The Celestial Sphere from Latitude 45° North

The sky from 45°N at 1300 hours sidereal time

This page contains a description of the stars, constellations, and deep-sky objects that can be seen in the sky at around 1300 hours sidereal time. It is assumed that the observer is located at approximately 45° latitude north.

To use the sky map, orient it so that the direction you are facing is at the bottom of the map. Zenith, the point directly overhead in the sky, is located at the centre of the map.

Looking North

Due north and very close to the horizon is the W-shaped constellation Cassiopeia. Directly above her is Ursa Minor with Polaris taking on its role as 'pole star'. This 'Little Dipper' appears to be standing almost upright on its handle in contrast to the 'Big Dipper' above it. This asterism, part of the constellation Ursa Major, is hanging upside-down high in the sky. Mizar, the star marking the bend in the handle of the 'Big Dipper', is practically at zenith. Look for its faint companion star Alcor.

There are a number of bright stars nearing the horizon in the west and northwest. Castor and Pollux, the Gemini twins, are diving for the ground in the west whilst the bright yellow star farther around to the north is Capella in the constellation Auriga.

Bright stars are appearing in the east and northeast as well. Deneb marks the tail of the swan in Cygnus which is hovering just above the northeastern horizon. Higher still is bright Vega in Lyra. Draco always keeps a close eye on Vega as the 'lozenge' of stars outlining the dragon's head is close to Lyra.

Looking South

Few bright stars or bold constellations grace the southern skies. Rising in the east is Ophiuchus with his snake Serpens. Hercules is high in the eastern sky, its 'Keystone' containing M13, the Great Globular Cluster. It appears as a faint smudge in the constellation but resolves into a spherical cluster of aging stars when observed with a telescope. The small but easy to see half-circle of stars making up Corona Borealis lies next to Boötes. Boötes looks rather like a kite or ice cream cone and the bright star it its bottom point is Arcturus.

Below Arcturus is another bright star seemingly all by itself. This is Spica in Virgo. Faint Libra is just coming up over the southeastern horizon but Leo, on the other side of Virgo, is high in the sky. Regulus marks the heart of the lion and lies at the base of the 'Sickle' of Leo. Cancer with its Beehive Cluster (M44) is sinking in the west, chasing Procyon of Canis Minor before it.
