Morning Sky

Morning Moon with Leo

Night with the planets
Chart Caption – 2024, November 23: One hour before sunrise, the moon is in the south-southeast with Leo.

An hour before sunrise, the thick waning crescent moon, 46% illuminated, is high in the south-southeast, 6.7° to Regulus’ lower left, Leo’s brightest star.

The moon’s place this morning nearly mirrors the sun’s spot during late summer mornings.

Jupiter in West

A night with the planets
Chart Caption – 2024, November 23: During morning twilight, bright Jupiter is in the western sky.

Bright Jupiter is over 25° above the western horizon, below Taurus’ horns and above Aldebaran, the Bull’s brightest star.  As the planet heads for opposition, it is lower in the sky each morning.

Mars between Jupiter, Moon

A night with the planets
Chart Caption – 2024, November 23: Before sunrise, Mars is high in the southern sky.

Mars is more than halfway from Jupiter to the morning moon.  It is to the upper left of Castor and Pollux.

See Mars, Beehive Star Cluster

A night with the planets
Chart Caption – 2024, November 23: Through a binocular, Mars appears with the Beehive star cluster and Cancer’s stars.

Use a binocular to see it with the Beehive star cluster, a stellar bundle that appears about three times larger than a Full moon, but appears as a cloud to the unassisted eye in a dark location.  Place Mars toward the upper right edge in the field; the cluster appears near the center.  It is in the middle of an irregular box, bounded by Asellus Australis, Asellus Borealis, Eta Cancri (η Cnc on the chart) and Theta Cancri (θ Cnc).  This morning, Mars is 1.0° to Eta’s upper right and 2.9° to the right of the cluster.

More stars are visible in the cluster when observed before twilight begins and when the moon is out of the sky.

Evening Sky

Night with Planets Begins after Sunset

A night with the planets
Chart Caption – 2024, November 23: One hour after sunset, brilliant Venus is in the southwestern sky.

A night with the planets begins after sunset.  Brilliant Venus is visible in the southwest even during bright twilight.  As darkness falls, the Evening Star is easy to see. 

By one hour after nightfall, Venus is nearly 15° above the southeast horizon. It is 2.0° to the upper left of Nunki, in the handle of the Teapot, the brightest stars in Sagittarius.  Use a binocular to see the star with the planet.

Mercury retreats into brighter twilight.  While the planet sets over an hour after sundown, it is dimmer than it was a week ago, and less than 5° above the horizon at 30 minutes after sundown.  The speedy world is overtaking Earth, reappearing before sunrise later next month.

Saturn, Neptune

A night with the planets
Chart Caption – 2024, November 23: During evening twilight, Saturn and Neptune (use a binocular) are visible in the southern sky.

When Venus is in the southwest, look for Saturn less than halfway up in the south-southeast.  While not dazzling like Venus, the Ringed Wonder is the brightest star in the region.  It is about 20° to the upper left of Fomalhaut, the mouth of the Southern Fish.

Planets Uranus and Neptune
Chart Caption – 2024, November 2: Through a binocular, bluish Neptune appears near 20 Piscium (20 Psc) and 24 Piscium (24).

With the waning moon visible later during the night, try to find Neptune with a binocular.  It is over 14° to Saturn’s upper left, in front of a dim Aquarius’ starfield.  Through a binocular, Neptune appears as a bluish star near the stars 20 Piscium (20 Psc on the chart) and 24 Piscium (24 Psc).

Jupiter

A night with the planets
Chart Caption – 2024, November 23: Three hours after sunset, bright Jupiter is in the eastern sky.

Jupiter rises less than an hour after sunset.  When they are near the horizon, Jupiter and Venus are bright enough to shine through the atmosphere’s filtering effects.  Within 30 minutes of Jupiter’s rising, look for the night sky’s two brightest starlike bodies in opposite directions, Venus in the southwest and Jupiter in the east-northeast.  Find a clear horizon looking in their directions.  Watch Jupiter seem to rise higher and Venus set.

By three hours after nightfall, Jupiter is over 20° above the eastern horizon. It is between Taurus’ horns, Elnath and Zeta Tauri.  The Jovian Giant retrogrades – appears to move westward against the starry background.  Tonight, it is 9.3° to topaz Aldebaran’s lower left, the Bull’s brightest star.

Uranus through Binocular

A night with the Planets
Chart Caption – 2024, November 23: Planet Uranus appears in the same binocular field with the Pleiades star cluster and the stars 13 Tauri (13 Tau) and 14 Tauri (14 Tau).

Planet Uranus is in the same binocular field with the Pleiades star cluster.  It is easy to see to the west of the stars 13 Tauri (13 Tau on the chart) and 14 Tauri.  Look for it when it is higher in the sky and before the moon rises, over six hours before sunrise tomorrow.

Mars at End of Night with Planets

A night with the planets
Chart Caption – 2024, November 23: Six hours after sunset, Mars is below Pollux in the eastern sky.

Mars, about the same color as Aldebaran, but dimmer, rises about three hours after Jupiter.  Before midnight and six hours after sunset, the Red Planet is nearly 20° up in the east-northeast, over 12° below Pollux, one of the Gemini Twins.

As the sky appears to move westward, Saturn sets in the west-southwestern sky.  Jupiter and Mars appear farther westward.  During twilight tomorrow morning they are nearly in the same place in the sky as this morning.
