Goat Willow Seed Corona

Around noon on April 22, 2011 (Good Friday), I went to a hedge near Limburg (Hesse, Germany). As the weather was sunny and dry, some goat willows (Salix caprea) sent a large amount of seeds into the spring air. Together with the bright mid day sunshine, these caused some surprising effects. Often there was just one bright area around the sun (1–2–3), but from time to time a colourful corona appeared in the seeds.
