“Supermoon” Night Over San Francisco

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 full moon on March 20-21, 2019 brings us the final “Supermoon” of 2019 – the first such supermoon to land on the first day of spring since 2000. Read more on EarthSky.

Best chance for photos of the Supermoon: Moonrise/Moonset
As long as weather corporates, the best time to take photos of a Supermoon is either right around moonrise or moonset as the moon will be closest to the horizon, so you can see the moon relative to hills, trees or buildings for a frame of reference.

  • Wednesday 3/20 Moonset – 7:19am
  • Wednesday 3/20 Moonrise – 7:13pm
  • Thursday 3/21 Moonset – 7:55am
  • Thursday 3/21 Moonrise – 8:25pm

Although the moon appears full for a few to several nights in succession, the moon is only truly full for a fleeting instant – when the moon lies 180 degrees opposite the sun, from the vantage point of Earth.
