The Harvest Moon Rises

We have been fortunate this year in having two supermoons and also a Blue Moon. The first supermoon of 2024 was in August. The second one will rise on 18 September and is the Harvest Moon.

The full moon in August will also be a supermoon and a partial lunar eclipse.
The full moon closest to the September equinox is called the Harvest Moon. It is unique because the Moon rises close to the same time several days in a row.
The full moon appears orange when it is nearer the horizon. This is because we see through the maximum thickness of the earth's atmosphere which absorbs blue light and transmits red light.

Why a Harvest Moon?
The term ‘Harvest Moon’ refers to the full, bright moon that is closest to the Autumnal Equinox or the start of autumn. The name is from the time before electricity, when farmers depended on the moon's light to harvest their crops late into the night.
Most years the September full moon is the Harvest Moon but every three years it is in the month of October. When the Harvest Moon falls in the month of October it means that September’s full moon can use its traditional name of Corn Moon.
Different types of moons
Blue Moon – when a full moon occurs twice in the same month
Harvest Moon – this is around the autumnal equinox when farmers do most of their harvesting
Supermoon – Supermoons are said to appear 14% bigger and 30% brighter than usual.
Blood Moon – occurs during a total lunar eclipse
What is the origin of the moon names?
The names given to the full moons during the year are derived from the North American traditions.
Many of these ancient moon names have been given based on the behaviour of the plants, animals, or weather during that month.
There are a total of 12 full moon phases during the annual lunar cycle plus the occasional Blue Moon and each full moon has a unique name and reflects the landscape around us.
It is said that they were the names given by Native American tribes and included into our modern calendar. However the full moon names we now use also have Anglo-Saxon and Germanic roots.

Why a full moon?
Full moons occur every 29.5 days or so as the moon moves to the side of Earth directly opposite the sun, reflecting the sun's rays off its full face and appearing as a brilliant, perfectly circular disk.
A full moon occurs when the moon's earth-facing side is completely illuminated by the sun. Scientists say that when you see the moon looking really large as it rises in the sky your brain is actually playing a trick on you.
There are many reasons as to why this is, but the main theory is that when the moon is low on the horizon it can be compared to earthly things, like buildings and trees, and this is why it seems huge.
Tips for seeing a full moon
Moons rise in the east and set in the west
If viewing from inside your house it is best to turn off lights so as to view the night sky
If outside it is best to go somewhere high so you can see the moon rise above the horizon
Viewing outside is the best and away from street lights and light pollution

Why a supermoon?
A supermoon is when you look up at the night sky and the full moon looks so close you feel as if you could almost touch it, although sometimes the difference is hard to spot with the naked eye.
This is called a moon illusion as the full moon appears much larger when it rises behind a distant object on the horizon.
When the moon is closest to the earth a supermoon occurs. A supermoon will appear 14% larger and 30% brighter than usual. A supermoon looks especially large when rising and setting.
The moon will be 30,000 miles closer than usual. It sounds a lot, but the average distance between the earth and moon is 238,900 miles, so it’s not that huge a difference.
If you go outside on the night of a full supermoon you should actually notice that it is exceptionally bright.

Sleep and a full moon
The moon affects the tides because of gravity and it is often said that full moons can also influence us. Issues with our immune system can be caused by lack of sleep or disturbed sleep. Some people find falling asleep harder during a full moon along with less time spent in a deep sleep. This lack of sleep can sometimes cause people to have worse headaches often called 'moon migraines'.
Moon facts and folklore
The moon's diameter is 2,160 miles
The sun and moon are not the same size
The moon is a lot smaller than the sun
The moon's surface is dark
The moon has quakes
There is water on the moon
The moon has a very thin atmosphere
A person would weigh less on the moon
The dark side of the moon is a myth
We only see the near side of the moon, the other side is the far side
Earth's moon is the only place beyond earth where humans have set foot. 12 people have been on the moon.
The best time to see the full moon in the UK is in the evening after sunset as that is when the moon is closest to the earth. So let's hope we get some clear sky to be able to see the full moon, but it will be visible for a few days around the peak.
