Full moon will appear super

If the light of the moon was keeping you up last night it’s because the first full moon of spring is March 28 but looks full March 27 and March 29.

And because this spring (Northern Hemisphere) full moon is closer to earth than the ones in January and February it appears brighter and is considered by some sky watchers as a “Supermoon.”

Actually, its perigee (closest part of its orbit) is March 30 so it still will continue to appear very bright and mostly full.

Don’t worry if your area is cloudy. The full moons  in April, May and June will be even closer and will look like Supermoons.

Called  the Worm Moon, Crow Moon or Sap Moon by some native American tribes, this full moon also sets Easter, which, in 2021, is April 4.  See Tonight | EarthSky

Fun Fact:  Do you know what syzygy means?  It’s when three bodies, such as the Sun, Earth, and the Moon, are in alignment. See Time and Date for the term and alignment.

Time and Date also does an excellent job of explaining how long the moon really is fully illuminated and why due to the earth’s tilt it may not appear at total illumination, noting that the degree of illumination somewhat blends what appears to be a Full Moon and the last stage of a Waxing Gibbous Moon or the beginning of a Waning Gibbous Moon.

On NASA’s site a sidebar tells that the term “supermoon” was “coined by the astrologer Richard Nolle in 1979 and refers to either a new or full Moon that occurs when the Moon is within 90% of perigee, its closest approach to Earth.’

The site also connects the first spring moon’s names from native Americans and different religions. It notes that this weekend’s Full moon is also called the Pesach moon on the Jewish calendar, Paschal moon for Western Christianity and Medin in SRI Lanka.

The Snow Moon

According to several astronomy sources it was northeastern native Americans who dubbed February’s full moon the Snow Moon.

Given the amount of snow that covered much of the United States in February, the moon is well named. It’s also called the Storm Moon and Hunger Moon.

That orb will be lighting up the landscape Thursday, Friday and Saturday but best time to view will be Friday night from when it appears above the horizon in the east as the sun sets to midnight when it is overhead.

Some studies mentioned by EarthSky have been done on the relationship of full moons to sleeplessness from the light point of view. Hopefully, scientists will also look at the tidal pull of full moons on sinuses.

More information on the Snow Moon can be found at TimeandDate, NASA and Old Farmers Almanac.

Meteor shower and more

Look up to take your mind off 2020 politics and pandemic that still plague us on earth. The sky is endlessly interesting with bright planets such as Venus in the early morning eastern sky and Saturn and Jupiter still a cozy couple in the early twilit southwestern sky.

Now, add to the mix the Quadrantids, an annual meteor shower that has been known to send out from 50 to 100 fireballs an hour. Associated with asteroid 2003 EH1, the Quadrantids were named for the defunct constellation Quadrans Muralis.

The good news in 2021 is that the Quadrantids peak early morning before sunrise Jan. 3. Because sunrise at this time of year in the northern hemisphere is shortly after 7 a.m., the Quadrantids peak time of around 6 a.m. means you don’t have to get up in the middle of the night to catch them.

Best plan is to let your eyes acclimate to the darkish sky and look northeast where their radiant (place of origin) will be ascending.

The bad news in 2021 is that the full moon ending 2020 on Dec. 29 (into early morning Dec. 30) is only in its waning gibbous phase. That means the bright, nearly full orb of 81 % illumination, still high in the sky, can outshine the meteor lights.

If you miss the Quadrantids, mark the calendar for the Lyrids meteor shower that peaks April 21-22.

BTW – next three full moons are the Wolf Moon/Old Moon, Moon After Yule on Jan. 28; the Snow Moon/Hunger Moon on Feb. 27 and the Crow Moon/ Lenten Moon/Worm Moon on March 28.

Long Night Moon

If you live in the Northern Hemisphere and thought you didn’t need street lights to meander outside last night, you will have the same brightness tonight  – unless you are in or around Chicago’s expected first big snowfall.

The bright light is thanks to the Long Night Moon, a full moon also called the Cold Moon, it shines from dusk to dawn.

Considered by some as the last full moon of the decade, it will be at its fullest at 9:28 CT Dec. 29, 2020. But because it is still lighting the sky after midnight it might be on some calendars as Dec. 30.

Other sky watchers consider Dec. 12, 2019 the last full moon of the decade.

Full moon for harvest or scary night

October 2020 begins and ends with special full moons.

The month begins with a full moon Oct. 1-2. In the Northern Hemisphere it is known as the Harvest Moon because it is the closest full moon to the fall equinox which in 2020 was Sept. 22.

That makes it special because even though moonrise is later each day by 50 minutes the full moon near the fall equinox takes less time to rise so there is more moonlight. For farmers that means more light to harvest crops.

Because the seasons are just the opposite in the Southern Hemisphere, the Harvest Moon comes in March or April.

But unlike most months, October 2020 has another full moon. That phrase once in a blue moon means that rare occasion when the moon phases complete twice in the same month.

Because October began with a full moon, the phases complete their cycle with a full moon on Oct. 31, 2020. Right. Halloween. Spooky!

Lunar eclipse happenings

Look up the night of Jan 20 into morning of Jan 21. You won’t need a telescope or special glasses. It’s a “Supermoon,” “Wolfmoon,” “Bloodmoon. Ooh, it’s disappearing.

 

Eclipse Times

About midnight, CT, the full moon will have fully moved in its orbit between the earth and the sun. so it won’t be reflecting the sun’s rays. The total eclipse will last a long time – an hour.

The Adler Planetarium site lists Central Times for when it begins and happens as partial eclipse starting at 9:34 pm, and total eclipse from 10:41 to 11:43 pm, Jan. 20. Then watch as the moon emerges from behind the earth Jan.l 21.

In Universal Time the eclipse will last almost 3½ hours from the beginning of the partial phase at 3:34 UT until it ends at 6:51 UT. Totality lasts 63 minutes, from 4:41 to 5:44 UT.

 

Moon Names

So why “Supermoon?” “The moon’s orbit is not a perfect circle,” said Adler Director of Public Observing Michelle Nichols. “Sometimes it is closer to earth so it looks larger,” Nichols said. She noted that the closest it will come near the eclipse will be during the day of Jan. 21 at 1:59 p.m. She calls the appearance of the rising moon seeming to loom large, “an optical illusion.”

She suggested viewers use the thumb test. “Put an arm straight out and cover the moon with your thumb. Then, do it again later when the moon is over head. It will be the same size.”

“Bloodmoon” is a term describing the moon’s color during total eclipse. “Sometimes it looks brick red, sometimes grayish. The sunlight is reflecting at the edge of the earth. The earth has blotted out the blue of the sun so sometimes it could be reddish sometimes grayish. It also depends on how dusty the earth’s atmosphere is,” Nichols said.

“Wolfmoon” is a term for the first full moon of the year, acquired over the years similar to Harvest Moon and Hunter Moon. It also has other names such as Ice Moon according to Time and Date

which explains that people often named the full moons according to the seasons and the phenomena they associated with its time of year.

 

Where to Watch

View outside your abode. See it happening inside on a live stream at Time and Date Live which will be streaming the event on its site.

But to appreciate and enjoy the lunar eclipse with astronomers go over to the Adler for “Lunapalooza.”  The outside observing part is free. Inside events, adults $12, children $8 (members free) include seeing the new Adler show “Imagine the Moon” which charts how people considered the moon over the centuries. Lunar eclipse
