root cause

The moon is visible in the daytime because its side facing the earth - like at night - is at least partially illuminated by the sun for most of the time. The albedo (the reflectivity) of the lunar surface is high enough to reflect so much sunlight to the earth that it can be perceived by an observer on the earth's surface despite the sunlight scattered in the earth's atmosphere . Another factor is the very small distance of the moon with only approx. 380,000 km in the comparative scale of the solar system with its relatively large diameter of approx. 3,500 km. If the moon is visible in broad daylight, and how much or in what form, depends, apart from the degree of cloud cover , on the

• Basic brightness of the day,
• from the respective moon phase , i.e. from the position of the moon on its orbit around the earth
• the position from which the moon must be above the horizon .

Moon phases

Diagram showing the times of rising and setting of the moon and the change of moon phases as well as the times of sunrise and sunset for Berlin in March 2018. The areas in which the blue area and the yellow areas intersect indicate periods in which the moon is during the day was visible, provided that the side facing the earth was sufficiently illuminated (see red dotted curve and moon phase symbols). Note that there were two full moons that month, an event known in English-speaking countries as the " Blue Moon ".

The basic rules regarding the phases of the moon for Central Europe (and most other regions of the world) can be that the full moon can only be seen in the morning and evening hours during the day, whereby it rises relatively shortly before sunset in the east and / or in the west sets relatively shortly after sunrise. Crescent phases, on the other hand, can very often be observed in the morning (waning moon) or afternoon (waxing moon). At the new moon the moon is in the sky almost all of the bright day, but because during this phase of its orbit only the side facing away from the earth is illuminated by the sun and because it is relatively close to the sun, it is practically invisible. The very narrow and therefore weakly luminous sickles of the "fresh" waxing (see Hilal ) or the "old" waning moon can only be observed relatively shortly after sunset in the west or relatively shortly before sunrise in the east.
