When is the full moon in July? The Buck Full Supermoon 2023 Time & Date

Last Updated: November 9, 2023

The upcoming full Moon in July will grace our night sky on Monday, July 3, at 7:39 A.M. EDT / 11:39 A.M GMT. During this particular phase of its lunar cycle, the Moon will have aged 14.62 days, offering a perfect illumination of 100%.

With a tilt angle of 97.93°, our natural satellite will be located approximately 363,776.22 km away from Earth. This equates to about 226,040.06 miles, or roughly 0.00243 Astronomical Units (AU). This means the Moon will only be about 0.3% away from its average perigee distance (closest distance from Earth), so it will earn the title of supermoon!

In terms of light travel time, this distance corresponds to approximately 0.02022 light minutes. In the realm of astrology, the Moon will align with the sign of Capricorn on this day. This full Moon is the first one of the summer season which started on the previous month during the summer solstice!

Moon gazing information for the July Full Supermoon 2023

The Moon’s magnitude, a measure of its brightness, will be -12.78. In astronomical terms, a lower value signifies a brighter object, which means the Moon will be exceptionally bright during this event.

The terms Ra/Dec refer to the Moon’s position in the sky, known as Right Ascension (Ra) and Declination (Dec). These coordinates will be 18h49m30s and 27°41’S, respectively, corresponding to the celestial longitude and latitude.

Similarly, the terms Az/Alt denote the Moon’s azimuth and altitude, which represent the Moon’s direction and height from the horizon, respectively. These will be 213°34’03.8″ for the azimuth and +16°30’49.2″ for the altitude.

The Moon will have an apparent diameter of 32.59 arcminutes, in the higher end, so even though it will be quite enjoyable to the naked eye, observing it with a basic set of binoculars or a small telescope, will allow for a detailed exploration of its surface features.

Additional information:

  • Moonlight intensity: High
  • Moonlight shadows: Strong
  • Culmination time: location dependent
  • Moonrise time: location dependant
  • Moonset time: location dependent
  • Supermoon? Yes
  • Micromoon? No
  • Blue moon? No

Nearby night sky objects

The Moon will be located in the heart of the Sagittarius constellation.

Why is the July full Moon called the Buck Moon?

The seventh full Moon of the year is the Buck Moon. Deers were a significant part of the Native American tribes’ lives as they were a valuable resource, providing food, clothing, shelter, tools, and more.

Male deer shed their antlers every year., and during this time of year, the new antlers of bucks would push out from their foreheads, coated in velvety fur. Therefore, the Moon was dubbed the Buck Moon.

Other tribes called it the Thunder Moon in reference to the time of year when thunderstorms are most frequent, the Salmon Moon, and the Raspberry Moon. Celtic names included the Calming Moon, Wyrt Moon, Herb Moon, and Mead Moon.

To the Anglo-Saxons, it was known as the Hay Moon for the July hay harvest. In China, it is known as the Hungry Ghost Moon.

Observing this buck full Moon with astronomical equipment

The Moon offers a variety of interesting features that you can observe, even with modest equipment. The Moon is without a doubt the easiest celestial object to observe with a backyard telescope or a pair of astronomical binoculars.

The Moon can shine a rather bright light when it is full so the use of a special lunar filter can help improve your view of the Moon. This is an additional component that reduces the amount of light coming into the telescope, making it easier to see the details without being blinded. 

It essentially works much like ‘sunglasses’ for your telescope. It reduces glare and improves contrast, allowing you to see more detail. The filter threads into the bottom of an eyepiece, so it’s easy to add or remove as needed.

  • A smaller aperture telescope (60mm to 80mm) can provide good views of the moon. You’ll be able to see a decent amount of detail, including larger craters and lunar maria.
  • Medium aperture telescopes (around 100mm to 150mm) will give you a much better view, revealing many more features and allowing you to see smaller craters and other details.
  • With large aperture telescopes (200mm and above), that’s where the magic happens! You’ll see more detailed views of the edges of lunar maria, where they meet the highlands. You’ll be able to discern more subtle color differences in the lunar surface as well as mountain ranges casting subtle shadows on the lunar surface. You might be able to see hints of the lunar domes, which are gentle, rounded mounds thought to be the remnants of ancient lunar volcanoes.

Be sure to choose the correct eyepiece for an appropriate magnification power as it will greatly influence your field of view at the eyepiece. Try my field-of-view calculator to determine the best eyepiece for your lunar observations.

Planning your lunar observation with Stellarium

Stellarium is a free open-source planetarium for your computer that shows a realistic sky in 3D, just like what you see with the naked eye, binoculars, or a telescope. It’s one of my favourite stargazing applications, I use it on a weekly basis and it’s super easy to use.

Here is a step-by-step guide to using it for timing your observation of the upcoming Buck full Moon: 

  1. Set Your Location: Open into your internet browser. In order to find the accurate rise and set times for the Moon, you need to set your geographic location. Click on the “Location Window” button on the left toolbar. In the window that pops up, search for your city in the “Search” field, then click on your city’s name in the list. This sets your location.
  2. Set the right time: Stellarium can show you the sky at any time, past, present, or future. To get the full moon time, which in July will be on the 3rd, you need to click on the “Date/time window” button on the bottom right of the screen. You can also manually adjust the time by hours and minutes and see the sky moves before your eyes.
  3. Locate the Moon: Now, you need to find the moon in the sky. You can do this by using the search function. Click on the “Search Window” button on the centre top of the screen. Type “Moon” into the search field and press enter. The view should now center on the Moon.
  4. Check Moonrise and Moonset Times: Once the Moon is centered, an information box should pop up on the upper left corner of the screen. This box will provide various details, including the moonrise and moonset times for the chosen day.

Lunar Luminosity: the full Moon's light influence on the world

The full Moon has a few notable influences on Earth:

  • Tides: The gravitational pull of the moon causes the Earth’s oceans to bulge out in the direction of the Moon. 
  • Light: A full Moon provides significant natural light at night, which can affect nocturnal animals’ behavior and plant life.
  • Floral behaviours: Some species of plants, such as the Ephedra foeminea (also known as the werewolf plant) release their pollen in sync with the full Moon.
  • Human behavior: There have been many theories on how the full Moon may affect humans in different, whether it be our sleep pattern, our cardiovascular system, menstruation cycles, and our mood and mental health. However, despite many scientific studies that have been conducted in the last ten years,  scientists have not been able to prove the effects of the full moon on human psychology or behavior.

Full Moon celebrations around the world

The full Moon has been a significant cultural symbol and theme throughout human history, appearing in myths, legends, superstitions, and rituals across the globe. In Thailand, the full Moon is celebrated every month during the infamous full Moon party. 

In Sri Lanka, each full Moon day is a public holiday, known as Poya. Each Poya has its own name and is associated with Buddhist events. On these days, people often go to the temple for religious observances.

In Wiccan traditions, an Esbat is a ritual observance of the full Moon. It’s a time for meditation, divination, and spellwork that align with the peak of the Moon’s energy.

In China, the Mid-Autumn Festival also known as the Moon Festival, is celebrated during the full moon of the 8th lunar month (usually September). Families gather to admire the Moon, eat mooncakes, and in some regions, light lanterns.

If you know of any more celebrations that should be added to this list, let me know in the comment. In the meantime, be sure to take some time to look up and enjoy this upcoming full Moon.
