Tonight, at mid-northern latitudes, look for the brilliant star Arcturus to climb over your eastern horizon around 9 to 10 p.m. local time. That’s the approximate time on your clock, no matter what is your longitude. South of the equator, this northerly star rises considerably later in the evening. Click here to know when Arcturus rises into your sky.
Extend the natural arc of the Big Dipper handle to verify that you’ve found Arcturus. The Big Dipper can actually be seen from as far south as the tropical and subtropical regions of the Southern Hemisphere. However, the Big Dipper doesn’t reach its high point for the night in late February until an hour or two after the midnight hour.
Use Big Dipper to find Polaris, the North Star
In the Northern Hemisphere, Arcturus counts as our faithful springtime star. At present, Arcturus rises about three hours after sunset at mid-northern latitudes. Yet this shining beauty of a star rises about 4 minutes earlier each day whereas the sun sets a bit later daily. All added up, that means Arcurus will be sparkling above the horizon at dusk/nightfall in late March to announce the return of spring to the Northern Hemisphere!
Bottom line: Before going to bed tonight, locate the Big Dipper in your northern sky, and then follow the arc in the Dipper’s handle to find yellow-orange star Arcturus.
