The polarization of U-shaped solar radio bursts.
Abstract
Circular-polarization measurements of 11 U-shaped solar radio bursts observed at 237 MHz are reported which contradict the expectation that the received polarization should have different signs in the two branches. The mean polarization of these bursts is found to be about 7% righthanded for the ascending branch and about 6% in the same sense for the descending branch. An attempt is made to discuss the observed constancy of the sign of polarization in terms of coronal propagation properties above the source region.
