A video of a dramatic cloud formation over Islamabad, Pakistan, has gone viral on social media, with many users linking it to the highly anticipated “Blood Moon” lunar eclipse. Experts, however, say the spectacle has nothing to do with the celestial event.
The footage, widely shared on September 6, shows a towering, illuminated cloud above the capital city’s skyline. Viewers described it as a “heavenly sign” appearing just hours before the world prepares to witness a rare astronomical event — the total lunar eclipse, known as the Blood Moon.
Anticipation of a rare lunar event
On the night of September 7–8, the Earth will align perfectly between the Sun and the Moon, casting a shadow that will turn the Moon a reddish colour. The event, according to astronomers, will be visible to around 77 percent of the world’s population.
The eclipse is set to begin at 21:11 GMT and will last for approximately 82 minutes. During this period, stargazers across Asia, Europe, Africa and parts of the Americas will be able to witness the spectacle.
Social media users in Pakistan were quick to draw connections between the extraordinary cloud formation and the eclipse, suggesting that the two were somehow linked. Captions accompanying the viral clip described the sight as a prelude to the Blood Moon.
Experts weigh in
Meteorologists, however, dismissed the claims, saying the formation was a cumulonimbus cloud — a type of cloud associated with thunderstorms.
“These clouds can rise up to 12 miles into the atmosphere and often produce lightning within them,” explained a weather analyst based in Islamabad. “The flashes of light seen in the video were a result of storm activity, not a cosmic event.”
Cumulonimbus clouds are not uncommon in Pakistan during the late monsoon season. They can develop rapidly and often dominate the skyline with their towering structure. When illuminated by internal lightning, they can appear even more dramatic, sparking fascination among onlookers.
Social media speculation
Despite expert clarification, speculation online continued, with some users posting the clip alongside hashtags related to the Blood Moon. Others shared it as a sign of nature’s beauty, regardless of its scientific explanation.
“It was breathtaking,” wrote one user on X, formerly Twitter. “Even if it was just a storm cloud, it felt like something special was about to happen.”
The science behind the Blood Moon
The Blood Moon occurs when sunlight is refracted through Earth’s atmosphere during a total lunar eclipse, filtering out blue light and casting a reddish tint on the Moon’s surface. The phenomenon has long been a subject of folklore and superstition, but scientists emphasise that it is a predictable and natural occurrence.
As millions prepare to witness the eclipse, experts urge viewers not to confuse atmospheric events with celestial ones. “The timing may have been coincidental, but the cloud in Islamabad was purely meteorological,” one astronomer said.
For Pakistanis, however, both the storm cloud and the Blood Moon serve as reminders of the wonder and unpredictability of the natural world.
