Tonight the United Kingdom will be treated to the biggest and brightest full moon of 2019.
"When a full moon appears at perigee [its closest point to Earth] it is slightly brighter and larger than a regular full moon-and that's where we get a "supermoon"," NASA said on its website, noting that the phrase was coined in 1979.
Each month's full moon goes by a nickname; some full moons have several alternate names.
If the sky is clear, the best time to view the phenomenon would be at moonrise at around 7.30pm, a Science Centre Singapore spokesman said.
"The Moon will look extremely large when it rises and sets", NASA astronomer Mitzi Adams wrote in a blog for NASA on Friday. Technically speaking, the moon will hit its peak at 10:54 a.m. ET Tuesday morning, but it won't be visible at that time because it will be daylight.
The handsome moon will reach its closest point to the earth at 9.06am in the United Kingdom, and will be at its fullest at 3.53pm.
It's when the full moon is closest to the earth, and according to EarthSky, this February full moon reaches its exact full phase closer to the time of perigee than any other full moon this year.
Have you seen the Supermoon yet? Another supermoon will take place on March 21, as well, that event having the name "Worm Moon". The moon's diameter will appear to be about 14 percent greater than an average full moon, while its brightness is expected to be near 30 percent more than usual. Also, this month's perigee is the closest of this year's 13 perigees.
What is a Super Snow Moon or Super Hunger Moon? So, brace yourselves for this stunning spectacle, because every full moon after this would just be further away from our planet. It's called a "Super Snow Moon".
Get ready for the biggest supermoon of the year.
If that happens, there's still the third and final supermoon of 2019, which comes in exactly four weeks on March 19.
