Kwak Jae-sik “Aurora in Korea? Observed in Yeongcheon in 2003” (Cheolpaem)

Kwak Jae-sik appeared on ‘Kim Young-cheol’s Power FM’

In the SBS Power FM ‘Kim Young-cheol’s Power FM’ broadcast on the 16th (Tuesday), Kwak Jae-sik, a professor of environmental and safety engineering at Soongsil Cyber ​​University and a science fiction novel writer, talked about ‘Science Convenience Store’ In the corner, listeners’ curiosity was resolved and interesting science stories were told.

On this day, DJ Kim Young-cheol introduced a listener’s question, “Writer, if you had a fan club, what would you like the name of the fan club to be?”and Kwak Jae-sik said, “It brings back old memories. In the early days of my career as a writer, in 2009, I surprisingly held a fan meeting. At the time, in a community called Dunage Bulletin Board, the nicknames were ‘Madame Curie’, ‘Handsome Nurse’, and ‘Su’ These people took the lead and gathered 20 to 30 people for a fan meeting. If you were to create a fan club name, take the nicknames of the people who arranged the fan meeting at the time and use it as ‘Miquisu’ “I wonder what it would be like to do something like this,” he replied.

Next, Kwak Jae-sik announced January’s ‘Earth’ Aurora was introduced as a theme.

When Kim Young-cheol asked, “Why do auroras occur?” Kwak Jae-sik responded, “It is a phenomenon in which electrically charged debris flying from the sun reacts when it touches the air and emits light. Why does the sun shine like that? It emits light and heat while producing a phenomenon called hydrogen nuclear fusion, which has a similar effect in principle to a hydrogen bomb. At that time, not only light and heat but also various miscellaneous substances are sent into outer space. The debris falling from the sun is called the solar wind because it resembles the wind blowing toward the Earth and spreading into space. Although it is weaker than the actual wind, the material flies in an electric state and moves quickly, so it can cause various reactions when it falls to the Earth. At this time, if the magnetic force is strong, it tends to emit more visible light. There is a large magnet inside the Earth, and since the South and North Poles act like the N and S poles of the magnet, it is said that the aurora phenomenon, which produces light when solar wind touches the South and North Poles and touches the air, is more visible.” ; explained.

Afterwards, Kim Young-cheol asked, “Can we see the Aurora in Korea?” and Kwak Jae-sik said, “Acts of the Joseon Dynasty.” According to a record on November 3, 1701, in the lunar calendar, something like a red cloth appeared in the sky of Busan, and it seemed to be unfolding and moving. What did people from the Joseon Dynasty see in 1701? Did you see an alien spaceship? Did a jellyfish-like space monster briefly appear in Busan? It is worth speculating that perhaps the people of the Joseon Dynasty who saw the aurora thought it was so strange that they did not know what it was and recorded it. In fact, if modern scientists decide to conduct research and look through historical records from the Joseon Dynasty or Goryeo Dynasty, they can see that phenomena presumed to be aurora occasionally appeared in Korea as well. “Scientists believe that if an aurora appears in the Korean Peninsula, there is a high probability that it will appear in red.”

Kwak Jae-sik said, “There are no cases of officially scientific observation in modern times,”and “Aurora was observed by our country’s measuring equipment at Bohyeonsan Observatory in Yeongcheon-si, Gyeongsangbuk-do at around 3:40 a.m. on October 30, 2003. There was an enemy. At this time, the color appeared red as expected. So, it has been scientifically confirmed that aurora can sometimes appear on the Korean Peninsula,” he said. “When you think of Yeongcheon, grapes and onions are famous, but I think you could say that Yeongcheon is the only city in Korea where aurora comes.” He added.

‘Kim Young-cheol’s Power FM’ is broadcast every day from 7 am to 9 am on SBS Power FM, and can also be listened to through the PC and smartphone application ‘SBS Gorilla’.
