Tumbling and Flashing Satellite Introduction


Provides a great intro to the fascinating art of timing tumbling satellites. Follow the links within for the how and why and how to report the periods and optical characteristics.

I find this part of the work the most fun - seeing a flasher unexpectedly and figuring out which one it is and its status is very satisfying. In several cases, reporting this data has helped determine if a new satellite is in trouble, or if a rocket body is out of control or has fragmented.
