IN full moon July, also called the “Bucks Moon” or “Thunder Moon”, will occur on July 23 at 10:36 pm ET (0236 GMT on July 24); the nearly full moon will close pass of Saturn on July 24 and Jupiter on July 25.
According to observers in New York, on July 23 at about 4:46 am local time, observers will see an almost full moon. timeanddate.comand he will rise that day at 20:32.
A full moon occurs when the moon is on the opposite side of the earth from the sun. Earth observers see that the Moon reflects sunlight, unless the Moon’s orbit carries it exactly within the Earth’s shadow – moon eclipse…
The time of the full moon depends on the time zone, since the full moon is calculated using the position of the moon relative to the center of the earth, not a given point on the surface.
Orion GoScope II 70 telescope kit for the moon: $ 89.99 at Amazon
If you know a boy who cannot get enough of the moon, then he will be in awe of the views through the Orion GoScope II. This small telescope, which can detect craters and seas at close range, comes with a carrying bag and a map of the moon.
However, the height of the moon in the sky depends on latitude. The orbit of the Moon and the Sun follows a trajectory called the ecliptic, which is the plane of the Earth’s orbit projected onto the sky. The Moon’s orbit is slightly tilted about 5 degrees to the ecliptic. That is why we do not have lunar eclipses every full moon and solar eclipse every new moon.
However, this also means that the full moon will be lower in the southern sky during the summer in the Northern Hemisphere. The opposite is true in the Southern Hemisphere for the full moon in June, July and August (their winter), which will be higher in the northern sky. The situation reverses in winter in the Northern Hemisphere.
The full moon is so bright that filters may be required through binoculars or a small telescope for highlights. There is no danger to the eyes, but the details are more difficult to discern, because there are few visible shadows in the central part of the lunar disk – if there were an astronaut there, the sun would be directly overhead. Lunar filters are available that can highlight some features, or you can simply observe the moon a few days before or a few days after the full phase, when shadows make it easier to identify surface details.
On July 24 at 12:38 pm ET (1638 GMT), the last full moon will be conjunct Saturn. In-The-Sky.orgpassing just under 4 degrees (about 8 lunar diameters) south of the planet.
The moon will still be below the horizon, so the closest moment will not be visible from the continental United States, but in New York, Saturn rises at 20:43 local time and the moon at 21:16. 22:00, Saturn will be higher and to the right of the Moon, and Jupiter – to the left of them; these three will form an oblate triangle, and Saturn will be about 12 degrees above the southeastern horizon.
The moment of connection will only be visible from Eastern Europe, Africa or Asia; for example, in Tokyo, conjunction will occur at 1:38 am local time on July 25, about an hour after the Moon and Saturn reach their highest point in the sky (about 35 degrees above the southern horizon). The Australians will have a connection a little later – on July 25 at 2:38 am local time; Saturn will be at 58 degrees in the northwest sky.
A day later, the Moon passes Jupiter. Seen from New York, the moon will travel just over 4 degrees south of Jupiter at 9:21 pm local time, but the moon won’t rise until 9:52 pm, so observers on the East Coast will just miss the conjunction again. myself. Jupiter will first rise at 21:34, and by about 22:30 it will be about 10 degrees above the horizon, and the Moon will appear about halfway between the horizon and the planet. Both bodies will be visible throughout the night; By 2:55 am on July 26, the temperature rose to 36 degrees.
Here again it will be easier to see the connection as you go east; in London, conjunction occurs at 2:21 a.m. on July 26, so by this time the Moon and Jupiter will be well above the horizon – about 20 degrees – in the south-southwest.
Other planets will be less impressive on a full moon.

On July 23, the sun sets at 20:19 local time in New York, and the planet Venus sets about an hour and a half later at 21:49. heavens-above.com The evening star is calculated to be visible just after sunset, although it is a little difficult to spot as the sky will be a little light.
Mercury, meanwhile, will be the morning star rising at 4:53 am local time in New York City, just under an hour before sunrise. Here, too, it will be difficult to locate the planet, as the sky will glow. Be careful when observing planets near the Sun, as viewing through binoculars and accidentally focusing on the Sun is a sure way to permanently ruin your vision. By sunrise, the height of Mercury in the northeast will be only 8.6 degrees. But with a flat horizon (for example, over the ocean) and a very clear sky, you can still catch it.
Mars will be in the west at 9:32 pm local time in New York. Because it sets so soon after sunset, it, like Venus, will be very difficult, if not impossible, to see against the still-lit sky.
Constellations on display
During the July full moon, the northern hemisphere summer constellations will be visible throughout the night, but the brightness of the moon will eclipse the dimmest stars. The Summer Triangle – Deneb, Altair and Vega – will approach its zenith in the eastern sky closer to midnight, and Antares, the brightest star in Scorpio, will also reach its highest point in the sky.
Looking to the roughly northwest at about 10:30 pm local time, the sky will be completely dark, and one of the first stars to be seen in this area is Arcturus, the brightest star in the shepherd Botes. If you turn a little to the right (north), you can see the Big Dipper, the “bowl” of which will be turned up. The two stars on the right side of the bowl will point to the North Star. In the other direction, you can draw an arc along the handle and “arc to Arcturus”, and then continue along Spica, the brightest star in Virgo, located low in the southwest.
Turning left (south) reveals Antares, the “heart” of Scorpio, the legendary creature that killed the hunter Orion (appearing in winter). Directly above Scorpio can be seen a tall, roughly rectangular shape formed by several fainter stars; it is Ophiuchus, the healer who raised Orion from the dead after Scorpio killed him. Ophiuchus is harder to see from urban areas as the stars are fainter than Antares.
But if you turn left and up, you get to Altair, the brightest star of the Aquila Eagle and the southernmost of the three stars of the Summer Triangle. If you look north (up) from Altair, then you get to Deneb and Vega – Vega will be closer to Zenith.
How Buck Moon got its name
Connected: Full moon names (and not only) for 2021
Native American peoples have various names for the July full moon; the names reflect that it is summer in the Northern Hemisphere. “Traditionally, the full moon in July is called the Deer Moon because the antlers are in full growth at that time,” says the old farmer’s Almanac. “This full moon was also known as Thunder Moon because there are so many thunderstorms this month.”
The name “Thunder Moon” was borrowed from the indigenous people living in the eastern United States, where summer is the season of thunderstorms. However, the July full moon had other names as well. According to the Ontario Native Literacy Coalition, the Ojibwe called it the crimson moon and the Cree called it the “molting moon,” as some birds begin to molt in the summer.
New Zealand’s Maori used a lunar calendar called the Maramataka, which measured the months between successive new moons. The lunar month from June to July (which this year includes new moons from June 10 to July 9) is called Hōngongoi, or “man is now very cold and kindles fires before which he warms himself.” according to the Encyclopedia of New Zealand. This lunar month was the second month of the year for the Maori.
The Chinese lunar calendar notes that the July full moon falls on the sixth month, Héyuè, or lotus month, when the flowers of the same name are in full bloom.
Muslims celebrate Eid al-Adha, starting on July 20, as part of a festival that lasts about four days and ends on a full moon day. Eid al-Adha honors Abraham’s willingness to sacrifice his son to God, as indicated in the Bible and the Qur’an.
For the Jewish people, the middle of the moon (full moon) falls on the month of Av and is a holiday Tu Bi Av which is a “holiday of love” and auspicious time for weddings.
