How many stars can you see in Orion?

We often say that light pollution is a growing problem around the world and is stopping us from seeing the night sky. Late last year Dave Pearson mentioned a UK project to quantify the problem. This was partially thwarted by the fog that beset the country over Christmas. The other problem, from a web point of view, was that it was too UK-centric. Now (spotted via Dave again) there is a similar project which aims to quantify the amount of light pollution on a global scale.

The project is called Globe At Night and solves the issues of time zones and latitude by using the constellation of Orion which can be seen by most people around the world. Great! Once you've found your latitude and Orion (the hardest part of the whole thing) all you need to do is compare what you can see in the evening sky with the images available on the Globe At Night website. Then submit your results. If you want to take part in this huge global observation, you will need to observe Orion on one night between March 8th - 21st 2007. The more observations made, the better the results will be.
