The full moon will begin at 10:36 a.m., Sunday, in CT.
The best time to catch the full supermoon is just after sunset, when an optical illusion known as the moon illusion makes it appear much larger and brighter than when it is higher in the sky.
Supermoon Sunday is at hand, and although some may scoff, the supermoon concept provides a good excuse to take a close look at a celestial sight we often take for granted.
A supermoon is a Moon that is full when it is also at or near its closest point in its orbit around Earth.
The difference is noticeable for close observers - particularly if the moon is near the horizon, where it can be compared with terrestrial landmarks.
A supermoon can appear up to 30 percent brighter and 14 percent bigger than when the moon is at its farthest distance from Earth. The next time the moon will come that close to the Earth will be on November 25, 2034.
Rare sighting of the first and last supermoon of the year will be observed today all over the world including Pakistan.
It's worth noting that a supermoon technically occurs during a new moon, too, but that phenomenon usually isn't referred to as a supermoon since new moons are not visible in the night sky.
The bigger question is whether we'll be able to see the supermoon in Seattle. One is offered by the Virtual Telescope Project based in Rome.
If you miss the first viewing, another good time to sneak a peek is when the supermoon reaches its peak at 4 a.m. on December 4. Not to worry - Nasa has said there are two more in January and February 2018, so clear your schedule. That'll be a super moon, even by Neil deGrasse Tyson's standards.
