Seattle Supermoon: A Celestial Spectacle
The supermoon graces Seattle skies, appearing larger and brighter than usual due to its close proximity to Earth. This stunning lunar event offers a unique opportunity for skywatchers to observe the moon in all its glory. The phenomenon happens when the moon is in its full phase near the closest point to Earth in its orbit.
What is a Supermoon?
A supermoon occurs when a full moon coincides with the moon’s closest approach to Earth in its elliptical orbit, a point called perigee. Because the moon’s orbit isn’t perfectly circular, its distance from Earth varies. When a full moon occurs near perigee, it appears noticeably larger and brighter than an average full moon. According to Wikipedia’s Supermoon article, the term is not strictly defined, leading to some variation in how the term is applied.
Why Does the Supermoon Look Bigger?
The apparent increase in size is an optical illusion, primarily due to the moon being closer to Earth. The difference in distance between perigee and apogee (the moon’s farthest point from Earth) can be significant, leading to a noticeable change in the moon’s perceived size. While the actual difference in size is relatively small, it’s enough to make the supermoon appear more impressive to the naked eye. In addition to proximity, the “moon illusion,” which makes the moon appear larger when it’s near the horizon, can further enhance the supermoon’s perceived size.
Viewing the Supermoon in Seattle
Seattle offers several excellent locations for viewing the supermoon. Parks with open skies and minimal light pollution are ideal. Kerry Park provides panoramic views of the city skyline and Elliott Bay, making it a popular spot. Discovery Park, with its expansive meadows and bluff overlooking Puget Sound, is another great option. Away from the city center, less light pollution in areas like Snoqualmie Point Park give better viewing opportunities.
Tips for Observing the Supermoon
No special equipment is needed to enjoy the supermoon. Find a spot with a clear view of the sky, away from city lights. Give your eyes about 20 minutes to adjust to the darkness for optimal viewing. Binoculars can enhance the view, revealing more detail on the lunar surface. Check the weather forecast beforehand to ensure clear skies.
Frequently Asked Questions
When is the next supermoon visible in Seattle?
Check astronomical calendars and websites for specific dates of upcoming supermoons. Space.com and timeanddate.com are reliable sources.
Does a supermoon affect tides?
Yes, supermoons can cause slightly higher-than-normal tides, known as spring tides, because the moon’s gravitational pull is stronger when it’s closer to Earth.
Is a supermoon dangerous?
No, a supermoon is not dangerous. It’s a natural astronomical phenomenon that poses no threat to Earth or its inhabitants.
Can I take good photos of the supermoon with my phone?
Taking quality photos of the supermoon with a smartphone can be challenging but possible. Use a tripod for stability, and experiment with different camera settings, such as reducing exposure and using the zoom function carefully. Using a DSLR camera with a telephoto lens will yield much better results.
What is the difference between a supermoon and a blue moon?
A supermoon refers to a full moon occurring near perigee, while a blue moon refers to the second full moon in a single calendar month, or the third of four full moons in a season.
Summary
The supermoon is a captivating celestial event that offers a unique opportunity to witness the moon at its brightest and largest. Whether you’re an avid astronomer or simply enjoy gazing at the night sky, the supermoon is a sight to behold. By finding a dark location and allowing your eyes to adjust, you can fully appreciate this special lunar phenomenon in Seattle’s skies.
