ARLA/CLUSTER: Escute as "estrelas cadentes" Perseidas a "cair", pela Internet

[João Costa > CT1FBF]

Listen to Perseid radio pings on the Internet

JoAnne K9JKM reminds us that radio pings from meteors can be heard via
the internet

The Perseid meteor shower peak is predicted to occur between August 11
to 13, 2014. There are a few pre-peak pings already audible. The
activity should increase over the next several days.

Quoting from their web page here is how they do it:

The US Air Force Space Surveillance Radar has been shut down, but
we're still recording meteor echoes. How do we do it? Radio engineer
Stan Nelson uses a Yagi antenna in New Mexico to detect 54 MHz TV
signals reflected from meteor trails. When a meteor passes over his
observatory--ping!--there is an echo.
