It could erupt anytime now.
of the solar system before dying down without much to show for it. Other times though, they give out intense bursts of electromagnetic radiation, whose intensity can vary significantly.Depending on the radiation released, the National Oceanic and Atmospheric Administration classifies solar flares into five categories. Classes A, B, and C are flares of relatively low intensity, while M class is used to designate flares of moderate intensity.
Each class is further divided into the logarithmic scale of 1 through 9, except X class, which continues further. X class flares are mostly rare, but when they do occur, they tend to have high number of intensities such as one in 2003, which was estimated to be of intensity X40. The instrumentation developed so far can only accurately measure solar flares up to the intensity of X16.
Since the sunspot is pointed directly toward the Earth, we would receive the full blast of magnetic radiation. It is also possible that some of the particulate matter from the Sun be also let out along with this flare, which scientists call a coronal mass ejection . If either of these events were to occur, we would be protected by the Earth's atmosphere.
Even if sunspot AR3089 goes off without much fanfare, a large hole in the solar atmosphere is leaking out gaseous material that could send a stream of solar wind on September 4,. If a solar storm materializes, auroras could be seen in the U.S. as far south as New York and Idaho. Our Sun is now close to reaching the peak of its 11-year solar cycle. So, instances of powerful solar storms are expected to increase in the near future.
