Magnitude Charts for the Constellation Bootes at 40N
Compare the view of your nighttime sky to the Magnitude Charts below. This will determine the magnitude of the faintest stars that you can see at your location. For printouts to use during your observation, you can use the magnitude charts included in the Activity Guides. For practice, try the Observation Practice quiz! (requires Flash)
Can you find Bootes?
To find Bootes, look for the Big Dipper constellation in the north. Follow the arc made by the Dipper's handle until you see a bright star. This is Arcturus, which is located in what would be the waist of Bootes. The rest of the stars in Bootes form the shape of a kite, with dimmer stars beneath the diamond shape of the kite forming his legs.
