April 29, 2006   More Solar Radio Bursts (stronger today)

Click just below for an audio specimen recorded in stereo at 22.2 MHz and 18.7 MHz.
Headphones will let you hear this burst event as it drifts down in frequency, hitting first at 22.2 MHz in one earphone,
then a moment later it will pass down through 18.7 MHz in the other earphone.

Also, the above particular emission specimen may have emanated from an active region that is just now coming around the northeast limb of the Sun.
Analysis is not yet complete but you can see a movie of this time period at:

And another burst:



Click just below for a strong Type III solar burst, also called a "fast drift burst".  This particular burst shoots fast
 through the earphones as it passes down from 22.2 MHz through 18.7 MHz.

And another "fast drift burst"  later in the day:



The following audio specimen is 22.2 MHz monophonic only due to some interference that penetrated
my 18.7 MHz channel at the moment of the emission. Yet, it is still a good example of a Type III radio burst.
