IN August we will see the first of four supermoons visible in 2024. This is also the month when we see the Perseid meteor shower, or the Tears of St Lawrence.

When the Moon rises on August 19, it will be closer to the Earth than normal, and consequently will appear to be seven per cent larger than usual; a spectacular sight. If the weather is cloudy you will have three other chances to see a supermoon this year, in September, October and November.

The August supermoon will be 224,917 miles (361,969km) from the Earth. The October supermoon will be the closest full moon of the year.

The truly dark skies return during August, which can be a spectacular month. If you are looking for the Plough you will find it to the north west of the overhead point, with Cassiopeia at about the same height in the north east.

Vega, one of the summer triangle stars, is now practically overhead and the other two stars, Deneb and Altair, are also very prominent. When looking at Deneb you will see the Milky Way behind it; a wonderful summer sight as it appears almost overhead at this time of the year.

If you continue to follow the path of the Milky Way down towards the southern horizon you will reach the constellation of Sagittarius the Archer. Sagittarius is not seen well from Britain because it is so low in the sky, but if you look towards it you will also be looking towards the centre of our galaxy. The rest of the southern area of the sky is difficult to navigate because it is taken up by formless and faint constellations including Hercules, Ophiuchus and Serpens. The only bright star in this area is the red star Antares in Scorpius, which is still just visible and can be found low in the south west.

If you are up and around early on August mornings, you will be able to see the first signs of the autumn sky, with the Square of Pegasus just appearing above the horizon. Pegasus will become one of our ‘anchor ‘groups in the autumn.

The Planets in August: So far this summer we have been short of planets in the evening sky, and I am afraid this continues through August. The morning is more fruitful - just after midnight the planet Saturn appears, and Jupiter and Mars can be seen just before sunrise in the south east. Mercury and Venus are still too close to the Sun to be seen.

Meteor showers: The most anticipated meteor shower of the year, the Perseids, will peak on the night on August 12/13 when around 80 meteors per hour might be seen. At the present time only the Geminids in December and the Quadrantids in January produce more meteors. Some meteors will be seen a few days before this date and a day or so after.

Many people know meteors as 'shooting stars', but they have nothing at all to do with stars. They are tiny grains of dust that burn up when they enter Earth’s atmosphere. They travel at speeds ranging from 20 to 50 miles per second and we see the result of their destruction in the form of a brief streak of light across the sky.

Although a few sporadic meteors can be seen on any night of the year, there are periods when many can be seen, and these are referred to as meteor showers. These meteors are connected with comets. Comets are essentially very large, dirty snowballs travelling around the Sun. Comets leave a trail of dust behind them and if Earth happens to pass through one of these dust trails we see a meteor shower. There are several major meteor showers during the course of the year.

The Perseids are connected with comet Swift-Tuttle, which was discovered by the American astronomers Lewis Swift and Horrace Tuttle in 1862. This comet takes 133 years to obit the Sun. The Perseid meteor shower has a very long history. The meteors are called Perseids because if you track their paths across the sky they all appear to come from the constellation of Perseus. It should be possible to see the Perseids after about 11pm, at first from the north east, but as the night goes on, all over the sky. An old name for the Perseid meteors shower is 'the Tears of St. Lawrence'. In 258 in Rome a Christian named Laurentius, sometimes referred to as Lawrence, offered the Roman Emperor Valerian 'all the wealth of the empire'. Valerian believed that he meant gold and treasure, but Laurentius meant the people of the empire. Valerian was very annoyed when he did not get the treasure he was expecting and had Laurentius murdered barbarically, by being roasted alive.

The execution was on August 9, and when, the following evening, the Perseids came through on schedule, people thought these meteors were tears from heaven, hence the name ‘the Tears of St. Lawrence’.

The story then goes forward to August 1535 when the French explorer Jacques Cartier was exploring the part of the ‘new world’ that today we call Canada. While camped beside a large river he saw the Perseid meteor shower. Knowing the story of St. Lawrence and being the first European there, he named it the St. Lawrence River. Thus this great river in Canada owes its name to a French explorer and a meteor shower.

Phases of the Moon for August: New Moon 5, First Quarter 12, Full Moon 19, Last Quarter, 26 This month’s full moon is called the ‘Sturgeon Moon’. This is the month when, in past centuries, sturgeon would have been caught in the rivers of Britain. They were considered to be royal fish and the first caught had to be given to either the King or the King’s representative.
