Outer corona image. Hungary. Total solar eclipse of 1999 August 11 was near the maximum of 23rd eleven-year solar cycle. The coronal structure is changing during the eleven-year solar cycle significantly. It is spread approximately evenly to all spatial directions near solar cycle maximum (for example eclipses 1990, 2001, 2002). The structure is completely different near solar cycle minimum when the coronal intensity is much greater in equatorial plane than in polar regions (for example 1994-1995). Composite of 27 images.
