One of the brightest heralds of spring makes its appearance this week.
The March full moon, known as the worm moon, will be at its peak at 3:18 a.m. ET on Friday, March 18, according to NASA. It will appear full through Saturday morning.
(See more below for, er, how it got its name.)
This moon will appear larger to viewers because of the “moon illusion,” according to the Old Farmer’s Almanac. This occurs when the moon is near the horizon and our eyes compare the moon’s size to trees, buildings or other earthly objects. By comparing these reference points to the moon, our brain tricks us into thinking the moon is bigger.
Southern Native American tribes named the worm moon after the earthworm casts — essentially feces — that emerged as the ground thawed at winter’s end, according to NASA.
You don’t have to be a hunter to enjoy the Hunter’s Moon tonight, Oct. 20. More below from EarthSky. Happy viewing and/or hunting.
“The Hunter’s Moon is the full moon after the Harvest Moon. It usually falls in October, but, if not, it falls in early November. [ . . .] It’s a characteristic of the Hunter’s Moon to rise around the time of sunset for several evenings in a row, as if this month has more than one full moon.”
Hunter’s Moon
Hunter’s Moon October 20, 2021
The Hunter’s Moon is the full moon after the Harvest Moon. It usually falls in October, but, if not, it falls in early November. October 2021’s full moon – the Northern Hemisphere’s Hunter’s Moon – will be 100% lit on October 20 at 14:56 UTC; translate UTC to your time. On October 21, and even on October 22, you might glimpse a full round moon ascending in the east in early evening. It’s a characteristic of the Hunter’s Moon to rise around the time of sunset for several evenings in a row, as if this month has more than one full moon.
Eastern Australia and New Zealand will see the full moon on October 21. It’s not a Hunter’s Moon for the Southern Hemisphere because it’s spring in that hemisphere now. So the full moon has different characteristics.
Every full moon has a slew of nicknames, and most are tied to months of the year. But some moon names, such as the Harvest and Hunter’s Moons, are tied to seasons. The Harvest Moon is the full moon closest to the September equinox, or autumnal equinox for the Northern Hemisphere. The equinox is typically September 22 or 23. So most Harvest Moons come in September. But, every three years, the Harvest Moon falls in early October and the Hunter’s Moon in November.
In North America, the Harvest Moon was a time when the bright moon meant farmers could stay out later, working in their fields, gathering in the crops before the first freeze. After the harvest, farmers would turn to hunting deer and other animals to bolster their food stores before winter. The light of the full moon would let them hunt into the evening hours. So today we have a Hunter’s Moon.
The West’s Hunter’s Moon is sometimes celebrated as Kartik Purnima in India. In 2021, the dates vary a bit. The festival will come around the November full moon (night of November 18-19 in India). Swami Krishnananda in Ranchi, India, captured this photo during Kartik in 2017. Thank you, Swami Krishnananda!
What makes this moon special?
Nature is particularly cooperative around the time of the autumn equinox to make the fall full moonrises unique. On average, the moon rises about 50 minutes later each day. But when a full moon happens close to the autumnal equinox – either a Harvest or a Hunter’s Moon – the moon (at mid-temperate latitudes) rises only about 30 to 35 minutes later daily for several days before and after the full moon. The reason is that the ecliptic – or the moon’s orbital path – makes a narrow angle with the evening horizon around the time of the autumn equinox.
The result is that there’s a shorter-than-usual lag time between successive moonrises around the full Hunter’s Moon.
Early evening moonrises make every Hunter’s Moon special. Every full moon rises around sunset. After the full Hunter’s Moon, you’ll see the moon ascending in the east relatively soon after sunset for a few days in a row at northerly latitudes.
If you’re in the Northern Hemisphere, look for the moon to be bright and full-looking for several nights from around October 19 to the 22. Around all of these nights, you’ll see a bright round moon ascending in the east in the evening hours.
This Halloween’s Blue Moon Will Bring a Rare Treat to the Skies
For the first time since World War II, people in all parts of the world will be able to see the Oct. 31 display.
Halloween may look different this year due to coronavirus restrictions, but at least we can enjoy a spooky spectacle in the sky: a rare second-in-the-month full moon to cap off a month of glorious skywatching.
The full moon that will be visible on Oct. 31 is called the blue moon because it’s the second full moon of the same month — following the harvest moon of Oct. 1 through Oct. 3. And in a rare treat, the 2020 Halloween full moon will be visible to the entire world, rather than just parts of it, for the first time since World War II.
“When I was teaching, my high school students thought a full moon occurred every Halloween,” astronomy educator and former planetarium director Jeffrey Hunt told me. Not quite, though pop culture decorations sure make it seem that way. The last Halloween full moon visible around the globe came in 1944, he said. He’s written about the event on his web site, When the Curves Line Up. There was a Halloween full moon for some locations in 1955, but that didn’t include western North America and the western Pacific, Hunt says.
