Through the course of the year the Big Dipper’s position changes as it “orbits” the North Star. During the Fall the Big Dipper is at the bottom of its rotation and sits directly under the North Star at nightfall. For northern mid-latitudes this creates a unique opportunity to see the Big Dipper “sitting upright” on the northern horizon; including us here in Arkansas! For people further south the Big Dipper has set and is below the horizon, those further north and it is higher in the sky above the horizon. For those around 35 deg. North latitude, it sits almost perfectly on the horizon.
Just as the Sun and Moon appear bigger when they are near the horizon, the same holds true for the constellations. Thus you’ll see the Big Dipper appear bigger than normal as it sits there.
In late October look north to see the Big Dipper sitting, as it were, on the Earth.
