The Only Supermoon of 2017 Is Happening. Here's When to View It

There will be one on New Year's Day followed by another on January 31, which, according to NASA, will be a "super blue blood moon".

While scientists argue about the influence of the close passing of Earth's natural satellite for geophysical processes, the Moon is inexorably approaching and promises to be an interesting phenomenon for all the earthlings who are lucky enough to see this spectacle.

Each month the moon rotates around the earth in an ellipse rather than a flawless circle. NASA officials said the second supermoon is coming on New Year's Day. When this happened a year ago, the moon appeared up to 14 percent larger and 30 percent brighter than normal.

The moon will reach perigee at 3:45 a.m. ET on Monday when it is 222,135 miles from Earth.

This year's will occur Sunday, Dec. 3. Time your viewing for just after local sunset, National Geographic suggests, when the "moon illusion" will make the orb look especially large and vibrant.


The bigger question is whether we'll be able to see the supermoon in Seattle.

The next supermoons are on January 2 and January 31, 2018. This makes the full moon appear even larger and luminous due to its increased proximity to the planet.

An image of the moon taken by NASA's Lunar Reconnaissance Orbiter is shown in two halves to illustrate the difference between the apparent size of a supermoon (left) and a "micromoon" (right).

If you're clouded out on Sunday, you can still get into the supermoon spirit on Sunday with streaming video from the Virtual Telescope Project or the Slooh online observatory.

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.
