It is expected to arrive in 2024 or 2025, and the number of sunspots has already exceeded previous predictions. During this peak, the planet could face CMEs, solar flares, solar storms, and other particles with potentially disastrous consequences. In a new development, NASA’s Solar Dynamics Observatory (SDO), which carries a full suite of instruments to observe the Sun, has recently revealed that Earth could be in the firing line of a sunspot and dangerous solar flares could be hurled out that could have the potential to wreak havoc. We're now on WhatsApp. Click to join. ## Dangerous sunspot According to a report by spaceweather.com, NASA’s Solar Dynamics Observatory (SDO), forecasts that a region on the Sun’s surface, termed Sunspot AR3451, has a “'beta-gamma” magnetic field that could trigger solar flares. There is a chance for M-class solar flares to be hurled out and hit Earth soon. Also read click here. It states, “Sunspot AR3451 has a 'beta-gamma' magnetic field that harbors energy for M-class solar flares”. For the unaware, solar flares are classified according to their strength on the logarithmic scale, similar to how earthquakes are measured. The smallest ones are A-class which occur at near background levels, followed by B, C, and M, while X-rated flares are the strongest. ## Sun’s magnetic poles disappear According to a report, the Solar Dynamics Observatory has also observed that the Sun’s North and South poles are disappearing. Although it would’ve been followed by a series of calamities if it were to happen on Earth, the disappearance of magnetic poles is considered natural during the peak of the solar cycle. Before the year ends, the poles are expected to completely reverse the Sun’s global magnetic field as we approach the peak of Solar Cycle 25. Todd Hoeksema, a solar physicist at Stanford University told SpaceWeather, “In fact, it's routine. This happens every 11 years (more or less) when we're on the verge of Solar Maximum."
