Many of us dreamed to go to the moon and to land there like the first man who step into the moon (Neil Armstrong). It only appears during night time because our planet revolves around it.
It appears during the daytime also, but not regularly.
Tips for Observing the Moon in the Daytime
Observing the moon in the daytime can be a challenge. Finding the moon in the sky is easiest when the moon is at least in a thick crescent phase, and when the sky is totally free from clouds, and the humidity is low. This makes for a nice dark blue sky which which contrasts nicely with the moon. However, the weather doesn't always cooperate to this extent.
To increase your chances of success, try these tips:
Use a Day-time Moon Calendar
to assist you in knowing where and when to look.
The moon will most likely be smaller than you expect at first.
Put your hand in front of the sun while you are looking for the moon. If the moon is to the left of the sun in the sky, then use you right hand, and if the moon is to the right of the sun, use your left.
If the sky is partly cloudy, keep watching in the part of the sky where you expect to find the moon. As the clouds pass by, you'll be able to see the moon intermittently.
To find a thin crescent moon, try moving just into a shadow. Make sure that the correct part of the sky is still visible. Sometimes an overhang at the entrance of a building, or a corner of a building works well.
So, if the Moon is bright enough to be seen by day, why can’t we see it every day?
When the Moon is full, and at its brightest, it sits directly opposite the Sun in the sky, which means it is below the horizon while the Sun is up. The New Moon rises during the day, but sits too close to the Sun to be seen. It sets at night, which is why the night sky is dark during the New Moon. It’s only as the Moon gets close to its quarter phases that the conditions are ideal for it to be seen during the day. That is, it is bright enough, far enough away from the Sun to be seen, and rises or sets during daylight hours. When all of these conditions come together, and when the sky is clear enough, the Moon becomes visible during the daytime.
