□ Full moon occurs when we can see the entire lit portion of the Moon. The waxing gibbous phase occurs between the first quarter and full moon phases. □ Waxing gibbous moon is when more than half of the lit portion of the Moon can be seen and the shape increases ("waxes") in size from one day to the next. It occurs approximately a week after new moon. □ First quarter moon occurs when half of the lit portion of the Moon is visible after the waxing crescent phase. □ Waxing crescent moon occurs when the Moon looks like crescent and the crescent increases ("waxes") in size from one day to the next. A solar eclipse can only happen at new moon. The new moon phase occurs when the Moon is directly between the Earth and Sun. □ New moon occurs when the Moon cannot be seen because we are looking at the unlit half of the Moon. The 4 main phases are New Moon, First Quarter, Full Moon, Last Quarter. Wondering what's the moon phase today? The moon rotates around the Earth every 29.5 days in an elliptical shape, and due to lunar apogee and perigee, each quarter phase can vary slightly in duration, but is commonly approximated at 7.4 days. As such, illumination can vary from 0% (new moon) to 100% (full moon). Various factors determine moon phase such as the position of the moon in its orbit, the Earth's position around the Sun shift, and the age of the moon in its synodic month. Lunar phases gradually change over the next 29.53 days, also known as a synodic month. The phase of the moon is bascially the shape of the sunlit portion as viewed from Earth. Since the timespan between moonrises and moonsets is a little longer than 24 hours, some days may just miss the cutoff and not have a rise or set that day. On some days, the Moon may not rise or set due to the fact that the moon is constantly in motion. Please note that time and direction of moonrise/moonset differs if there are mountains or other obstacles in the way, as we assume a flat surface with no obstructions. Moonrise and moonset can vary, and are based on the geographic Latitude and Longitude. Moonset occurs when the upper edge of the Moon's disk touches the horizon. Moonset is typically defined as the instant when the moon is no longer visible in the horizon. They will bring a variety of telescopes and point them towards the skies to offer an up-close and in-depth look at the supermoon eclipse.Closeup of the moon © / Gudella Moonrise is typically defined as the first appearance of the moon over the Earth's eastern horizon, or when the upper edge of the Moon's disk touches the horizon. Georgia Tech’s School of Physics will host a viewing event Sunday evening open to the public on Tech Green. Sowell gave us this approximate timing:ġ0:11 pm: Moon moves into totality, being completely covered by earth’s shadow.Īround 11:30 pm: Moon will begin moving out of shadow. That puts Georgia and Atlanta on the front row.ĭr. Because of the earth’s alignment the Eastern Unites States is in prime position for viewing. It’s happening early enough in the evening that many people will be able to see it. There is another nice thing about this eclipse in particular. This eclipse is happening at time when the moon is nearest to earth, making it appear larger and brighter. “There are times in the moon’s orbit where it’s a little bit closer to the earth.” “The moon’s orbit is not exactly circular,” Dr. So what makes this eclipse even more super? The only time the moon goes into the shadow is during an eclipse,” he explains. A lot of people think that the moon goes through phases because it’s going into the earth’s shadow, but that’s not the case. “A curved shadow moving slowly across the moon. Jim Sowell from the Georgia Tech School of Physics explains what you’ll be able to see with the naked eye. What it is being referred to as may sound like something ripped from a superhero comic book: The supermoon lunar eclipse.Īstronomer Dr. Eyes will be on the skies Sunday night, for a rare celestial event.
