SUPER MOON. This Wednesday, July 13, 2022, lift your eyes to the sky to witness the “Super Thunder Moon.” When to watch? How far from earth? What effects? Know everything.
[Mis à jour le 13 juillet 2022 à 20h20] Note to moonlight lovers: the supermoon this Wednesday evening, July 13th, the eve of the national holiday, will be spectacular! Once again, the full moon will be closest to our blue planet, and we’ll be able to see it larger and brighter than usual, a phenomenon nicknamed the “supermoon” but scientists prefer to refer to as “perigee syzygy.” point in its orbit that is closest to Earth.
While you wait for the photos, where the weather is just as kind to its observation as the previous supermoon, here are the most beautiful photos of the June 14 supermoon, taken in France, the United States, China or even Russia:
For those who miss the astronomical event, a third and final supermoon will be visible on August 10 of this year, 2022. Another astronomical phenomenon, Comet C/2017 K2, will make its closest approach to Earth tomorrow, July 14, but will only be visible with a telescope. Discover below all the information about the supermoon’s distance from our Earth, its observation in mainland France or elsewhere and its scientifically proven effects.
The July 13 supermoon will reach its perigee at exactly 11:50 a.m., according to the Institute of Celestial Mechanics and Ephemeris Calculation (IMCCE). Its observation in France is only possible from moonrise at 22:23 at night until 04:52 on July 14, the national holiday.
The phenomenon, dubbed the “Super Moon” by astrologer Richard Nolle, but which scientists prefer to refer to as the “phenomenon of perigee syzygia,” occurs when the point in the lunar orbit is a minimum distance from Earth. When is the moon closest to the earth? At a distance of less than 360,000 km (the average distance between the Earth and the Moon is 384,400 km) according to the Paris Observatory. This Wednesday, July 13, the full moon will be approximately 357,264 kilometers from Earth.according to the Institute of Celestial Mechanics and Ephemeris Calculation (IMCCE).
The Super Thunder Moon bears this name, given by Native American tribes because it coincides with the stormy season due to the high summer heat. In Native American tradition, it is also called Deer Moon because deer antlers also grow back at this time of year.
The Supermoon phenomenon will only be visible from countries where it is dark when it passes behind Earth, which will be the case in France on Wednesday July 13 from moonrise at 10:23 p.m. The super moon can only really be observed with the naked eye with binoculars or telescopes after sunset. To observe a supermoon in optimal conditions, it is necessary to equip yourself with astronomical glasses or a telescope far from air pollution or to go to one of the clubs of the French Astronomy Association (AFA). See the map.
To observe all the details of the next supermoon, you need to arm yourself with a telescope or binoculars and be as far away from the city lights as possible. The super moon can only be observed without a telescope in very good weather. In order to observe a super moon, the sky must not be overcast.
In astronomy, this event is known as “perigee syzygia,” although the supermoon’s name has nothing scientific about it, being a invention of astrologer Richard Nolle in 1979. “A supermoon occurs when the full moon coincides with the moment when the moon comes closest to Earth in its elliptical orbit, a point called perigee,” explains the NASA website.
By supermoon we understand a celestial phenomenon that can be traced back to two elements: The only satellite of planet Earth comes closest to us on a full moon evening.
A Supermoon appears slightly brighter and larger than a Full Moon simply because it appears at perigee, at its closest orbit point less than 360,000 km away.
The Full Moon’s proximity to our planet Earth means its effects on tides, mood and sleep are even more pronounced. As explained in a Swiss scientific study published in the journal Current Biology in 2013, “a lunar rhythm can modulate the human sleep structure”. This means that the time it takes to fall asleep is increased by 5 minutes, deep sleep is reduced by 30% and the duration of sleep is reduced by 20 minutes. As a result, levels of melatonin, a hormone secreted during our sleep that plays a role in mood, are lower, which can lead to irritability or even depression.
While lunar eclipses can occur several times a year, the coincidence of the two phenomena (super moon and total solar eclipse) is rare and results in what is known as a blood moon. A few centuries ago, “blood moons” were considered to herald great catastrophes. Today we know that this color is due to the projection of sunlight. During the lunar eclipse, it is possible to “see the reflections of all sunrises and sunsets on Earth on the lunar surface,” a phenomenon resulting from “a rare alignment of these three astronomical cycles,” as Professor Jason Aufdenberg pointed out at Embry-Riddle Aeronautical University in Florida.
When a supermoon is announced as a blue supermoon, it has nothing to do with its color. It is so named because it is the second full moon of a calendar month. A fact that only happens every 19 years. The last Super Blue Moon was on January 31, 2018. The conjunction of the Super Blue Moon and Super Blood Moon phenomena had not occurred since March 31, 1866, and the next will not occur before January 31, 2037. The use of the term “blue” would result from an error in an article in the American Journal of Amateur Astronomy sky and telescope, in 1946. The article in question was entitled “Once in a Blue Moon” and was written by journalist James Hugh Pruett, who misinterpreted the 1937 Maine Farmers’ Almanac. And so this confusing expression went around the world in no time. .! Every two to three years the year includes 13 instead of 12 full moons. The super blue moon is therefore associated with the number 13. Medieval belief associates these 13 full moon years with natural disasters, but gardeners tend to conjure up particularly rainy years that are not conducive to harvest.
The term “supermoon of the century” should be used with caution. The last time our satellite came this close to Earth was in 1948. On November 14, 2016, the moon was the largest it had been since 1948. NASA, dubbed the “Super Extra Moon,” announced one of the “most impressive Moons” of Apparitions of the Century”. But if you were expecting to see a gigantic moon, you may have been disappointed. “This full moon [était] actually closest to earth for 2016 […]but its change in apparent diameter [n’était] absolutely not easy to see with the naked eye,” explained scientific author Guillaume Cannat on his blog Around the Sky. ” he continued. Although the phenomenon is quite extraordinary, Guillaume Cannat then warned us about the “extraordinary” nature of his observation.
Mark the date of the next Supermoon on your calendar: Wednesday August 10, 2022, scheduled at 7:08 p.m. The next Super Blue Blood Moon will only occur again January 31, 2037.
