The next supermoon won't be until 2020 - so be sure to watch it one way or another!
The lunar event is the last of three back-to-back supermoons, with the Worm Moon being so called because it occurs at the end of winter in the northern hemisphere.
"Traditional and Native American names for each full moon of the year are derived by how they helped to track the seasons".
"Interestingly enough, the March full moon will also be the first full moon of meteorological spring [which began on March 1]", continues Samuhel.
The rare sight will be visible in Australian skies from around 7pm Thursday night (AEST, so 8pm for those in AEDT states), but its largeness and brightness will peak closer to midnight. The first day of spring 2019 for those in the Northern Hemisphere is Wednesday, March 20. During this process, the sun is shining directly over the earth's equator, bathing the earth's northern and southern hemispheres in almost an equal amount of sunlight. The March equinox marks the moment the sun crosses the celestial equator - the imaginary line in the sky above the Earth's equator - from south to north and vice versa in September.
The actual equinox was scheduled to occur at 5:58 p.m. EDT Wednesday for those in the Northern Hemisphere and in the Southern Hemisphere, the fall season was set to begin. The last time that happened was in March 2000, according to EarthSky. The first was on January 21, and the second - the biggest and brightest supermoon of 2019 - was on february 19.
Yes, I'm thrilled to report that things are verifiably brighter, because today marks the Vernal Equinox.
No matter what timezone you're in, look out for the supermoon at 9:43 pm ET on Wednesday. Equinox is derived from the Latin aequus, which means equal, and nox, the term for night.
The date of the equinox changes from year to year to account for the fact that the Earth doesn't take exactly 365 days to make a complete revolution around the sun.
