Have you ever heard the Sun?
the Sun in New Mexico with a multi-frequency
radiotelescope that has been modified
and customized for binaural audio recording. Here is
a collection of specimen sound files of the
major types of solar radio emissions from some significant
events in recent years.
Headphones or speakers with good stereo
separation encouraged for strongest and
most intricate pulsation experience.
Moderate to loud volume encouraged but please don't hurt your
Observer's Comment: February
The Sun is currently emerging out of a very long period of "sunspot
minimum" and a new solar cycle has now begun.
Fresh activity is now happening and I will be manifesting a new website
to accommodate it all. - Thomas Ashcraft
November 6, 2006 A Very
Fast Solar Shock Front Today and Coronal Mass Ejection
There was a C9.7 solar X-ray flare today that caused moderate
to strong Type II bursting from 1740 to 1749 UT. This flare
event is still
being analyzed as I write. Below is an audio file recorded
in stereo of the strongest part of this solar shockwave event that
1744 UT and 1748 UT. Recorded at 18.7 MHz one one
channel and 22.2 MHz on the other channel. This was
fast Type II radio burst event recorded traveling from
the Sun at 2230 kilometres per second! It sounds like a freight train
peak.mp3 3 minutes 59 seconds
December 6, 2006 An
X6.5 X-Ray Solar Flare and a rare Moreton Wave
is supposed to be the time of solar sunspot minimum but a new spot
group has emerged - region 10930 - and it just blasted out its second
We captured the shockfront of this X6.5 flare at 1843 UT
and you can hear it below recorded at 22 MHz.
The shockfront and super-complex solar plasma oscillations
kick in at about 19 seconds into the sound file.

There is a dynamic sunspot group on the Sun
today and it has been producing many moderate to strong radio bursts
the past three days. This Type V emission was
one of the strongest so far. Recorded in stereo at 18.7 MHz
and 22.2 MHz.
If you listen closely you will hear the burst hit one
one stereo channel then a split second later hit the other as
the burst drifts down in frequency.

2200 UT And yet another X Flare from Region 10930!
We were lucky to catch a slice of these powerful
solar radio sweeps at 22 MHz while the Sun was still in our antenna
beams. The full radio
event was a complex mix of Type II, Type IV and Type V radio
emissions and we caught the hottest part of the complex at 2220 UT.
Here is an excerpt and
the sound takes off at about 15 seconds into the sound file.
