While visiting the Grasmoor area of the Lake District in England on a foggy autumn day, we couldn't help but notice a ray of sunshine that suddenly appeared in the mist above. When we turned our back to the Sun, we could see a shadow (Brocken spectre) and colored rings (glory) cast onto the fog bank below. Moments later, we were again engulfed in fog. The glory and Brocken spectre are both diffraction phenomenon. They form at the antisolar point when the shadow of the observer is projected forward through the fog droplets. Note that the shadows converge at the antisolar point. Photo taken on October 9, 2010.
