News sources are picking up on the fact that the solar maximum is approaching in July 2025, with an increase in the number of sunspots. Sunspots often appear in pairs with different magnetic polarities. They become more prevalent every 11 years (solar cycle) and they migrate through latitudes, moving closer to the equator as the solar cycle progresses.
SpaceWeatherLive tracks solar activity and reports that the Sun has erupted from February 1st through the 17th with some days featuring multiple flares. That includes three flares of the second-most powerful category: an M1.4 on February 12; an M1 on February 14; and an M1.3 on February 15.
Solar flares happen because of the constantly moving magnetic fields in the Sun's atmosphere. The frequency of solar flares coincides with the Sun's 11-year cycle. When the solar cycle is at a minimum, fewer solar flares are detected. Flares increase in number as the Sun approaches the maximum part of its cycle.
The Sun's magnetic field has a north pole and a south pole. About every 11 years, the Sun's magnetic field does a flip. The north pole becomes the south pole, and vice versa.
This flip is one feature of the solar cycle. As the cycle progresses, the Sun's stormy behavior builds to a maximum, and that is when the magnetic field reverses. Then the Sun settles back down to a minimum, only to start another cycle.
Solar storms are not unusual. An ancient solar storm happened around7200 BC when most humans lived at Earth's middle latitudes, not near the poles. Another big storm came between 775-774 BC. By then humans were more widely dispersed and yet they survived that event.
