[FireballNetwork (Phil)]

We’ve developed a smartphone app that allows anyone to report a fireball sighting anywhere in the world. Its designed so that we can potentially get data of sufficient quality to create a crowd source smartphone fireball network. Its free, (I hope!) fun to use, and it has a very easy interface - simply point at the sky where you think the fireball started and click on your phone, and do the same for where you think it ended. You can then input a variety of other data. If we get enough observations we can determine a trajectory and send that information back to you – for instance, you might get a message that the rock that made your fireball came from the outer asteroid belt, or that it was a chunk of a comet. The app also includes images and updates from our project. It is available for both iOS (https://itunes.apple.com/au/app/fire...709019924?mt=8) and Android (https://play.google.com/store/apps/details?id=com.tw.fireballs) (or just search for ‘fireballs in the sky’ on app stores). Let us know if you have any problems, or suggestions for improvements. Hope you have fun with it!
