"First Quarter" and "Third Quarter" are two of
the eight names given to the moon's phases.
The Moon's third quarter phase, also known as the last quarter, occurs when half of the Moon's visible surface is illuminated and is located between the full moon and the new moon. The first quarter phase, conversely, also features half of the Moon illuminated but occurs between the new moon and the full moon. Both phases showcase the same amount of illumination (50% of the lunar surface), but they are opposite each other in the lunar cycle, with the first quarter appearing in the evening sky and the third quarter in the morning sky.
One lunar month is 29.53 days, the time taken from one new moon to the next. The first quarter is 7.3825 days from the new moon phase, one quarter of the lunar month. That's about 7 days and 8 hours.
The phases called "first quarter" and "third quarter" have those labels because theyoccur one quarter and three quarters of the period of time from one new moon untilthe next new moon.At both of those times, we see half of the moon lit up.
It takes about 29.5 days for the moon to go through all its phases and return to the same phase again, known as a lunar cycle or lunar month.
The moon is always Full at the time of a lunar eclipse.Sun, earth, and moon are in a straight line and in the same plane. The earth is in the middle.The moon is on one side of the earth ... in its shadow ... and the sun is on the other side,about 390 times as far away as the moon.

One week from now, the moon will likely be in the first quarter phase, where half of the moon is illuminated. The new moon phase is followed by the waxing crescent phase and then the first quarter phase in the lunar cycle.
That's Full Moon. If the arrangement is in exactly the same line, then there's a lunar eclipse.
To record the phases of the moon, you can start by observing the moon each night and noting its appearance in a journal. Take photographs or draw sketches of the moon at the same time each evening to capture its changes. You can also use a lunar calendar to mark the dates of each phase, such as new moon, first quarter, full moon, and last quarter. Finally, consider using a moon phase app for real-time updates and additional information.

The amount of the lighted side of the moon you can see is the same during the first quarter and the last quarter phases. In both phases, half of the moon's illuminated side is visible from Earth.
It takes about 29.5 days for the moon to go through all its phases and return to the same phase again, known as a lunar cycle or lunar month.
The moon's phases result from the changing relative positions of the Earth, Moon, and Sun. It doesn't matter where the moon is when it's half-lit (or in its first quarter); its position relative to Earth and the Sun does matter, however. When the Sun and Moon are aligned on the same side of the Earth the Moon is "new", and the side of the Moon visible from Earth is not illuminated by the Sun. As the Moon waxes (the amount of illuminated surface as seen from Earth is increasing), the lunar phases progress from new moon, crescent moon, first-quarter moon, gibbous moon and full moon phases, before returning through the gibbous moon, third-quarter (or last quarter) moon, crescent moon and new moon phases.
Whatever phase the moon happens to be in, it looks the same from every place on Earth where there are people looking at it.
No, lunar phase refers to the changing appearance of the Moon as seen from Earth due to its position relative to the Sun. Mitosis is a cellular process where a cell divides into two daughter cells, each having the same number of chromosomes as the original cell.
