The period of lowest solar activity in the Sun's 11-year cycle, marked by very few sunspots, minimal solar flares, and reduced solar wind intensity. During this quiet phase, the Sun's magnetic field is at its simplest configuration.
From Latin 'solaris' for solar and 'minimum' meaning smallest or least. The concept emerged alongside solar maximum as 19th-century astronomers mapped the complete solar activity cycle and recognized these periods of relative solar calm.
Solar minimum is when our star takes a cosmic nap! During these quiet periods, the Sun becomes so calm that sometimes days pass without a single sunspot visible, creating perfect conditions for cosmic rays to penetrate deeper into the solar system.
