In the Night Sky

NIGHT SKIES IN OCTOBER

 

From October to December we have a new season to live in.

The sky has made another quarter turn around the sun and the joys of Spring are upon us.

Southward,  we feel the Night Sky is on the barren side as the Southern Cross is barely visible from our vista, though soon to rise clockwise again.

The Milky Way along with the Teapot in Sagittarius has moved westward. Scorpius is barely to be seen in the western sky, the redness of Antares glows close to the horizon.

The stream of ‘Time’ flows ever forward while we herald the renewal of constellations in the east.

In the north the great Square of Pegasus hangs above leading Andromeda and Triangulum ever onward.
