It turns out that with simple equipment you can hear when meteors pass overhead even if you can't always see them. As a reminder: tonight the Perseid shower, a strong meteor shower
A meteor shower is a spectacular sight, but what to do if there are clouds in your area? Did you know that you can "hear" a meteor shower? If you operate amateur radio stations, is it possible to track the ion trails that the meteors leave in the atmosphere and enable the event to be broadcast to rockier radio receivers? You don't need sophisticated equipment to listen to a meteor shower, just an FM radio and an external antenna. Even the car radio can work well.
When a meteor passes over our heads, we hear for a short time transmissions from distant stations, explosions, buzzes, rings, shrieks, howls and simply changes in the white noise. Sometimes the phenomenon occurs in moderation and sometimes it hits all at once. One thing is for sure, the noises you hear are definitely coming from outside our world. The writer of the article in Universe Today, Tammy Plotner writes that she picked up the transmissions from the passing meteors with all kinds of radio receivers, including a simple transistor as well as using a television connected to an external antenna tuned to channel 3 (if I'm not mistaken it's VHF). All for fun and the results are amazing.
This Friday, at 19:00-20:00 UK time (22:00-23:00 Israel time), the BBC will broadcast live from Trafalgar Square in London, in which the editor of the astronomy program at the British Broadcasting Authority will demonstrate how radio signals are received during a meteor shower. . It will be as part of the Fourth Column performance where people change every hour on the Fourth Column in Trafalgar Square, the column on which there is no statue. The performance, in which ordinary citizens will take turns for 100 days, 24 hours a day, initiated by the sculptor Antony Gormley. – to the performance site
And for those who want to understand exactly what a meteor shower is and what the connection is between cars, flies and meteors, and why the closer you get to the morning the more meteors you see, please refer to our previous article on the subject: The Perseid shower: tonight and tomorrow the records - an opportunity to learn what a meteor shower is.
Also, the Israeli Astronomical Society will hold an observation on Friday of what remains of the Perseids (but they will be seen better in the absence of a moon). The observation in collaboration with Sde Har Hanegev School in Mitzpe Ramon Details on the association's website.

How will I know if I caught a meteor shower or if my device just went crazy?
How meteors affect radio reception. When a meteor falls it leaves behind a trail of pigeons. The radio waves are returned by the ionized region - similar to the return of short-wave radio transmissions from the ionosphere - which allows the reception of short-wave transmissions (3 to 30 MHz) almost all over the world. In the case of meteors, the ionization is in a smaller area and at a lower altitude, therefore it works more on the shorter waves - in the range of low radio frequency (30 to 150 MHz). By the way, this phenomenon is used in military communication systems and remote control systems that transmit data in short communication bursts - because at any given moment there is here and there some meteor suitable for this purpose (more than one per minute), even if it is not during a meteor shower that we usually observe. The system constantly transmits short bursts of communication, until it receives reception confirmation from the other station. This technique is called meteor burst communication.
Aiza, they were beautiful D:
Wai
I saw some 43
And they were consecutive
Um, do you know when it's supposed to be?
Because I heard it was supposed to be tonight like on the 12th of the month.
Cool
I think I picked up the changes in the white noise on the computer. Can be?
Or is it some new virus 🙂
"...we will briefly hear broadcasts from distant stations..."
I didn't understand how this was supposed to happen. explanation?
To which station should you tune the radio to try to hear?
Does anyone know of a good place in the Nethav area for a good observation of the meteors?
I am beautiful and you are beautiful
