▲ The giant sunspot AR3354, seven times wider than Earth, can be seen across the Sun with the naked eye, but observers must wear eye protection. (Provided by NASA/ SDO/ Yeom Beom-seok) An all-time sunspot seven times larger than Earth appeared. It is large enough to be seen with the naked eye. But don’t forget that if you want to see it before it disappears, you’ll need to be especially mindful of protecting your eyes. The stupendous sunspot on the Sun, designated AR3354, will disappear from Earth’s view on Sunday (July 2). According to SpaceWeather.com, the sunspot has been growing ever since it appeared on June 26. Solar physicist Keith Strong, who shared an amazing time-lapse video of a sunspot crossing the sun’s surface on Twitter, said: “The new numbered sunspot AR3354 has grown rapidly over the past 24 hours. A sunspot that wasn’t there two days ago has appeared and is now Earth “If this rate of growth continues, we will see huge solar flares explode from the sunspots.” It is a phenomenon that suddenly increases and then returns to its original state within tens of minutes or hours. Not only the chromosphere, but also the area of the solar atmosphere, the corona, has a wide impact, and the effect on the earth is much greater than other phenomena. As Strong noted, sunspots not only grew in size but also in intensity. These sunspots have been found to produce gamma magnetic fields that can cause intense solar flares. The National Oceanic and Atmospheric Administration (NOAA) has predicted a 40% chance of a medium or class M solar flare on June 28 at AR3354. NOAA forecasters also added a 10% chance of an X-flare, the largest type of solar flare, on July 5. Giant sunspot AR3354, seven times the size of Earth, will be visible to the unaided eye as it crosses the sun. there is. However, observers must protect their eyes by using solar filters. According to the European Space Agency (ESA), an M-class flare could cause a brief radio outage affecting only Earth’s polar regions, and could also trigger a small radiation storm. However, X-class flares are major events that can lead to global radio outages and long-lasting radiation storms in the upper atmosphere. Sunspots are the result of intense magnetic activity on the surface of the photosphere, or sun. This can lead to flares as well as coronal mass ejections (CMEs), which are massive outflows of stellar material. However, AR3354 has not yet exploded the CME. The new sunspot, although large in size, is not expected to produce as violent activity as the Carrington Event, the most powerful solar storm ever recorded. September 1, 1859 On Sunday, several sunspots estimated to be roughly the size of Jupiter, ten times Earth’s size, detonated the CME causing a bright white flash lasting about five minutes. The blast was so powerful that amateur astronomer Richard Carrington briefly lost sight of it To see large sunspots, you must use sun filter glasses, solar eclipse glasses, or other types of certified eye protection. It is also essential to check these equipment for scratches before using them. Also, you must put on your sun glasses before looking at the sun, and look away before taking them off. Even brief exposure to the sun can permanently damage your eyes. It’s also a good idea to use dedicated solar binoculars with built-in solar filters that allow you to look at the sun and magnify the solar disk. Lee Kwang-sik, science columnist joand999@naver.com
