cheersTONIGHT'S FULL MOON IS A PERIGEE MOON: If you think tonight's full Moon seems a bit bigger and brighter than usual, you're right. It's a "perigee Moon," about 14% bigger and 30% brighter than lesser full Moons we've seen earlier this year. The Moon's orbit is an ellipse with one side (perigee) about 50,000 km closer than the other (apogee): diagram. Perigee moons--a.k.a. "supermoons"--are not unusual. This is the third month in a row we've had one.
A supermoon occurs when the moon is at its closest point to Earth in its orbit, making it appear larger and brighter in the sky. This happens about every 14 full moons, or once every 14 lunar months.
The next supermoon will occur on December 3, 2017, and will be the first and only supermoon of 2017. It will also be the only supermoon visible in the Northern Hemisphere for the entire year.
To observe and photograph the supermoon, find a location with a clear view of the eastern horizon at moonrise. Use a telephoto lens or zoom function on your camera to capture the moon's details. If possible, try to incorporate interesting foreground elements, such as buildings or trees, to add depth to your photos.
A supermoon appears larger and brighter than a regular full moon because it is closer to Earth in its orbit. This phenomenon is also known as perigee-syzygy, as the moon is at its closest point (perigee) and in alignment with the sun and Earth (syzygy).
There are no special precautions necessary when observing or photographing the supermoon. However, it is always important to take safety precautions when going outside at night, such as using a flashlight and being aware of your surroundings. Additionally, make sure to dress warmly and bring any necessary equipment, such as a tripod, for photographing the moon.
