Throughout 2021 we are set to receive four Supermoons in a row.
The Moon’s orbit around Earth is slightly oval shaped or elliptical. So, every month there’s a time when the Moon is at its closest distance to Earth (at perigee) and another time when it is at its furthest distance from Earth (at apogee).
“Supermoon” is not an official astronomical term. Astronomers often say “Moon at perigee” or “Moon at apogee” in conversation. When perigee coincides with the full Moon, it’s popularly called a “Supermoon”. And when the full Moon coincides with apogee? Well, it’s a “Micromoon” or a “Minimoon”! Although these are not official astronomical terms, they certainly grab your attention which means we have more people heading outside to gaze up at the wonderful night sky.
When to look: Here are the four dates and rising times for the 2021 Supermoons:
- 6:55pm on 29th March
- 6:01pm on 27th April
- 5:17pm on 26th May
- 5:50pm on 25th June.
Which direction to look: The Moon rises in the east.
Where’s the Best Place to see the Supermoon Rise?
Find a place where you can see the eastern horizon well. Anywhere will be OK as long as you have a pretty clear view to the eastern horizon without buildings or trees blocking your view.
If you’d like to try and photograph the Supermoon, think about what type of landscape you’d like to capture in the foreground of your image. A group of trees, an interesting building or a body of water like a lake or river. Remember, this landscape needs to be in your view as you look east.
Does a “Supermoon” appear larger to the naked eye?
Do you think you will notice a difference between a “Supermoon” and a usual full Moon? The difference in the apparent size between a usual full Moon and a “Supermoon” is barely noticeable to the naked eye. So you won’t notice a difference in size. For some comparisons between “Supermoons” and “Micromoons”, check out the NASA website. Plus, Ian Musgrave, Australia’s Astroblogger made this comparison.
What craters can you see on the Moon?
When you observe the Moon, take it one step further and identify a crater or two! There are some great tools that help you out with maps of all the features on the surface of the Moon. Before you know it, you’ll be pointing out the Tycho Crater or the Sea of Tranquillity to friends and family! Try some of these free apps and software:
