Recently China’s Zhoushan city saw a blood-red sky that caused panic among the residents. Read all about the natural phenomenon that caused China’s blood-red sky below.

On May 8th, netizens shared viral snippets of the crimson sky from the Chinese social media platforms Weibo and Sina wondering the reason behind it.

Various reports also suggested that the red color was most intense in port areas of Zhoushan city.

What caused China’s blood red sky?

While speculations over China’s red sky made netizens wonder if it is a solar storm that caused a crimson sky above China, Korea, and Japan in 1770, local authorities have assured the citizens that this incident has nothing to do with solar activity.

According to local reports, the red color of the sky might have been caused by the refraction of the red light that was coming from a fishing boat harvesting Pacific saury.

A Global Times report quoted the Zhoushan Meteorological Bureau who explained, “It was foggy and cloudy in Zhoushan on Saturday and it was drizzling at the time of the red sky, which might have been caused by the reflection of light from the low-level clouds.”

The staff added, “When weather conditions are good, more water in the atmosphere forms aerosols which refract and scatter the light of fishing boats and create the red sky seen by the public.”

Experts from the space physics research team of the China University of Geosciences in Wuhan noted that the crimson sky was not caused by any anomalies of solar activity as the solar and geomagnetic activity was calm.

A look at the historical blood red sky of China

This is not the first time, China has seen a blood-red sky. According to livescience, on September 10, 1770, the sky over China, Japan, and Korea turned red and the lingering color remained for almost a week.

A number of researches have been done on this historic phenomenon trying to understand what might have been the reason. Hisashi Hayakawa, a historian and astronomer at Osaka University in Japan, and his colleagues looked into the mentions of aurora in the historic documents of Japan, Korea, and more East Asian countries.

Hayakawa noted that the long-lasting auroras were seen at low altitudes and one of the reasons behind it might be a powerful geomagnetic storm that caused them, LiveScience reported.

Hayakawa further explained, “Considering this event was so large, it would be reasonable to find more events not only in East Asia but also in other low-latitude areas,” Hayakawa said.  As a result, the team is extending its archival surveys to areas as distant as the Middle East.”
