The Big Dipper and the Constellations of the Northern Sky

  • Arthur Upgren


In the United States and in Europe, summer sunsets occur quite late in the evening, especially in areas that observe daylight saving time. Twilight lingers and often the sky is not fully dark until after ten o’clock. In the summertime the brightest part of the sky at dusk is always found toward the northwest horizon. With this in mind, one can determine the other compass points easily. If the sky is completely dark when first observed, another reference point must be used.
