Two stars in Scorpius are harbingers of spring

Go ahead. Treat yourself to something beautiful, and hopeful: a glimpse of two stars that represented a Pawnee version of Groundhog Day.

On this Groundhog Day – February 2, 2016 – look east before dawn for another sign of spring. It’s the two stars that represent the Stinger in the constellation Scorpius the Scorpion. From mid-northern latitudes, in the cold dawn of February, the sighting of these stars announces that the winter landscape is about to awaken from its long dormant slumber: that spring is on its way. You’ll need a clear, unobstructed view to the south to southeast to spot Scorpius’ stinger stars – Shaula and Lesath – flickering by the horizon. If you miss seeing these stars tomorrow, or the next day, try again later in February.

If you're in the Northern Hemisphere, Shaula and Lesath will come over your southeastern horizon sometimes this month.  They're a hopeful sign that spring is coming.

For the Pawnee, who roamed the prairie lands of Kansas and Nebraska, the sky was a calendar, and the stars foretold the change of seasons. The Pawnee saw a snake in the stars forming the front part of Scorpius. But the stars of the stinger were, for the Pawnee, a pair of ducks.

It’s thought that the Pawnee called the stars on the Scorpion’s stinger the Swimming Duck stars. When the Swimming Ducks came into view in the southeast – prior to daybreak in the month of February – the Pawnee recognized that it was time to begin planting ceremonies. In other words, they were a sign of hope, and a sign that spring was on its way.

These stars are now coming into view at or shortly before dawn.

In some respects, we can regard the search for the Swimming Duck stars as a Pawnee version of Groundhog Day.

The return of the Swimming Ducks to the morning sky signaled the first stirrings of the great plains from hibernation. Shaula and Lesath’s presence over the horizon was symbolic of waterfowl breaking through the ice.

As we approach the end of winter, Shaula and Lesath will appear higher each morning in the southeast before dawn. Their morning appearance tells us that the prairie is about to awaken to the rolling thunders of spring.

By the way, for us today, the stars at the end of the Scorpion’s tail are also known as the Cat’s Eyes. They’re easy to spot at the J-shaped star pattern that forms the constellation Scorpius.

Bottom line: Go ahead. Treat yourself to something beautiful, and hopeful. Get up early on some morning this February, and look for the Scorpion’s stinger stars near the horizon. If you’re lucky, you might behold them – a first glimmer of spring!
