The 10 July 2012 Event: An Example of Narrowband Gyrosynchrotron Burst?
Abstract
We have identified events with steep (narrowband) microwave spectra that do not show a prolonged trapping and imply some degree of source uniformity. We revealed event of 10 July 2012 with such narrow spectra, having low- and high-frequency spectral indices larger than 3 in absolute value during the flare. Based on an analysis of radio images dynamics we concluded that even narrowband burst had the complex structure, consisting of two sources - low and high frequency ones. The behavior of each was very differ that appeared in spectrum shape and spatial structure dynamics.
