Orion, Canis Major and Canis Minor, mid-October
Chart Caption – 2025, Mid-October: As twilight begins, Orion and surrounding bright stars are in the southern sky.

Step outside about 90 minutes before daybreak, this is when morning twilight begins.  Look into the southern sky.  At the mid-northern latitudes, Orion – winter’s flagship winter constellation – stands about halfway up in the south.

Orion is easily recognized.  Three bright stars of nearly equal brightness, make a short diagonal line.  They are surrounded by a rectangle, with red-orange Betelgeuse at the upper left and blue-white Rigel to the lower right.

The constellation appeared low in the eastern sky before sunrise about three months ago.  Rising earlier each morning, it is now in the south before sunrise.  Soon it appears in the evening sky after sunset and then in the south during winter.

Sirius, the night’s brightest star, is to Orion’s lower left.  While not as bright as Jupiter, high in the southeastern sky or Venus low in the east, it outshines all other stars this morning.  It is part of the Canis Minor – the Big Dog.

Procyon – the Little Dog Star – is to Sirius’ upper left.

Sirius, Procyon, and Betelgeuse are at the vertices of the Winter Triangle.

Of the 10 brightest stars visible from the mid-northern latitude, Sirius is brightest; Rigel, 5th; Procyon 6th; and Betelgeuse, 7th.

Compared to winter evening sky watching, mid-October provides warmer weather to look south and ponder the wonders of Orion and the surrounding stars.
