When you think about the year 2020, it is going to be worse. According to the spaceweather.com report, there is a massive sunspot on the Sun that will be turning towards our planet which could result in major strong flares. The sunspot AR2770, which was deducted earlier this week is expected to grow in size. there can be multiple minor flares that have been emitted by the sunspot already as it faced towards the earth. These flares have caused “minor waves of ionization to ripple through Earth’s upper atmosphere” but nothing major yet.
The main question is what is a sunspot? The sunspots are the darker and cooler areas on the surface of the sun in a region known as the Photosphere. The region reduces the surface temperature caused by concentrations of magnetic flux that inhibits convection. Sunspot usually appears in pairs of opposite magnetic polarity. The intense magnetic activities lead to the release of a great amount of energy that erupts out in the form of solar flares and storms known as coronal mass ejections (CME).
if this sunspot which can be up to 50,000 kilometers in diameter may release a huge amount of energy which in turn will lead to solar flares.
These eruptions may lead to solar flares and storms. These flares can have a major effect on affect radio communications, Global Positioning Systems (GPS) connectivity, power grids, and satellites. Solar flares are explosions on the surface of the Sun that release an enormous amount of energy, equivalent to a trillion ‘Little Boy’ atomic bombs exploding at the same time. While solar flares are huge explosions on the sun, a CME is an ‘enormous bubble of plasma’ expelled by the sun.
A clear picture of the AR2770 has also surfaced which gives a better idea into the current phenomenon. It was captured by an amateur astronomer Martin Wise from Trenton, Florida. The size of the “primary dark core” is about as wide as Mars and it has several “Spotlets” on its surface, which are similar to the craters on the surface of the moon. scientists developed a new model that can successfully predict seven of the Sun’s biggest flares from the last solar cycle, out of a set of nine with the help of NASA’s Solar Dynamics Observatory. With wise captured the dark sunspot using an 8-inch telescope with safe solar filters and its dimensions make this sunspot “one of the largest sunspot groups of the current Solar Minimum.”
According to the National Oceanic and Atmospheric Administration (NOAA), the CMEs can result in ‘fluctuations of electrical currents in space and energize electrons and protons trapped in Earth’s varying magnetic field’. Solar flares caused by these CMEs can also trigger intense light in the sky, called aurora. Simply, we can say Massive sunspot is turning towards Earth this can result in major solar flares that can affect electrical systems
