A breathtaking iridescent cloud over Bogor, Indonesia, went viral last week, captivating viewers with its stunning display of colors. This rare atmospheric phenomenon is a striking example of cloud iridescence.
Ida Pramuwardani from the Indonesian Meteorology, Climatology, and Geophysics Agency (BMKG) noted, “The phenomenon seen in the video is a common occurrence in the atmosphere and is related to atmospheric optics.” This insight provides context for the excitement surrounding the event.
Residents of Jonggol in Bogor were fortunate enough to witness this spectacle, which can appear in hues of pink, green, and blue. The colors change rapidly and can disappear just as quickly—an ephemeral beauty that adds to its allure.
The pileus cap—an umbrella-shaped cloud—was crucial for this occurrence. It provided the consistent droplets necessary for creating iridescence. This phenomenon is not new; iridescent clouds have been documented since at least 1911.
Interestingly, similar clouds have been reported in Malaysia, Vietnam, and Singapore in recent years. The BMKG confirmed that the rainbow clouds observed were genuine and natural, dispelling any doubts about their authenticity.
Iridescent clouds can sometimes be confused with nacreous clouds or coronae. However, their unique formation through sunlight diffraction off ice crystals sets them apart.
The viral nature of this event sparked curiosity among locals and social media users alike. Such weather phenomena remind us of the beauty found in our atmosphere—if we take a moment to look up.
As these displays of atmospheric optics continue to intrigue observers worldwide, they also serve as a reminder of nature’s wonders that often go unnoticed.
