A breathtaking iridescent cloud over Bogor, Indonesia, went viral, showcasing a rare atmospheric phenomenon that captivates viewers. Residents of Jonggol spotted these rainbow clouds last week.

Ida Pramuwardani from Indonesia’s Meteorology, Climatology, and Geophysics Agency (BMKG) confirmed the sighting. She stated, “The phenomenon seen in the video is a common occurrence in the atmosphere and is related to atmospheric optics.” This type of cloud occurs when sunlight diffracts off ice crystals.

The colors of iridescent clouds can change rapidly and often disappear quickly. They can appear in hues of pink, green, and blue. The pileus cap—a lenticular cloud—provided the consistent droplets required for this particular iridescence.

Such weather phenomena have been documented since at least 1911, when Edward Wilson painted iridescent clouds in Antarctica. Iridescent clouds have also been seen in Malaysia, Vietnam, and Singapore in recent years.

However, these clouds can be confused with nacreous clouds and coronae. Observers should exercise caution when viewing them directly, as they typically occur near where the sun appears.

The phenomenon sparked curiosity among locals and quickly gained traction on social media platforms.
