Overview
- Videos from Jonggol in Bogor, southeast of Jakarta, showed a multicolored cloud that drew crowds and briefly paused traffic, with one TikTok clip topping 46 million views.
- Indonesia’s meteorology agency BMKG and independent forecasters verified the footage as genuine and said it is not AI imagery.
- Experts explain the colors come from cloud iridescence, where sunlight diffracts through very small water droplets or ice crystals.
- The display appeared brightest because the sun was partly obscured, and a towering cumulus cloud blocked part of the arc to create the “rainbow cloud” look.
- Meteorologists say the sight signals convective growth and a chance of local rain rather than an approaching large storm.
