A glowing supermoon will light up the sky this week, for the last time in 2019.
A full moon occurs when the sun shines all the way to the moon facing our planet. This is what is called a "super-moon" when it is full and also in perigee. This is where the celestial object is closest to the Earth in its elliptical orbit. This makes the moon appear a little bigger and brighter than normal to the naked eye.
The moon was at its perigee at 3:47 pm EDT on Tuesday. At this point it was 223,306 miles from Earth. The orb should be the most visible of our planet at 9:43 pm. EDT on Wednesday.
Viewers who wish to observe the phenomenon can connect to the live broadcast below, broadcast by the Slooh robotic telescope service from 14:00. EDT (or 11:00 am PDT and 18:00 UTC).

The March full moon will also be the first of the spring equinox, which marks the beginning of spring in the northern hemisphere and the fall in the southern hemisphere. The equinox occurs about four hours before the full moon, according to AccuWeather.
The first spring moon in the northern hemisphere is also known as the "worm". It is thought to be named after the sight of earthworms appearing in warmer, moister soil in the spring, says Space.com.
Walter Freeman, assistant professor in the physics department of Syracuse University in New York, said Newsweek: "The best spots [to see the moon] are places where it is more likely to be clear, especially in the West. The full moon is bright enough to overcome the light pollution of cities in all cities, with the exception of the larger ones. "
Astronomer Gianluca Masi of the Virtual Telescope Project said that the moon would appear 7% larger and a little brighter than an average moon, but that occasional astronomers will not recognize it at first sight.
He continued: "This super-moon is something special, having the full moon so close to the vernal equinox is relatively rare, the last time it was 19 years ago, in 2000. The next time will be in 2030. to be a supermoon, so the next full moon will be very special, once again offering a wonderful opportunity to stay there and watch the sky. "
Freeman has also offered tips to those wishing to take a snapshot of the event. "Moonlight is only the reflection of sunlight." The long-exposure landscape photographs taken at moonlight night are surprisingly strange, you'll see puffy white clouds and a blue sky, just like during the day.
"However, you will see stars in the middle of the blue sky if the moon is not in the frame and if you are in a clear place," he continued. "Moonlight is weak enough not to completely erase the stars, unlike sunlight, so if you go out with a camera and a tripod during the full moon, try taking a moonlit landscape picture."
The supermoon this week will be the last for 2019 and the third of the year. Supermons also occurred on January 21 and February 19. The latter marked the nearest supermoon, when the object was 221 733 miles from the Earth.
According to EarthSky.com, two supermoons of the new moon, probably less exciting, will occur on August 1 and 30, and September 28. But we will not be able to see them because the illuminated side will of course face the sun.
