Write down the approximate time of each month. Science.

6。 The upper semicircle in the figure shows the relative position of each moon phase in the first half of the month and at dusk and sunset. The lower semicircle indicates the relative position of each stage in the second half of the month and at dawn and sunrise. The figures in the picture indicate the time when the phase of each month rises relative to the sun. Everyone faces the south station. Because the moon phase is only visible above the ground level, its trajectory is only a semicircle. The ups and downs of each lunar phase are summarized in the following table:

Comparing the appearance of the moon phase with that of the sun, the time when the moon phase can be observed theoretically on the earth → the time when the moon can actually be observed on the earth → the moon and the new moon (the first day) rise and fall together at 6 o'clock → 18 o'clock, and the moth moon (the third and fourth days) rises late and sets at 9 o'clock →2 1 o'clock → 2/kloc-0. 8) Get up in the evening and then set at 12 →24: 00, that is, 0: 18 →24: 00 and 6-hour full moons (the first 10 and the first1day) and then set at/kloc-0. Kloc-0/6) gets up early at 18 o'clock →6 o'clock (visible all night) at 65438 convex moon (19, 20), and 2 1 point falls first →2 1 point 9 o'clock → last quarter moon (22 The moth eyebrow moon (26th and 27th) rises early and sets at 3: 00 → 15: 03 →6: 03. As can be seen from the table, the phases in the first half of the month all rise during the day and fall at night. In the second half of this month, the moon rises at night and sets during the day. Therefore, the first half of the moon phase can be seen after sunset and the second half can be seen before sunrise and dawn.
