Leaves are beginning to fall, the air is getting cooler and thoughts are turning to Halloween.
Autumn is on its way - and for astronomy fans, autumn also means it's time for the Harvest Moon!
The Harvest Moon is the name given to the full Moon that takes place closest to the autumn equinox.
This means that the Harvest Moon can fall any time between September and October.
It is called a Harvest Moon because the Moon is particularly bright and rises early.
In the past, this allowed farmers to extend their working day and work by the light of the extra-bright Moon, gathering crops to prepare for the winter months - hence 'harvest'.
The best night to view this autumn's Harvest Full Moon will be at 12:54am on 21 September but if, like most of us, you're in bed by then, you can still view it the day before or after.
The Autumn equinox is on 22 September, so the full Moon closest to this date is actually before the equinox this year.
Provided the weather is clear, it should be relatively easy to get a good view of the Harvest Moon.
The great thing is that you don't need a telescope to see it! Although keen stargazers might use one to get a closer look.
When it gets up into the centre of the sky, it will be shining a brilliant white. Let's hope it's a clear night!
The next full Moon to grace our night skies will be the Hunter's Moon - the 10th full Moon of the year.
Like the Harvest Moon, the Hunter's Moon is brighter and shines for longer, traditionally giving hunters more light to catch food.
