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, called Solar Maximum, every 11 years. The featured video shows on the left a month in late 2019 when the Sun was near Solar Minimum, while on the right a month in 2014 when near Solar Maximum. The video was taken by NASA's Solar Dynamic Observatory in far ultraviolet light. Our Sun is progressing again toward Solar Maximum in 2025, but displaying even now a surface with a surprisingly high amount of activity.

It’s a good thing that changes like this can’t effect our weather. [/s]
Solar maximum - DAY
Solar minimum - Night.....................
What if Earth was always on the night time side of the sun? Have any government scientists thought about that?
Yeah propagation on the HF ham radio bands is getting good!
You get the max for the minimum at t.j Maxx.
The “Explanation” fails to point out that the comparison solar maximum sequence in 2014 was a low-power equatorial maximum. Currently the sun is approaching the maximum of the following polar cycle where sun spot activity happens more at the sun’s poles where the earth is less affected.
This lowered solar output in earth’s direction has been driving the recent droughts and heat waves through curtailed Pacific Ocean circulation.
