Heiligenschein, or hotspot, around the shadow of a hot-air balloon cast on a field of standing crops (Oxfordshire, England)

Heiligenschein (German for "halo" or "aureola", pronounced ['ha?lna?n]) is an optical phenomenon in which a bright spot appears around the shadow of the viewer's head in the presence of dew. In photogrammetry and remote sensing, it is more commonly known as the hotspot. It is also occasionally known as Cellini's halo after the Italian artist and writer Benvenuto Cellini (1500-1571), who described the phenomenon in his memoirs in 1562.[1]

Nearly spherical dew droplets act as lenses to focus the light onto the surface behind them. When this light scatters or reflects off that surface, the same lens re-focuses that light into the direction from which it came. This configuration is sometimes called a cat's eye retroreflector. Any retroreflective surface is brightest around the antisolar point.

Opposition surge and glory are similar effects caused by different mechanisms.
