“The phenomenon seen in the video is a common occurrence in the atmosphere and is related to atmospheric optics,” said Ida Pramuwardani from Indonesia’s Meteorology, Climatology, and Geophysics Agency (BMKG). Last week, residents of Jonggol in Bogor were treated to a breathtaking display of iridescent clouds, showcasing hues of pink, green, and blue that quickly captured attention on social media.
This rare weather phenomenon occurs when sunlight diffracts off ice crystals within clouds. The conditions must be just right for iridescence to appear; typically, it manifests in the presence of a pileus cap—a type of lenticular cloud that provides consistent droplets necessary for the effect. The vibrant colors can change rapidly and often vanish as quickly as they appear.
As locals gazed up in wonder at the sky, the BMKG confirmed that what they saw was indeed a natural occurrence. Iridescent clouds have been documented since at least 1911 and have also been sighted in neighboring countries like Malaysia and Vietnam. The viral images sparked curiosity among viewers who were eager to learn more about this stunning display.
Ida Pramuwardani emphasized that while these clouds can be mesmerizing, they typically occur near where the sun appears—making direct observation potentially hazardous. This captivating event not only highlights the beauty of atmospheric optics but also serves as a reminder of nature’s fleeting artistry.
As interest in such weather phenomena continues to grow, it’s likely that more people will take to the skies or their smartphones to capture similar moments. Iridescent clouds may not be new to meteorological study, but their impact on those who witness them remains profound.
