO, which uses your current GPS location to present an accurate reading of where your night sky falls on the Bortle Scale.

Aurora Borealis viewing
Light pollution maps are tools that help users identify local light pollution levels and locate dark sky sites, which are ideal for astronomical observations and viewing the night sky. These maps can be used to plan trips to dark sky sites and view celestial events such as the Aurora Borealis.
The Aurora Borealis, also known as the Northern Lights, is a mesmerizing natural light display visible in the night sky. It occurs when charged particles from the sun collide with gases in the Earth's upper atmosphere, creating colourful curtains of light. The best places to view the Aurora Borealis are within the "auroral zone", an area within approximately 1,550 miles (2,500 kilometres) of the North Pole. This zone includes locations such as Norway, where the Aurora can be viewed along with the beautiful Norwegian coastline.
While the Aurora is most frequently visible within the auroral zone, it can occasionally be seen in other parts of the world due to heightened solar activity. For example, the Northern Lights have been witnessed as far south as Cornwall and Brighton in the UK. However, even in these locations, certain conditions are required for a clear viewing experience. Dark and clear nights with minimal light pollution are ideal for observing the Aurora. Light pollution refers to man-made lights that can obscure the night sky and alter the appearance of the Aurora.
To improve your chances of successfully viewing the Aurora Borealis, consider the following tips:
- Utilize light pollution maps to find areas with low light pollution, away from bright city lights and billboards.
- Dim or turn off unnecessary lights at home or in your business premises to reduce light pollution and improve visibility of the night sky.
- Pay attention to streetlights and exterior lighting in your surroundings. The style of bulb and direction of the light can make a difference—advocate for lighting that points downwards and minimizes light pollution.
- Check websites like AuroraWatch UK, which provides estimates of the likelihood of Aurora visibility based on geomagnetic activity.
- Consider joining astronomy-focused trips or voyages that combine Aurora viewing with educational lectures and scenic experiences.

ISS tracking
Light pollution refers to the brightness of a given area as observed from space, based on the light emitted and reflected from the Earth's surface. Light pollution maps are useful for stargazers and astronomers, helping them find suitable observation locations and providing basic astronomical guidance.
The Light Pollution Map app is one such application that displays light pollution-related content. The app combines light pollution levels with geographical data to help users locate ideal spots for Milky Way observation and photography. It also includes a cloud cover map and temperature indicator, so users can determine whether it is worth going outside to view the night sky.
The app also features an ISS Tracker, which allows users to follow the International Space Station on a live map, see when it is flying above their location, view a live ISS webcam, and find out who is currently on the ISS. The ISS Tracker also fixes issues with the cloud layer, people in space, the ISS live stream, and aurora webcams.
The Light Pollution Map app sources data from NASA's VIIRS SNPP/NOAA-20 Lunar BRDF-Adjusted Nighttime Lights Yearly composites, which are typically updated annually. The app also uses SQM (Sky Quality Meter) data, which shows night sky brightness in precise numbers, measured in magnitudes per arcsecond squared (mag/arcsec²).
In addition to the Light Pollution Map app, there are other tools available for ISS tracking and light pollution mapping, such as the ISS Tracker on isstracker.pl, which provides maps of light pollution for various towns and cities.

Meteor shower alerts
Light pollution maps are a useful tool for stargazers and astronomers, helping them to find dark sky sites with minimal light pollution. Light pollution reduces visibility, making it harder to observe celestial bodies such as nebulae and galaxies, and can also affect astrophotography.
Now, if you're specifically interested in meteor showers, there are a few things you should know. Firstly, meteor showers are typically easy to observe, as long as you find a location with a clear, dark sky and look up! However, visibility can be affected by various factors, including weather conditions, the moon phase, and the amount of light pollution in your area.
To maximise your chances of catching a meteor shower, there are interactive meteor shower sky maps and guides available online. These tools can help you find the best times and locations to view upcoming meteor showers, such as the Perseids in August, the Draconids in October, and the Geminids, which typically peak in December.
For example, the Perseid meteor shower in 2025 was expected to be visible from mid-July to early September, with a peak in activity around the solstice. The Draconids, also in 2025, were predicted to peak on October 8, with the best viewing conditions after dark on that evening and into the early morning hours of October 9.
By utilising light pollution maps and meteor shower alerts, you can plan your stargazing sessions effectively and increase your chances of witnessing these celestial events. So, whether you're chasing the Perseids, Draconids, or any other meteor shower, stay informed, find a dark sky site, and enjoy the show!
