(Thread) The official start of Spring - the Spring/Vernal Equinox - is today, at 5:58 PM EDT. This marks the time when the day-to-night line, called the terminator, is perfectly vertical from pole to pole. #SpringEquinox #FirstDayOfSpring
The Vernal Equinox is also the day of the year when day and night are most nearly equal everywhere on earth.
There will be more daylight than nighttime each day now, until the Fall/Autumnal Equinox in September.

The fairly rare alignment of a #Supermoon and Spring Equinox happens tonight too. This will be the last #Supermoon of 2019. blogs.nasa.gov/Watch_the_Skie…
A "Supermoon" is when a full Moon occurs when the moon is at closest approach in its orbit around earth. It's "Super," because the Moon will be at its brightest and largest. Clouds in your area tonight?
