Are you looking for the moon and not finding it? That’s because the moon is now in a waning gibbous phase: less than full but more than half-lighted. It’s rising later at night and appearing in the predawn sky and in the sky after sunrise. Last quarter moon will come on June 17, 2017 at 11:33 UTC. (Translate to your time zone here).
A waning gibbous moon initiates a rash of questions about seeing the moon during the day. If it rises late at night, you know the waning gibbous moon must set after sunrise.
In fact, in the few days after full moon, you’ll often see the waning gibbous moon in the west in early morning, floating against the pale blue sky.
What else can I say about a waning gibbous moon? Only that it can surprise you if you happen to be out late in the evening. It rises eerily some hours after sunset, glowing red like a full moon when it’s near the horizon.
Sometimes it looks like a misshapen clone of a full moon.
