Unusual halo around sun
An unusual halo. A halo is formed when light from the Sun is refracted by tiny hexagonal ice crystals high in the atmosphere. The most common halo is 22 arc-degrees in diameter. Here, several halos coincide, with diameters of approximately 18, 38 and 47 arc-degrees. The exact cause of this unusual halo formation is unknown, but similar observations were made in the USA in 1987. This halo was photographed in Finland on 14 May 1988

EDITORS COMMENTS
This print captures an extraordinary sight in the sky - an unusual halo around the sun. Halos are optical phenomena that occur when sunlight is refracted by minuscule hexagonal ice crystals high up in the atmosphere. While a typical halo measures 22 arc-degrees in diameter, this particular image showcases several halos coinciding with diameters of approximately 18,38, and 47 arc-degrees. The exact cause behind this peculiar formation remains unknown, adding to its mystique and allure. Interestingly, similar observations were documented in the United States back in 1987, suggesting that these rare occurrences may have some connection across different regions. Taken on May 14th, 1988, in Finland by Science Photo Library (not affiliated with any commercial use), this photograph serves as a reminder of nature's ability to surprise and astonish us. It highlights how atmospheric conditions can create breathtaking visual effects like this mesmerizing halo around our celestial star. As we gaze upon this remarkable image, it prompts us to marvel at the intricate interplay between sunlight and ice crystals within our atmosphere. Such wonders remind us of the beauty and complexity inherent in our world's climate system while also inspiring further exploration into meteorology and atmospheric science.
