The sunspot labeled AR2770 could be cause for some concern as it is expected to grow in size according to spaceweather.com. Some minor solar flares have been emitted by this sunspot already. Though this has caused no reason for alarm.
However, if this sunspot, which can be up to 50k kilometers in diameter, may release a huge amount of energy in the form of solar flares. The phenomenon called Coronal Mass Ejection can cause solar storms and flares whose energy can reach all the way to earth and have a major effect on radio communication, GPS, satellites and even power girds.
NOAA stated that CMEs can cause changes in electrical currents in space which varies the Earth’s magnetic field. CMEs can also cause auroras.
A sunspot is a dark part of the sun that appears cooler than the other parts and contains electrically charged gases which in turn can generate great magnetic forces. Solar flares are the result of changes in the magnetic fields in the sunspots which cause huge explosions—the flares’ radition can disrupt many different types of technology on earth. One solar flare can be as powerful as one “Little Boy” atomic bomb like the ones dropped on Japan in 1945 by the United States.
