Ever seen a bolide or a fireball - a really big, bright shooting star? If so, you'll probably never forget it. You might have even tweeted, blogged or facebooked about it. Now, you can also report it via an easy to use report form to the International Meteor Organization (IMO) and make a contribution to science.
