Can you see Mercury and Venus now, in the western twilight after sunset? It depends on how far north or south you reside on the Earth's globe.

As it orbits Earth once a month, the moon is up during the day half the time, pale against the blue sky. You can see it this weekend, if you look.

The legacy of the Harvest and Hunter's Moons are the grand procession of moonlit nights in the season of waning daylight. In 2019, watch for the full, or nearly full moon, around October 11, 12, 13 and maybe even 14.

East quadrature is a hallmark in the ever-shifting 3-D relationship between Earth and another planet. It means, as seen from Earth, the planet is 90 degrees east of the sun. Saturn will reach that point on October 7, 2019.

Tonight - October 5, 2019 - the moon will be at or near its first quarter phase, coupling up with Saturn on the sky's dome. What's more, the lit side of the moon will be pointing at the blazing planet Jupiter.

They are the 2 brightest objects in the night sky now, the moon and Jupiter, closest October 3. By October 4, the moon has moved away, but you'll still notice Jupiter as the bright object nearby.

As September ends and October begins, you'll find the moon back in the evening sky. Look west shortly after sunset!

These upcoming mornings - September 26 and 27, 2019 - the old waning crescent moon and the star Regulus adorn the eastern sky before sunrise.

In most years, Fomalhaut appears solitary. In 2019, however, Fomalhaut has company in the evening sky. The bright planets Jupiter and Saturn are up there, too, pointing the way to Fomalhaut on the sky's dome.

September 22 is the equinox. The word means "equal night." Days and nights are nearly equal now at the equinox, but not quite. Here's why. Also, we've got a new word for you, "equilux." It's the word for when day and night are, in fact, equal.
