The International Dark Sky Association works hard to publicize the growing problem of light pollution. For astronomers and astronomer wannabes like you and I, their work is really helpful.
On March 16-28, the Association is asking folks to submit reports about sky darkness to their website for a worldwide survey. Taking part is a really great way to help out the wider astronomical community.
All you need to do is go out between these two dates, take a look at the constellation Orion and then compare it to one of their online photos. That's all. Easy stuff!
