A radio burst from the sun.

Recording of a radio burst received in the shortwave band from the sun. For detailed information on how this burst was detected visit the NASA Radio Jove project web site: http://jovearchive.gsfc.nasa.gov/

I thought that noise was cosmic radiation at the back of space from the Big Bang!?

This emission is in the shortwave decametric band. The cosmic background radiation is in the UHF bands if I'm not mistaken. Someone may have to correct me on that. Its def not associated with the shortwave bands.

Excelent video that shows actual "tangible" solar activity you can get by ordinary means (in this case, with a short wave receiver).

I was wondering what interfase did you use to send the noise to the computer?

And what software did you use to show the signal strenght. What meassure is that? mVolts?

I'm subscribing to your videos. They're really educational and in a plain language. They're really useful to show them to non expert people. Keep 'em comming!

The burst was detected using the NASA Radio Jove project setup. For detailed information on the equipment and setup visit the NASA Radio Jove project web site. I will place the link in the "about ths video" field.

whats this mean?

[truemartian]

Not sure yet but its really exciting to observe. Usually, but some say not always, these shorwave radio bursts are associated with sunspot activity. At times they can also indicate an x-ray burst.

my cb radio in my truck does this everynow and then. i keep the squelch off to get far away signals. the background noise is usually faint. but once in a while ill be sitting in the truck at home listening to the cb radio. the background noise is very faint but suddenly spikes up just like in this video. im using a 4foot fiberglass whip antenna. i may be getting this signal as well.

Well, you did. There are electromagnetic fields in the air that inputs into your speaker's circuit board, and transform them into audible waves. It's also called "Noise" (Obviously, it's a noise, lol).

I used to get noise like this coming from my 5.1 speakers which often picked up stuff on the airwaves. Who knows I might possibly have had my own radio telescope without even realising.

Very nice Jason! It's so unbelieveable, that often I got Jupiter bursts with my 4 element yagi as strong as this is from Sun, but NEVER tryed the Sun actually - daytime meant sleeping :) I still have the receiver complete with the band-pass filter and calibrator, just would need an antenna and a great SAFE field! What a shame that my nice "little" antenna is stolen :(
