Rare sun halo spotted in Singapore skies March 15
A rare sun halo appeared in Singapore on March 15, 2025, creating a bright ring around the sun. The phenomenon was visible from various locations, including Bukit Panjang and Bedok, and photos circulated widely on social media. Senior Minister Lee Hsien Loong shared a photo of the halo, describing it as a "22-degree halo." This optical effect occurs when sunlight interacts with ice crystals in high-altitude clouds, bending light to form the ring. The National Environment Agency noted that sun halos are uncommon in Singapore due to typical cloud cover. The last recorded sighting was on September 22, 2020.
