Concerned about Light Pollution? - Join the Star-Hunting Party March 22 –29

You are invited to participate in a worldwide campaign to observe and record the magnitude of visible stars as a means of measuring light pollution in a given location. Although mainly aimed at students and families, anyone can join in. See the GLOBE at Night website for more information and post your results on their website.

If you also copy me with your results, including your location (You can find your lat long on the Multimap website, just centre your location on the map and read off your location on the map information) I will generate a local light pollution map for publication on the CAS website.

Note the dates include our dark site observing session on 24/25th March so why not come along and check how dark the site is.


  1. Hi all I have never posted before but would like to offer all you newbie’s and relative experts a new and alive forum through the BBC sky night.
    I have been a member for a short while and must say that everyone is really helpful and we have some excellent residents that will help you out with the most technical question and even the simple questions will be answered.
    I find with many forums they go dead or are all primarily American which can cause problems with time delays etc. but not here most are UK residents and their is over 650 members and at least 200+ post on a very regular basis . It is a very easy sight to navigate and use.

  2. Thanks for the tip John. I'm sure there will be some useful stuff there for many of us.
