Sentinel Stargaze: Star Party Trails


April 17, 1999

In this wide-angle view of the star party site, looking west, we see the city glow of Yuma on the horizon. The bright star trail on the left is Sirius. In the center is the constellation Orion; above Orion is Procyon. The brightest streak to lower right is the setting planet Venus. Notice how the stars in Orion's belt make straight streaks, because they are on the celestial equator. The stars to the right curve around the north celestial pole; the stars to the left curve around the south celestial pole. People walking among the vehicles with red flashlights illuminated the foreground.
