“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.

On March 9th, the Moon will be located on the opposite side of the Earth as the Sun and its face will be will be fully illuminated. This phase occurs at 10:47 am pst.*

This full moon was known by early Native American tribes as the Full Worm Moon because this was the time of year when the ground would begin to soften and the earthworms would reappear.

This moon has also been known as the Full Crow Moon, the Full Crust Moon, the Full Sap Moon, and the Lenten Moon. This is also the second of four supermoons for 2020.

The Moon will be at its closest approach to the Earth and may look slightly larger and brighter than usual. Although the moon will appear full to the eye on both – March 8 and 9, 2020 – the precise instant of full moon comes to pass on March 9, at 17:48 Universal Time.

*Please note, the full moon occurs at a precise moment in time, i.e. the instant when the Sun and the Moon are aligned on opposite sides of Earth; therefore in March 2020, this time happens to occur in the daytime, but rest assured, the moon still appears full when it rises that evening.
