The moon in daylight

A rather shocking number of people (including authors) seem to believe that the moon comes-up and is seen at night; whereas it can rise at any time and (given the right conditions) be seen during the day in all its phases - as shown above in a sequence from Taiwan which was collected over a period of five years by Meiyng Lee. 

The crescent moons (old and new) are at a small angle to the sun, and can only be seen at dawn or dusk - which is why the pictures have a brighter background; and the full moon can only be seen in daylight during afternoon of the summer months (and apparently these are usually misty in Taiwan). Easiest daytime viewing of the moon is when it is about half - afternoons for the waxing-, and mornings for the waning-moon.
