On August 1st, Kevin Palivec of Hawley, Texas recorded radio bursts from the M2-class solar explosion.
The mysterious shortwave bursts detected in Texas had been created by a M2-class solar explosion. They were heard at 20.1 MHz. This chart recording displays 10 minutes of activity on August 1st:
According to Space Weather, ‘[…] the bursts were triggered by an M2-class explosion in the magnetic canopy of sunspot AR2127. The explosion sent shock waves rippling through the sun’s atmosphere. Those shock waves, in turn, excited plasma instabilities that emit static-y radio waves. Becase there are a whole variety of plasma instabilites, there is a corresponding variety of radio burst types. Palivec recorded a mix of two: Type II and Type IV […]’
