It's the lowest level of solar activity we've seen since 2011, even though the Sun is only halfway through its 11-year cycle, and five years off its solar minimum. But for some reason, it seems to have gone quiet a lot earlier than usual.
Solar activity is measured by the amount of sunspots on the Sun's surface. Sunspots are those visible dark spots on the Sun that indicate areas where the magnetic field is very strong - thousands of times stronger than Earth's magnetic field.
Eventually, all of this magnetic energy is released in the form of powerful solar flares, which are brief and incredibly intense blasts of high-energy radiation. When these solar flares are aimed at Earth, they can interrupt radio communications, and cause spectacular aurorae further from the poles than usual.
