We used to think the beginning of the spring season in the Northern Hemisphere and the autumn season in the Southern Hemisphere. began on March 21 but that thinking has changed.

The equinox occurs when day and night have equal amount of time with 12 hours each. But in the spring, there are a few more minutes of daylight at the mid-temperate latitudes on equinox day, March 19, this year. However, the exact time of the March equinox is 11:06 EDT.

Weather and astrological sites such as EarthSky and the Old Farmer’s Almanac estimate 2-2 1/2 minutes more of daylight. But location does matter. The difference can be 8-10 minutes.

For sunrise and sunset in your are visit Almanac rise and set which is currently set for Chicago, IL.

As to when, sunrise is the time that the edge of the sun first touches the eastern horizon. Sunset is when the last edge of sun touches the western horizon.

March supermoon marks spring

Look up the night of March 20-21. There will be a supermoon. A supermoon is a full moon (or new moon but you don’t see the new moons even if they are super) that just about coincides with when the moon’s egg-shaped orbit puts it at its perigee, the closest point to earth during that month’s orbit. It happens Tuesday.

This supermoon also coincides with the Northern Hemisphere’s spring equinox. In the Southern Hemisphere it is autumnal equinox. Vacationers take that opposite season into consideration when planning a trip.

You’re right if you think you just saw a suspermoon. The closest supermoon of 2019 was Feb. 19, the middle supermoon of a series of three that occurred Jan. 21, happened again in mid February and ends with the one this week March 20-21.

But this one comes on what is the spring equinox north of the equator and fall equinox south of the equator. Also called the vernal equinox, it is when the Sun is exactly above the equator during the Earth’s axis movement from south to north.

Until this date, the Sun rises and sets somewhat south of the equator. After this date it rises and sets more to the north of the equator.  You will likely start noticing the sun beginning to shine on a different part of your property.

What else can you expect? The moon will look larger, mostly as it rises around sunset which is a moon illusion. But this supermoon will also look brighter and ts pull also has a tidal impact. Some people might even complain of sinus headaches.

Of course you will see monthly full moons this year but the one coming up in mid-March is the last of the 2019 supermoons so mark it on your calendar.
