Fig. A.2.


Superposition of the magnetic field lines from the PFSS model on an MDI magnetogram (a) and an EIT 19.5 nm image (b–c) on October 9, 2001. Radio sources of the stationary type IV continuum seen in Stokes parameter I at different frequencies are plotted in (b), and a noise storm in (c). Contours of equal brightness temperature at 50% of the maximum are plotted in colours to represent different frequencies.
