According to foreign media reports and weather experts, the phenomenon was not the appearance of two suns but a natural atmospheric event.
Specialists explained that tiny ice crystals formed in the air due to extreme cold reflected sunlight, creating the illusion of the sun appearing in two positions in the sky.
This optical phenomenon is scientifically known as a “sun dog” (parhelion).
Reports said the temperature on Sakhalin Island was recorded at minus 14 degrees Celsius, with forecasts indicating it could fall to as low as minus 23 degrees Celsius.
Experts said such rare visual phenomena are more likely to occur in extremely cold weather conditions.
