If you can bear the cold.. The Ursids are coming

SPACE WEATHER ALERT:

RADIO METEORS: The Ursid meteor shower caused by Comet 8P/Tuttle peaks this year on Dec. 22nd. About a dozen meteors per hour will fly out of the Little Dipper (Ursa Minor) as Earth passes through the comet’s debris stream.

Watching these northern meteors can be a chilling experience, so why not stay inside and listen to them instead?

Spaceweather.com is broadcasting live audio from the Air Force Space Surveillance Radar in Texas. When a meteor passes over the radar–"ping"–there is an echo. Give it a try; feedback is welcomed.
