If you missed Sunday’s Full Moon feast, it was the opening of a trilogy of supermoons! The next supermoon will appear on the astronomical stage on January 1 and 31, 2018, NASA stated. The supermoon is a Full Moon when it is at its nearest point to the Earth on its orbit. Since the Moon’s orbital path is oval, one side is about 50,000 km farther from the Earth than the other.
The nearby perigee Full Moons seem about 14 % bigger and 30 % brighter than Full Moons that happen near the apogee in the Moon’s orbit. Noah Petro, a research scientist from NASA’s Goddard Space Flight Centre, said that the supermoons are a great chance for people to start looking at the Moon, not just that once but every opportunity they have! December’s Full Moon is recognized as the “cold moon”.
The first-ever glimpse of the Supermoon Trilogy is here, sparking up skies across the US. And, it’s all sorts of wow and sensational! So, go hook your eyes up to the sky now!
Stargazers, astronomers and curious sky-watchers are getting a chance to observe the first and solely supermoon of the year.
On Sunday night, the moon glows 16% brighter and seems 7% larger than its usual size. Last year, an extraordinary supermoon was recorded in the historical records. In November 2016, the moon was nearest to the Earth than it had been since 1948, producing a supersized supermoon. This supermoon will be the head in the sequence of three sequential full moon supermoons; the next two will be in January.
Most scientists suggest watching the supermoon right after dusk and into moonrise, and minutes before the next dawn as well. The best time to experience a full moon supermoon is after moonrise when it is just above the skyline. At this point, a supermoon resembles bigger and vivid than when it’s higher up in the sky. While the moon correctly reached its fullest Sunday morning, it will remain to seem “super” until it sets once again. And for anyone incapable of stepping outside and seeing the moon, you can watch a live stream of the event.
Michelle Nichols, administrator of public observing at Chicago’s Adler Planetarium, described the moon’s captivating close arrival to the Earth. He stated that the moon’s orbit is not a complete circle. It’s more like an oval, so at times it’s closer to the Earth than it is at other times. The variation in distance between these near and far points can be as much as about 30,000 miles.
The distance between the moon and Earth continually changes. Each time the moon orbits the Earth, every 29.5 days, it will reach a close point to the Earth, and a far point, and occasionally, the adjacent location will be close to the date of the full moon, a supermoon.
Nichols says that “For this year’s final supermoon, the perigee distance will be almost 222,135 miles in the early morn hours of December 4.” And while it may appear super, the term “supermoon” is not the official term for the astronomical phenomenon. The relevant term is “perigee-syzygy.” Perigee-syzygy has happened three previous times in 2017.
Though, December’s full moon is the only apparent supermoon. That’s because the earlier two were around the time of a new moon, which isn’t noticeable in the sky. For Muslims all over the globe, this supermoon pronounced a critical date. According to the Islamic calendar, the months start with the glimpse of the waxing crescent moon right after sunset. This month’s full moon progresses the middle of Rabi’ al-awwal, the third month of the calendar. This is a time when maximum Muslims throughout the world celebrate Mawlid or the birth of the prophet Muhammad. While different sects of Islam commemorate the prophet’s birthday on various days, the majority of Muslims celebrated his birth which coincidentally joined with this year’s only full moon supermoon. While the moon undoubtedly appears both bigger and brighter than usual, our eyes tend to trick us into seeing the moon as more significant than it indeed is.
Nichols states “When you look at it from near the horizon, there’s an optical illusion.” When the supermoon is observed low on the extent, it appears vast. This is identified as the moon illusion, and the moon hasn’t risen; it’s a trick your eyes are playing on you. Nichols says that despite the noticeable difference between a regular full moon and a supermoon, it is not as big as it appears. Estimating that a full moon can be covered with a fingernail, even a 7% larger moon may not look that much more prominent.
For everyone waiting to catch a sight of the last supermoon of 2017, taking images to preserve the moment can be comfortable. Bill Ingalls, a NASA photographer, tells that those catching the event by their phones have to focus on the proper light balance. “Tap the screen and retain your finger on the moon to lock the focus. Then slide your finger up or down to darken or lighten the exposure.”
For those using DSLR cameras, Ingalls recommends utilizing another subject in the image, like a person, pet or landmark to relate to the size of the moon. “Usually I find when the moon is near the skyline I have a better chance of combining it with a landmark or person, but there are no restrictions, and sometimes a tall object can be utilized when the moon is at a very high edge.”
While the supermoon can come out looking larger in photos than it does when gazing at it in person, Nichols asserts it is an unlikely chance to get people excited about science and astronomy. The supermoon receives headlines because the moon’s a little bigger and a little brighter, but people get frustrated that they can’t eternally tell the difference. Still, it’s a great reason just to go out and look at the sky.
