Today:
Lowering in the west at dusk, you can catch the Crescent Moon and Venus in close proximity, with the yellow/beige Venus just the right of the Moon. As they emerge from the twilight, the two will be diving quickly toward the horizon, disappearing below it a little after 10:00 PM..
Saturday:
The North Star, also known as Polaris, remains anchored halfway up from the northern horizon, never moving noticeably, though, technically, it does make a very small circle as the Earth rotates on its axis. The circle is a little more than one degree, or twice the diameter of the Moon.
Sunday:
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.
