Description: A 10cm radio burst indicates 

that the electromagnetic burst associated with a 

solar flare at the 10cm wavelength was double 

or greater than the initial 10cm radio background. 

This can be indicative of significant radio noise

in association with a solar flare. This noise 

is generally short-lived but can cause interference 

for sensitive receivers including radar, GPS, and 

satellite communications.
