Radar Meteor Reflections
Amateur astronomy doesn’t only involve optical observing. Data can come from monitoring radio waves, specifically 143.05MHz, which are being reflected back to Earth by the ionised trails of meteors. The radio waves originate from the GRAVES space surveillance radar in France pointing out over the Mediterranean. As meteors come in sporadically over the Med and Southern France, the leave ionised trails behind them that reflect the GRAVES radar back towards the UK. You can find out more about it at:
