The inner image was taken with the SOHO EUV Imaging Telescope (EIT) and shows the solar disk in green as seen in the EUV waveband. The southerly white region shows the regions that flared, releasing energy. The outer image in blue taken with the SOHO LASCO telescope shows white areas which are regions of high-density gas and magnetic field leaving the Sun at a speed of over 900 km per second.
