At 11:27:28 UT on May 29, 2020, the Solar Ultraviolet Imager (SUVI) aboard GOES-16 (GOES-East), captured the largest solar flare, or eruption of radiation on the surface of the sun, since October 2017. The flare can be seen on the upper left side of the sun’s horizon. The sun is a pretty turbulent place, and its massive, complex magnetic field causes giant solar eruptions such as solar flares and coronal mass ejections. This field is large enough to encapsulate space far past the edge of the planets and helps protect the planets within it from harmful cosmic particles, similar to how the Earth’s magnetic field protects it from much of the sun’s radiation. We can see manifestations of the magnetic field in the form of sunspots, which are cooler, dark areas on the sun’s surface which mark regions where magnetism is the strongest. Solar flares are most often associated with these regions. Flares are classified according to their strength and range: B, C, M, and X are ordered from smallest to largest, with each letter representing a ten-fold increase in energy output. This particular flare was a relatively small M-class flare. Although X-class flares are the most dangerous, with the potential to damage satellites, communication systems, ground-based technologies, and power grids, M-class flares can cause brief radio blackouts at the poles and minor radiation storms that can potentially harm astronauts beyond the planet’s atmosphere. This is why it’s important for scientists to constantly monitor the sun’s activity for changes. The sun’s solar cycle spans roughly 11 years, and when the sun reaches its maximum activity, these flares become larger and more frequent, which increases the chances that one may affect the Earth. Although it’s difficult at this point to say if the sun’s activity is beginning to ramp up, scientists will continue to watch the sun closely over the next several months to see what happens next. <a href="https://www.nesdis.noaa.gov/content/largest-solar-flare-2017-spotted-sun" rel="noreferrer nofollow">www.nesdis.noaa.gov/content/largest-solar-flare-2017-spot...</a> |
