The First Quarter appears at approximately seven days after the New Moon.
At New Moon ; The Earth, Moon, and Sun are in a straight line in that order. Sometimes you see a Solar Eclipse, but other wise the Sun is too bright to see the Moon's sillouette against the Sun.
After seven days, the Moon is at half of its distance between New Moon and Full Moon. So we see only Half The Moon.
The fact that its named the First Quarter suggests a misunderstanding. The word Quarter means it has travelled one quarter of its orbit between New Moon and the next New Moon, but it has travelled half of its orbit
between New Moon and Full Moon.
In orbiting between Full Moon to the next New Moon, it travels the same distance on the other half of its orbit, and you see the LAST Quarter Moon.
Try an experiment. In a darkened room, have a pin-point light(Sun) and shine it on a ball. Between you , the ball, and the light is the New Moon. Now turn yourself and the ball 90 degrees (right angle) and you will see half the ball, the other half is in darkness (first quarter). Turn a full 180 degrees from the pin-point light (your back to the light),and you see the ball fully lit(Full Moon). Turn a further 90 degrees (270 degrees) and you will see the other half of the ball (Last Quarter), and finally back to the next New Moon.
Hope that helps!!!!
It is most difficult during the New Moon as there is no moonlight.
The First Quarter Moon is the phase of the Moon which is most easily spotted by the casual observer. You see the Moon in this phase in the south as the Sun sets. If the sky is clear at sunset, you can't miss the first quarter Moon. In this phase, the Moon sets at midnight. In a crystal clear sky, you can even see the first quarter Moon a few hours before sunset in the southeast.the cicle is new moon, waxing crescent,first quarter, waxing gibbous, full moon, waning gibbous, last quarter, waning cresent,then new moon again and so on so a first quarter moon is when you can't seehalf the moon.
Neap tides are the ones that coincide with the Moon's First Quarter and Third Quarter.
At the time of the "First Quarter" and "Third Quarter" phases, the moon appears half-illuminated. These occasions are roughly 7 days and 21 days after New Moon respectively, and Full Moon occurs at the time exactly midway between them. Note: Both phases are easily visible in the daytime. First Quarter rises in the east around Noon, and Third Quarter sets in the west around Noon.
"First Quarter" and "Third Quarter" are two of the eight names given to the moon's phases.
First quarter and last quarter appear as a half moon. about halfway down this page are some pictures: http://www.calculatorcat.com/moon_phases/moon_phases.phtml
Assuming you're asking how often a "half moon" appears, a half moon (First or Third Quarter moon) will usually occur every 14-15 days (half a lunar month).
The First Quarter moon brings half of the moon. That is what it also looks like.
A first quarter moon is different from a waxingcrescent because a first quarter moon is half full of the the moon and a waxing crescent in only a little wedge of the Moon
because the moon is one quarter size of the earth.
The first quarter moon is the third phase of the moon in each cycle. It rises at noon and is very high overhead at sunset. The first quarter moon sets around midnight.
first is the full moon then it is the last quarter then it is the new moon and the last one is the first quarter
first quarter of the moon is second phase of the moon. it means that the shape of the moon is growing to the waxing gibbous.
the cicle is new moon, waxing crescent,first quarter, waxing gibbous, full moon, waning gibbous, last quarter, waning cresent,then new moon again and so on so a first quarter moon is when you can't seehalf the moon.
New moon, first quarter, full moon and third quarter.
There is the new moon, first quarter, full moon, and third quarter.
It is half the moon.
