A breathtaking iridescent cloud over Bogor, Indonesia, recently went viral as residents captured its beauty on video. This atmospheric phenomenon showcases the captivating effects of sunlight refracting through ice crystals found within clouds.
Ida Pramuwardani from Indonesia’s Meteorology, Climatology, and Geophysics Agency (BMKG) stated, “The phenomenon seen in the video is a common occurrence in the atmosphere and is related to atmospheric optics.” This comment highlights that such occurrences are not entirely rare but rather dependent on specific conditions.
The sighting took place last week in Jonggol, a region in Bogor, where residents were treated to a display of colors that can shift rapidly. These iridescent clouds typically exhibit hues of pink, green, and blue, captivating many who witnessed them.
The phenomenon has historical roots; iridescent clouds have been documented since at least 1911 when they were painted by Edward Wilson in Antarctica. However, the recent visibility of these clouds has sparked renewed interest across social media platforms.
Key facts about iridescent clouds:
- Iridescent clouds occur when sunlight diffracts off ice crystals.
- The colors can change and quickly disappear.
- The pileus cap—a type of lenticular cloud—provided the necessary droplets for this specific instance of cloud iridescence.
While the BMKG confirmed the authenticity and natural occurrence of this event, it is important to note that similar phenomena have also been reported in neighboring countries such as Malaysia, Vietnam, and Singapore in recent years. Such weather phenomena can be confused with nacreous clouds and coronae due to their similar visual characteristics.
Officials advise caution when observing these clouds directly because they typically appear near the sun. As this captivating display continues to draw attention from both locals and meteorological experts alike, further sightings may occur as weather patterns evolve.
