VLA Observations of Narrowband Decimetric Burst Emissions
Abstract
The Very Large Array was used to observe a multiply-impulsive solar radio burst at several wavelengths near 20 cm. The observations indicate that the impulsive emission was nearly 100% circularly polarized and originated in small regions of ∼ 10″-20″ in size. For one of the impulsive spikes, we find evidence of narrow-band emission that could be attributed to an electron-cyclotron maser. The radio data are also compared with soft X-ray data and interpreted in light of a model in which the coronal plasma is heated by maser burst emission.
