Spring Equinox 2020 Lowell ObservatoryHere in Great Falls Virginia on the day of the Spring Equinox, March 19th, it's a rainy day.  Perhaps that helps us want to stay inside with all of the travel and meetings restrictions imposed because of the Covid-19 virus.  However, astronomical events aren't deferred because of human and biological issues.  Late today the sun crosses the celestial equator and heralds in Spring.  You can observe this event remotely thanks to Lowell Observatory in Arizona.  Lowell Observatory will begin Live Streaming the event starting at 9pm EDT. "The spring equinox in 2020 occurs on Thursday, March 19 at 8:49pm MST/PDT (3:49am GMT), when the Earth's axis is exactly perpendicular to an imaginary line drawn between the Earth and Sun. On the equinox, the Sun rises due east, and it sets due west, no matter where you are on the Earth."
