Biggest Full Moon of the Year

Tomorrow night’s full moon will be the biggest and brightest of the year.


If you think tonight’s Moon looks unusually big, you’re right. It’s the biggest full Moon of 2010. Astronomers call it a “perigee Moon,” some 14% wider and 30% brighter than lesser full Moons of the year

“Perigee” is the point in the moon’s orbit when it’s closest to the Earth, about 50,000 kilometers closer, actually. So if you’re lucky enough to live in an area with clear skies tonight, take a look at that big, beautiful moon up there. Here in Oregon it’d take a miracle, but stranger things have happened.

    It was huge and fabulous here in the Northeast – my 8-y.o. nephew got a great photo of it, which I’ll pass along if he’ll send it to me.

    It was raining here (quelle surprise!). This is one of the worst places to live if you’re an astronomer. Makes New Mexico look better and better.

    My brother The Chemist roots for West Virginia – he sez that in Monangaheala (sp?) in the Blue Ridge Mountains, you can see more stars at night than just about anywhere in the U.S.

    Interesting. The East Coast in general suffers from light pollution like almost nowhere else on the globe. You can see a map of the U.S. at night here. Maybe the Monongahela is far enough away from population centers to be shielded by the mountains from most of the light.

    Out here if I even go up to Mt. Hood, or out to the coast it’s an amazing difference in how many stars are visible. You can’t even see the Milky Way from my town, but head west or east, away from Portland (or even south towards Eugene) and the difference is jaw-dropping.

    Yah – the diff between our place in the Catskills and our home in the suburbs is equally amazing.

  6. Digital Dame says:

    Oh, I can just imagine! I know the difference I see here just going up to Mt. Hood, which is still fairly close to Portland, but the light doesn’t seem to penetrate that far.
