The first of three supermoons will take place this weekend, according to Earthsky.org.
A supermoon takes place when the moon is closer to Earth in its normal orbit than average. It is most notable when it occurs at the same time as a full moon.
"It is called a supermoon because this is a very noticeable alignment that, at first glance, would seem to have an effect. The 'super' in supermoon is really just the appearance of being closer," James Garvin, chief scientist at NASA's Goddard Space Flight Centre, according to CBS News.
Those in the UK will get the best view of the supermoon at around midday on July 12, though people on the west coast of the U.S. will be able to view it at around 4 a.m. PDT.
It could be viewable as early as tonight (July 11) and as late as tomorrow night, according to Earthsky.org.
"Technically speaking, the moon turns full at the instant that the moon lies most opposite the sun for the month," according to the report. "Because the moon stays more or less opposite the sun throughout the night, watch for a full-looking moon in the east at dusk, highest in the sky around midnight and low in the west at dawn.
The moon will look full for a few nights around the night of the full moon.
NASA recently confirmed that August's full moon will be the closest supermoon of the year. It will come within 221,764 miles of Earth.
The next supermoons are set to take place on Aug. 10, and September 9.
The 2014 supermoon schedule includes:
-Full moon on July 12 at 7:25 a.m. ET
-Full moon on August 10 at 2:09 p.m. ET
-Full moon on September 9 at 9:38 p.m. ET
Garvin said the supermoon will only have a "minor" effect on Earth.
Besides the change in appearance, ocean tides will also be larger than usual, according to Earthsky.org.
"Will these high tides cause flooding?" it said. "Probably not, unless a strong weather system accompanies the perigean spring tide. Still, keep an eye on the weather, because storms do have a large potential to accentuate perigean spring tides."
