Spring arrives March 20, along with ‘supermoon’
It’s been a lovely spring so far – the daffodils and forsythia are blooming, the birds are singing. But don’t be fooled: It’s actually still winter.
Spring doesn’t officially arrive until the vernal equinox, which will occur locally at 5:58 p.m. Wednesday, March 20.
The equinox marks the moment when the sun crosses the celestial equator, giving us a day and night of equal length. Then the amount of daylight will continue to grow each day, until we reach the summer solstice – the longest day of the year – on June 21.
But this year’s vernal equinox is special, because it will be followed just a few hours later by a full moon – in fact, the third and final “supermoon” of 2019. “Super” refers to the fact that it’s closer to Earth than usual, which means it will appear larger and brighter than a typical full moon.
How common is it for a full moon to occur on the spring equinox? Well, the last time it happened was in the year 2000, and it’s not set to happen again until 2030.
So enjoy the beauty of this full moon, and don’t be deterred by its rather disgusting nickname. Yes, the March full moon is known as the “Worm Moon,” allegedly because this was the time of year when the ground thawed out and the earthworms emerged from hibernation – a less delightful harbinger of spring.