While this year’s Halloween full moon will be visible in all parts of the globe, that doesn’t mean every single citizen will have a view. Residents across both North America and South America will see it, as will Africa, all of Europe and much of Asia. But while Western Australians will see it, those in the central and eastern parts of the country will not.
Know time zones well? “Every time zone has it except those east of (GMT) +8 time zones if they have daylight time, or (GMT) +9 with no daylight time,” Hunt says.
Want to see the Halloween full moon? It’s so bright at the full phase it doesn’t matter if you’re in a crowded city or out on the farm. And you don’t need pricey equipment.
September’s full Moon is coming up, the so-called “Harvest Moon,” which is the full Moon nearest to the autumnal equinox (September 23rd). The arrival of this year’s Harvest Moon will depend on which time zone you happen to live in. If you live in the Eastern Time Zone, the moment the Moon turns full will occur just after midnight—at 12:33 a.m. on Saturday, the 14th. But if you live elsewhere in the country—in the Central, Mountain, or Pacific time zones—the moment that the Moon turns full comes before midnight on Friday, the 13th!
Split Time Zone Full Moon: How Often Does This Happen?
Interestingly, the last time this happened—June 13, 2014—it was the reverse of what will happen this month. It was a Friday the 13th full Moon solely for the Eastern Time Zone, with the Moon turning full just after midnight; for the rest of the country, the full Moon was the day before, on Thursday, the 12th. Nationwide we haven’t had a Friday the 13th full Moon since October 13th, 2000, and it won’t happen again until August 13th, 2049!
It has been calculated that to have a full Moon occur on the 13th day of a particular month, and for that day to be a Friday, it is (on average) a once in 20-year occurrence!
Why The Harvest Moon is Unique
What sets this upcoming full Moon apart from the others is that farmers, at the peak of the current harvest season, can work late into the night by this Moon’s light. The Moon rises about the time the Sun sets, but more importantly, at this time of year, instead of rising its normal average 50 minutes later each day, the Moon seems to rise at nearly the same time each night leading up to when it’s full. For example, between September 12th and 14th, the rising of the Moon comes, on average, less than 27 minutes later each night, thus providing light for the farmer to continue gathering crops, even after the Sun has set.
The reason for this seasonal circumstance is that at this time of the year, the path of the Moon through the sky is as close to being along the horizon as it can get. Thus, from night to night the Moon moves more horizontally than vertically and thus rises sooner from one night to the next.
A Micro Moon?
To add to this full Moon “madness,” this upcoming full Moon very nearly coincides with apogee—that point in its orbit which places it at its greatest distance from the Earth: 252,100 miles away. Remember last February, when the full Moon coincided with perigee, its closest point to Earth? The Moon was more than 30,000 miles closer and was accordingly branded a “Supermoon.”
But this month’s full Moon will appear about 14 percent smaller, leading some to call it a “Micro” Moon.
It is almost certain that many will claim that this year’s full Harvest Moon indeed appears to be smaller than usual. But the truth of the matter is, that without knowing in advance whether a full Moon of a given month might be branded either “Super” or “Micro,” the appearance of our natural satellite to most really doesn’t look all that much different.
Here’s hoping for clear skies so you can get outside an enjoy it!
December’s full moon will coincide with the 2018 winter solstice.
The winter solstice, falling on December 21, 2018, will mark the shortest day of the year as well as a full moon in the night sky. The upcoming full moon named the Cold Moon or the Long Night Moon will be visible during the longest night of the year.
The two events don’t perfectly align. The peak full Moon will occur on December 22 at 12:49 p.m. EST while the winter solstice falls a day earlier on December 21. However, to the typical person viewing the moon, it will appear full for several days.
The winter solstice marks a transition period where days begin getting longer in the Northern Hemisphere and shorter in the Southern Hemisphere. The evening of the winter solstice will be the longest of the year for the Northern Hemisphere. This is because Earth’s poles create a maximum tilt away from the Sun in the Northern Hemisphere and maximum tilt toward the Sun in the Southern Hemisphere.
Winter solstice occurs in December for the Northern Hemisphere and June for the Southern Hemisphere.
The 2018 winter solstice will be accompanied by what NASA notes as the Cold Moon or the Long Night Moon. The names originate from the Native Americans, who marked December’s full Moon as the beginning of the coldest part of the year. Also, the Long Night Moon is named after the longest night of the year on the winter solstice.
How often do these events coincide, where the winter solstice is adorned by a full moon? The last time it occurred was in 2010 and the next event will not be until 2094. On December 21 you will also be able to see Mercury and Jupiter in conjunction in the long night sky. On top of all that, the Ursid meteor shower will peak on the nights of December 21 and 22, adding shooting starts to the mix.
Don’t miss the opportunity to look up into the night sky on this winter solstice and revel in the grandeur of the full moon and the Ursid meteor shower.
