“Supermoon” Night Over San Francisco | Full Worm Moon
Submitted by the Event Organizer
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.
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.
The best time to view the super moon is when it’s near the horizon either at moonrise or moonset so that you can view it in comparison to hills, buildings or bridges.
- Moonrise – March 9 – 7:27pm
- Moonset – March 10 – 8:24am
