“Supermoon” Night Over San Francisco 2024
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.

September 2024’s “Harvest” full moon is also a supermoon. Plus, it’ll be extra special because there will also be a partial lunar eclipse, visible from North America, which is when the Earth moves between the sun and the full moon without being perfectly aligned. It’ll appear as if someone has taken a bite out of the moon.
The best time to view the supermoon is when it’s at the horizon so that you have buildings, trees, hills or mountains to compare it to when the moon is low on the horizon. So the best viewing times are either just after moonrise or just before moonset, even if it’s not at the exact minute of the super moon’s peak effect.
