Shortly before Christmas, Kurier reader Georg Lettner photographed an extraordinary light reflection in Bad Heilbrunn, which he observed during snowmaking on Blomberg.

Bad Heilbrunn - "This is a very nice picture of a double ice halo," comments meteorologist Hartmut Mühlbauer from the online portal www.wetter.com on the reader's photo.

"Halos are caused by ice crystals in very high and fine clouds, so-called cirrus clouds, at a height of eight to twelve kilometers," explains Mühlbauer.

Ice crystals break down and bundle the sunlight

"In the case of the picture, you can hardly see the clouds, but the ice crystals are there." The ice crystals in these clouds break down and focus the sunlight.

"When the sun is low, a ring forms around the sun, and more rarely two rings," explains the meteorologist.

"The phenomenon occurs more frequently in winter, since the height of the sun and the mirror effect are optimal here."
