Event Details

“Supermoon” Night Over San Francisco | 2020

Thanks to an optical illusion in the sky, the moon will appear bigger and brighter than normal in the San Francisco Bay Area in the night, during what astronomers call a “supermoon.”

Because the sun is about 50,000 miles closer to the earth than at its furthest point – and it’s a full or new moon – the moon will appear larger and brighter than most full moons. To be considered a supermoon, it has to be within 224,851 miles (361,863 kilometers) of our planet, as measured from the centers of the moon and Earth.

The best time to observe the supermoon is when the moon is near the horizon during either moonrise or moonset, thanks to having objects in the foreground (like buildings or trees) to provide reference points for estimating the moon’s size.

The closest full moon since 1948 is coming up on November 14th.

Technically the moon reaches its full phase very early on the morning of November 14th. But don’t worry, for taking photographs and just watching in awe the moon should be big, bright and equally awesome to watch on both November 13th and 14th.

Your best best to notice the larger size of the moon is when it’s near the horizon and there’s something to compare it to. So either at moonrise or moonset when you can see it next to the hills, buildings, bridges or coastline. If you just stare at it high in the sky with no frame of reference it’s hard to notice a difference.

So your ideal time for photos will be Sunday evening around 5pm, Monday Morning around 5:30am or Monday evening around 5:40pm
