Watch after sunrise for a daytime moon

The Northern Hemisphere’s full Hunter’s Moon has passed. The moon is now in a waning gibbous phase, rising in the east later and later each evening. That means you can catch the moon over your western horizon after sunrise in the coming days. Sylvia asked:

When is the best time to see the moon in the sky during daylight hours?

The answer is that the daytime moon is up there much of the time, but, because it’s pale against the blue sky, it’s not as noticeable as the moon at night. The most noticeable moon at night is a full moon. The recent full moon was on October 24 at 16:45 Universal Time; translate to your time zone. That means the time is now to catch a daytime moon, in the west in the morning.

Jacob Zimmer caught this daytime moon on January 12, 2017 from Clearwater Beach, Florida.

Every full moon rises around sunset and sets around sunrise. But now the moon is in a waning gibbous phase – rising later each night – and setting in the west later each day after sunrise.

So, in the several mornings after full moon – after sunrise – look for the waning gibbous moon in the west during the morning hours. At mid-northern latitudes in North America, the moon will set well nearly two hours after sunrise on October 26, 2018, and will set an one hour (or more) later each day thereafter.

Marcy Fisher wrote on October 7, 2017: “I just took this in Ocala, Florida. It was a nice beautiful surprise.”

By the way, the moon is up during the day half the time. It has to be, since it orbits around the whole Earth once a month. A crescent moon is hard to see because it’s so near the sun in the sky. At the vicinity of last quarter moon about a week from now, you might have to crane your neck, looking up, to notice it after sunrise.

Ordinarily, we don’t look up to see the waning last quarter moon and waning crescent after sunrise. That’s one reason why people so often miss the moon during the day.

Day by day, the lighted portion of the waning gibbous moon will shrink and the half-lit last quarter moon will come on October 31. Watch for the daytime moon to climb higher and higher into the western sky after sunrise all this coming week!

Look for the moon in your eastern sky before going to bed this evening, on October 25, and then seek for the moon in your western sky before sunrise October 26.

Bottom line: Starting around October 26, 2018, look for the daytime moon in the west after sunrise.
