Huddersfield Lights Out!

Castle Hill - Huddersfield
Castle Hill Side, Huddersfield, West Yorkshire, HD4 6TA
Huddersfield Lights Out is a campaign to address the ever-increasing problem of light pollution in and around Huddersfield.
The event aims to encourage as many people and businesses as possible to turn off lights on 25th September 2022 and is the brainchild of local astronomer and activist Mark Harrison.
A focal point of this event is Castle Hill, just south of Huddersfield, which offers an excellent vantage point over the town and, if it’s clear, the opportunity for a stargazing session, thus highlighting just how much of the night skies are drowned out by wasted light. (Note that the stargazing session at Castle Hill is to be confirmed).
If you would like to support this campaign, please contact Mark via his Facebook group page Huddersfield Lights Out.
Please note that this has already taken place on 25/09/2022
