Solar Minimum versus Solar Maximum (APOD: 2023 Dec 11) Video Credit: NASA, SDO, SVS https://apod.nasa.gov/apod/ap231211.html Explanation: The surface of our Sun is constantly changing. Some years it is quiet, showing relatively few sunspots and active regions. Other years it is churning, showing many sunspots and throwing frequent Coronal Mass Ejections (CMEs) and flares. Reacting to magnetism, our Sun's surface goes through periods of relative calm, called Solar Minimum and relative unrest, cal

Your Sun, to the max. ☀️ We’re officially in solar maximum, according to scientists who monitor and study the Sun’s natural cycles and space weather, including things like the aurora we’ve been seeing at lower latitudes. The Sun moves between low and high magnetic activity about every 11 years. At the height of the solar cycle, the Sun’s magnetic poles flip and the Sun transitions to a more active state, with more sunspots & solar storms, which can cause auroras and affect satellites and infrast
