How to See Sunspots with Your Own Eyes
Briefly

As the sun approaches its peak magnetic cycle, the increase in solar activity brings heightened occurrences of solar storms, which can lead to spectacular auroras visible on Earth.
Sunspots, the dark blemishes on the sun's surface, can vary greatly in size, with some being so large that they are visible to the naked eye with adequate protection.
The sun's core reaches temperatures of 15 million degrees Celsius, leading to a process where heat strips electrons from atoms, creating a plasma state of matter.
The movement of electrons inside the sun generates magnetic fields, and the convection processes observed are akin to hot air balloons, where hot air rises and cool air sinks.
