SUPERMOON JULY 2022

by David Moore, Ireland’s best known astronomer! (and editor of our magazine)

A SuperMoon will be seen over Ireland on Wednesday July 13th and we want your reports and photos (see below). We wrote about it in our July magazine which you should join Astronomy Ireland to get each month:

But here are some brief details so you can email us a report of what you see and your best photo if you have a camera phone.

On Wednesday the Full Moon will rise at 10:30pm. This is a SuperMoon, see explanation below .

It might take an hour for it to clear buildings or trees on your southeast horizon but you can see the Moon all night until sunrise at 5am, so if there are any clouds around, just keep checking for breaks and you will see it. The Moon ‘looks’ Full to the naked eye the night before AND after Wednesday so you can effectively see this SuperMoon Tuesday, Wednesday, and Thursday. From Ireland, the Moon rises on Tuesday at 9:30pm, Wednesday at 10:30pm, and Thursday at 11:10pm.

MOON ILLUSION

There is an optical illusion associated with the Moon rising where it ‘looks’ much larger (2 or 3 times larger some times!) than it actually is. I’ve seen this happen many times. No one is sure why the human eye/brain combination makes the Moon look bigger but it is a powerful and convincing effect.  The SuperMoon is slightly bigger than a normal Full Moon AND add the Moon illusion and it should be very spectacular as it rises.

When the Moon is higher in the sky you won’t see the Moon Illusion effect but it is still the brightest Full Moon you will ever see.

SUPERMOON EXPLAINED

The Moon goes around the Earth is a slightly elliptical (egg-shaped) orbit. At some times it is 15% closer than when at its farthest from us. This causes the Moon to be 30% brighter in the sky compared to when it is at its most distant.

When the Full Moon occurs at the same time that the Moon is at its closest point we get a SuperMoon. This usually happens 3 or 4 times a year. This (July 2022) SuperMoon is the 3rd of 4 Supermoons in 2022, with the next, and final one of 2022, occurring on the night of August 11.
