Ancient texts help forecast ... the solar storm

Writers hundreds of years ago recorded events related to solar storms, Japanese scientists studied two episodes of Meigetsuki and Song Shi - covering periods from the 10th century. by the 14th century. This could help us prepare for the great solar storms in the future.

Scientists have found evidence in ancient Japanese and Chinese literature that has described descriptions of cosmic weather phenomena for centuries and can help us prepare for the Sun storm. big in the future.

Ancient texts are a valuable source of information in studying storms from the past.

Because the Sun storms are capable of causing widespread disruption and harm on Earth, they do not leave any physical traces for scientists to study, that's why Why historical documents can be invaluable in discovering the past existence of these invisible storms.

"Combining literature and observing space, we have discovered a clear model in solar activity and astronomical events , " said space scientist Hiroaki Isobe from Kyoto University, Japan. "In this day and age, big solar storms can significantly disrupt the grid and satellite. We are now very sensitive to solar-related events, and insight into the through historical documents that allow us to better predict and prepare for the future ".

In Meigetsuki, Japanese poet Fujiwara Sadaie reminds him of reddish and white in the night sky on February 21 and 23, 204 - understood as a sign of a storm from attacking Earth at that time. ."Reddishness appears in the north and northeast , " he wrote. "It's like a distant mountain. It's a very terrible image."

Magnetic storms are derived from explosions on the Sun's surface.

Meanwhile a large sunspot, a sign of intense activity on the Sun, was also recorded at the same time in Song Shi."We found that about 10 aurora incidents lasted for this period," said historian Hisashi Hayakawa . "When these days are compared to radioactive carbon data from wood grain, we record a decrease in the level of carbon-14 (only the increase of solar activity) at the same points."

These texts have set the stage for researchers to build a chronology of cosmic weather activities, and also revealed that aurora will be more common at the maximum stage of the Facial cycle. heaven - when the sun and radiation activity happens - all of that data gives us a better base in predicting magnetic storms.

Solar storms occur when explosions of particles from the Sun affect oxygen and nitrogen in the Earth's atmosphere and at the same time the Earth's magnetic field is affected. Particularly serious Solar events, known as diurnal eruptions (CMES), can cause major problems on our planet.

A large solar storm today can seriously affect all satellites, GPS, internet, and other communications systems.

The most recent big storm was in 1859 that caused electric shocks and clouds of light at night, but the consequences will certainly be much greater in today's era due to scientific advances. technique we have.

Compared to the past, the effect of a storm from the present will be much greater.

Another problem is that no one really knows when the next serious storm will hit Earth, which is why scientists are looking for predictions based on any evidence or idea. Which exam is found. Researchers are looking for ways to see if there are any more ancient texts that may be holding clues that we can use to map out the Sun's history and cosmic weather events. abnormal.

Content that has previously been overlooked for scientific or practical content may be available but has not yet been explored useful information in it, and any identified Sun storm model can Help scientists prepare for the same phenomenon in the future. Previously, Fujiwara Sadaie's works were "not really valuable for scientific research" , according to Tsuneyo Terashima, deputy director at the National Institute of Japanese Literature, who also helped with research. "Now we realize that Meigetsuki actually provides a clear and accurate amount of information about the natural conditions of this period."
