This animation shows daily snapshots at 06:00 UTC from Meteosat-12’s Flexible Combined Imager, tracking the terminator (the line between day and night) as it swings from the December solstice, through the March equinox, to this week’s June solstice.   In December, the terminator cuts diagonally: high northern latitudes are deep in darkness while the Southern Hemisphere basks in long days. By March, it runs almost perfectly vertical - day and night in balance everywhere on Earth. By June, the tilt has flipped: the Arctic is bathed in continuous light while southern latitudes draw the short straw.
