- SATFLARE - In this page you can track in real time all the satellites orbiting the Earth, with both 2D and 3D interactive representations, predict their passes, view their trajectory among stars on an interactive sky chart, predict satellite flares and transits (across the Sun and the Moon), find out the best location to see these events on a detailed Google map. You can also follow satellite re-entries and other special events, join the observer community, post messages and share your comments and observations. Currently in our database we have more than 9000 observation reports!
