Only recently has it emerged to make its presence known, emitting a powerful X-class solar flare that uses a radio black signal across the South Pacific.
NASA’s Solar Dynamics Observatory has a huge record to burn with the sun on Thursday (Jan. 5) at 7:45 pm EST (0045 GMT on Jan. 6). The plasma shield, which was lingering over the tea, erupted hotly sun spot AR3182 over an hour later Spaceweather.com (Opens in a new tab). Because of the sunrotation, the bright sun soon covered the Earth and could continue its explosive activity for days before.
The solar flowers are generated by size in alphabetical groups, with the X-type being the most powerful. In each class, the numbers from 1 to 10 (and beyond, for X-type flowers) indicate the relative strength of the glow. A recent flash clocked in at X1.2, a relatively weak example of the most powerful class.
AR3182 has also been linked a violent eruption on Tuesday (Jan. 3) the day sent by coronal mass ejection (CME), a huge cloud of magnetised plasma, into space. At that time the sun was hidden in the far side of the sun, and therefore the eruption presented no danger earth.

Solar flares are caused when magnetic energy builds up in the Sun’s atmosphere and is emitted in a powerful burst of electromagnetic radiation. The more powerful, M-class and X-class blooms can make smaller radio blacks from the side of the Earth facing the sun at the time of the eruption.
This is exactly what happened when a recent X1.2 solar flare sent a strong pulse of X-rays and extreme ultraviolet radiation toward Earth. Traveling at the speed of light, the radiation reaches the Earth in just over eight minutes and ionizes the upper layer Earth’s atmosphere – thermosphere – stimulated by shortwave radio black across the South Pacific.

According to Spaceweather.com, so far no CME has been observed to emerge from the area after the massive flare.
