Current Meteor Activity

Amateur astronomy doesn’t only involve optical observing. The data below comes 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:

The two images below show the latest frequency profile on an incoming meteor signal and show the hourly counts over recent 24 hour periods. The latter clearly demonstrates that 3am to 5am is a great time for observing meteors.
