Location of sources of solar noise storms relative to the structure of extrapolated coronal magnetic fields.
Abstract
A comparison is made of the positions of sources of solar radio noise storms, observed at 169 MHz, with the structure of the lines of force of the extrapolated coronal magnetic field in a current-free approximation. The typical position of the permanent radio source was found at the top of the coronal arch connecting the active region with the opposite polarity of the background magnetic field in its immediate vicinity. No direct relation was found between the flare activity in the active region and the presence of the radio source.
