Figure 2From: Coronal magnetic field and the plasma beta determined from radio and multiple satellite observationsTime variation of the total soft X-ray and EUV flux of the active region. (Top) Time variation of the total soft X-ray flux of the Sun observed with GOES 15. (Bottom) Time variation of the EUV flux at 195 Å observed with STEREO_A. The flux plotted is the average flux over the active region marked by the white rectangle in Figure 3c.Back to article page
