The biggest sunspot on the face of the sun in more than two decades unleashed a major flare on Friday the fourth intense solar storm from the active star in less than a week. The solar flare reached its peak at 5:41 p.m. EDT (2141 GMT), and triggered a strong radio blackout at the time, according to the U.S. Space Weather Prediction Center. The flare erupted from a giant active sunspot known as AR 12192 and was classified as an X3.1-class solar storm, which is one of the most powerful types of solar storms on the sun, however, it is not the first time the sunspot has occurred. Sun flares are regions of the sun forged by shifting magnetic fields that are cooler than their surrounding solar material, giving them their dark, blemish-like appearance.

The Sun has hurled solar flares towards earth, threatening disruption of some of the satellite communication links. The size of the sunspot is the largest seen for any of the flares in the last 24 years. The sunspot is located in the region with the potential of producing flares and coronal mass ejections. The coronal mass ejections are defined as massive bursts of solar winds and magnetic fields that go above the solar corona and eventually enter space. They do not pose any danger alone, but are certainly a reason to worry in a group.

As per the warning of Spaceweather.com, the effect on earth is likely to increase in the coming days since earth is right in front of the active region causing powerful explosions. Forecasters at the NOAA Space Weather Prediction Center have revealed that the main communication impact due this event is currently seen over the Pacific Ocean. “This is the fourth substantial flare from this active region since Oct. 19,” NASA spokesperson Karen Fox wrote in a status update.
