Sun Halo Rainbow at My Workplace

I'm so excited to see this rare sun rainbow halo today at my workplace at 11.38 am! It's the very first time I see a sun rainbow halo in 41 years! I hope to see more rainbow and may there be peace soon on this planet earth, the only home we have for now.

Later in the afternoon, it rained heavily. Based on Singapore weather forecast, we have rainy days for the next two weeks.

Those thin cirrus clouds are around 20,000 feet or higher above us. They are made of tiny, ice crystals. Sunlight through the ice crystals causes the light to split, or be refracted. When at just the right angle, it causes us to see the halo.

The same thin clouds can cause a ring, or halo, around the moon at night.

Weather folklore says a ring around the sun or moon means it will rain soon. While that is not always the case, it often is actually true.  Cirrus clouds typically move into an area well ahead of a storm system that may cause rain in the next day or so.
