Today:
The Big Dipper, found dangling by its handle in the northwest, is known by a number of other names. In England, as well as parts of eastern Europe, it is called the Plough, lowering into the north each fall to till in the crops, as well as a cart or wagon wheeling around the northern sky.
Tuesday:
At 10:15 this evening, the Scorpion’s tail is due south, extremely low above the horizon, yet even so, at its best viewing of the year. As the tail curls up to the left, the star on the end is called Shaula, from the Arabic meaning either “stinger” or “raised”, as in poised to sting.
Wednesday:
Look high in the northwest, as the sun sets. Again as if hanging by its handle, the Big Dipper hangs in the sky. Focus on the arcing shape of the Big Dipper’s handle. Now imagine a continuation of it, and that longer arc will lead you to the star Arcturus, hence the phrase “arc to Arcturus.”
