The next Full Moon is on the 3rd of August. The Moon rises around 22:00 on the evening of the 3rd in the South East. The actual full moon isn't until 16:58 however the Moon will be below the horizon. This Full Moon is also know as The Sturgeon Moon.
If you manage to catch a full moon as it rises above the horizon it will appear to look much bigger. Check out the video further down the page that explains why!

THE NEXT SUPERMOON ISN'T UNTIL 2021 NOW!
The scientific name for a Supermoon is Perigee Full Moon. A Supermoon occurs when the full moon is at the closest point of its orbit to the Earth. The Moon will look much closer and brighter.
The Supermoon is normally best viewed as it rises. The best time to view it is when it is just rising, as it will appear to look much larger.
