The Sun is approaching the peak of its 11-year cycle, as indicated by the video taken by NASA’s solar monitoring satellite on April 23, as the recording shows four solar flares at the same time, which may cause geomagnetic storms on their way to Earth, but there is no need to worry about it.
During this phase of the Schwabe cycle, sunspots and coronal mass ejections (CMEs) occur regularly, sometimes causing spectacular auroras and radio blackouts on Earth. On April 23, NASA’s Solar Dynamics Observatory (SDO) satellite managed to record four solar flares at the same time, which happens quite rarely.
Magnetic loops in the outermost part of the sun, called the corona, can connect sunspots or filaments. When one explodes, it creates an instability in these magnetic forces that can trigger other eruptions, so multiple solar flares can happen at the same time. Scientists aren’t yet sure if the sun has reached solar maximum yet, but if not, it may soon.
