The Simplest Solar Microbursts Flux and Circular Polarization at 22-GHZ
Abstract
The simplest solar microwave microbursts detected with high sensitivity may be the response to the simpler energetic burst injections. Seventeen events from this category were identified in a series of more than 150 bursts recorded in 21-26 November, 1982. This first systematic study suggest that microbursts e-folding rise times concentrate into two classes of time scales, 0.05 s < t ≪ 1 s and 0.5 s ≤ t ≤ 2 s. Microbursts' circular polarization present a dominant steady or slowly varying component that sets in before maximum emission. In some cases a faster component of polarization was found superimposed, which is not always well correlated in time with flux.
