The Star Count is running from 2-23 February 2019, but the darkest skies are expected 2-9 February, when the moon will be smallest.
Here’s how to take part in @CPRE's #StarCount2019 - a cosmic census to map light pollution.
1. Find the constellation of Orion in the night sky
2. Count the stars you see within the rectangle formed by the 4 corner stars
3. Submit your results: http://www.cpre.org.uk/starcount
You can do this from anywhere in England. We’ll use the information to create a new map of the nation’s view of the night sky. Star Count 2019 is being run in partnership wth the British Astronomical Association.
