Putting citizen science data back in the hands of citizens!

I'm very pleased to announce that our new web application for viewing skyglow data taken by citizen scientists is now online, at!

It allows you to view where data has been taken:

Skyglow observations in Europe and northern Africa

It lets you view individual Loss of the Night app observations:

A single Loss of the Night app observing session by a citizen scientist

It allows you to do trend analyses to see how skyglow is changing:

 And it also allows you to access all of your own data, using the "My Measurements" tab.

It will take a few years of observations before the trend analyses start to be really useful, so go out and observe your night sky often! Bur right now, head over to, and have some fun exploring the data collected by tens of thousands of citizen scientists from around the world!
