A triple sun shined above the sky in Hailun City of northeast China’s Heilongjiang Province on Monday morning, mesmerizing residents in the area. The celestial illusion appeared at around 08:30, with two smaller suns on each side of a bigger one.
Maria Borukha, head of popular science at the St. Petersburg Planetarium and a current PhD student in celestial mechanics at St. Petersburg State University, said the false suns were known as ‘sun dogs’. She explained that they were an atmospheric phenomenon consisting of a pair of bright spots appearing on either side of the Sun.
They can be seen anywhere in the world during any season but are rarely seen as brightly as they were in the St Petersburg area. But Nikolay Zheleznov, senior researcher of the Institute of Applied Astronomy of the Russian Academy of Sciences, said some halos were even more eye-catching.
