 Solar Halo Above Eastern Slovakia

   Summary Authors:  Róbert Hlava;  Jim Foster

   Shown above is an eye-catching  22-degree solar halo and  glitter
   path that I observed over eastern Slovakia on the morning of January
   18, 2020. Halos such as this one may result when  hexagonal ice
   crystals, either in  cirrus clouds or freely falling through the
   lower atmosphere ( diamond dust), act like miniature prisms,
   refracting and dispersing sunlight. If the axis of a pencil-shaped
   crystal is approximately perpendicular to the direction of sunlight, a
   ray of sunlight will pass through two of the  crystal’s side faces
   and be refracted roughly 22 degrees. Millions of these more-or-less
   randomly oriented crystals form circular halos.

   I was ecstatic to be able to witness both the atmospheric halo and the
   glitter path on the ice-covered lake. Nature always seems to offer new
   surprises for us.  Make sure to protect your eyes when looking
   toward the Sun.
