When you determine whether the moon in the sky is the high or low moon, you can learn many other things such as what phase the moon is in, how the tide will move, and where the moon is. compared with the earth and the sun. Knowledge of where the moon rises and falls during the different phases is also helpful if you want to observe the moon one night. The upper moon has a larger rate of illumination (when observed through the night), that is, the moon is getting fuller. The lower moon is the opposite of the upper moon. There are several ways for you to know whether the moon you are observing is the supreme or the sublime moon. The details may vary slightly depending on where you are on earth, but the basic method is the same.

Steps

Part 1 of 3: Understanding the phases of the moon

1. 

   
   
   Learn the names of the moon phases. The moon revolves around the earth, and then we see many different angles of the illuminated part of the moon. The moon does not glow on its own, but only reflects light from the sun. As it moves from crescent to full and back again, the moon undergoes phases, identified by the crescent and crescent moon shapes created by the moon's shadow. The moon has the following phases:
   • New moon
   • Crescent moon early month
   • The first half of the month
   • The first half of the month moon
   • Full moon
   • Full moon at the end of the month
   • The last half of the month
   • Crescent moon last month
   • New moon

2. 

   
   
   Understand the meaning of the phases. The moon moves in the same orbit around the earth each month, so it experiences the same phases every month. The moon phases are due to our view from the earth. We see that the illuminated part of the moon changes differently as the moon moves around the earth. Remember that half the moon is always illuminated by the sun: the angle from the earth determines the phases of the moon we see.
   • During the new moon period, the moon is positioned between the earth and the sun, so from our perspective the moon is not illuminated. At this point, the illuminated part of the moon is completely towards the sun, and we will see the dark part of the moon.
   • During the first half of the month we see the illuminated half and the unlit part of the moon. This also takes place during the last half of the month, except for the faces seen in the opposite direction.
   • When the moon is full, we see the entire illuminated part of the moon, while the dark is completely outward.
   • After the full moon period, the moon resumes its journey back to the original position between the earth and the sun, starting a new moon phase.
   • The Moon took more than 27.32 days to complete a revolution around the earth. However, one moon month (from one new moon to the next) is 29.5 days, because that is the time it takes the moon to return to its position between sun and earth.

3. 

   
   
   Find out the reasons for the first and last half moons of the month. On the journey from the new moon to the full moon, we will see an increasing proportion in the illuminated half of the moon, and this phenomenon is called the full moon. As we move back from the full moon to the new moon, we will see a shrinking ratio in the illuminated half of the moon; This phenomenon is called a waning moon.
   • The phases of the moon are always the same, so even though the moon may appear in different positions and directions in the sky, you can still determine which phase the moon is in if you know it. close what.

Part 2 of 3: Determining phases of the moon in the northern hemisphere

1. 

   Know that the moon is gradually rounding and waning from right to left. The different parts of the moon are illuminated during full and fading moons. In the northern hemisphere, the illuminated part of the moon grows from right to left until the full moon, then gradually smaller from right to left.
   • The full moon (the hypotenuse) will be illuminated on the right side, and the waning moon (the low moon) will be illuminated on the left side.
   • Raise your right hand with thumb facing out, palms facing the sky. The thumb and fingers form an arc like an inverted C. If the moon matches this arc, it is the supernatural (gradually rounded) moon. When you repeat this with your left hand and the moon matches the "C", it's a low (fading) moon.

2. 

   Remember rules D, O, C. The moon has always followed the same law of illumination, so you can use the shapes of the letters D, O, and C to identify the upper and lower moon. In the first half-moon phase, the moon looks like a D-shape. When the moon is full, the moon looks like an O-shape. And in the last half-moon phase, the moon looks like a C-shape.
   • A crescent shaped moon like the inverted C is a full moon (upper shadow).
   • A crescent moon shaped D is the full moon (upper shadow).
   • A crescent moon with an inverted D is the gradual waning (low hypotenuse) moon.
   • A crescent shaped moon like the letter C is a waning (lower hypotenuse) moon.

3. 

   Find out when the moon rises and sets. The moon's rise and fall times are not always the same, but vary depending on the phase of the moon. This means that you can rely on the time the moon rises and falls to determine if it is a high or low moon.
   • You cannot see the new moon, because then it is not illuminated by the sun, and because the time the moon rises and sets is the same as the sun.
   • As the upper moon gradually turns into the first half of the month, the moon rises in the morning, peaks at sunset and sets around midnight.
   • The full moon rises when the sun sets and sets when the sun rises.
   • When the summer moon turns to the last half of the month, the moon will rise at midnight and set in the morning.

Part 3 of 3: Determination of the phases of the moon in the southern hemisphere

1. 

   Learn about the moon's illuminated parts during the upper and lower moon periods. In contrast to the moon seen from the northern hemisphere, the moon viewed from the southern hemisphere will be illuminated from left to right, fully rounded and then progressively smaller from left to right.
   • The upper moon is somewhat illuminated on the right, the low is somewhat illuminated on the left.
   • Raise your right hand with thumb facing out, palms facing the sky. The thumb and fingers form an inverted C-shaped arc. If the moon fits in this arc, it is the hypnotic (waning) moon. If you repeat this with your left hand, and the moon matches the "C"-shaped arc, it's a supernatural (gradually rounded) moon.

2. 

   Remember the rules of C, O, D. Moon seen in the southern hemisphere will undergo all of the same phases as we see it in the northern hemisphere, but the order of letters will be reversed.
   • A crescent shaped moon like the letter C is a full moon (upper shadow).
   • The crescent moon has an inverted D-shape, which is the full moon (upper shadow).
   • The full moon has an O shape.
   • A crescent moon shaped D is a gradually waning (hypotenuse) moon.
   • A crescent shaped moon like an inverted C is a waning moon (lower hypotenuse).

3. 

   Find out when the moon rises and sets. Although the illuminated portion of the moon seen from the southern hemisphere would be the same as when viewed from the northern hemisphere, the time when the moon rises and falls in the two hemispheres is in the same phase.
   • The first half-moon of the month will rise in the morning and set around midnight.
   • A full moon rises and sets which coincides with sunset and sunrise times.
   • The last half moon of the month will rise at midnight and set in the morning.
