Brightest Star Reflection
At 2AM Sirius was casting a long, shimmering reflection on the Bighorn River just before it set. With a magnitude of -1.5, Sirius is the brightest star in the night sky. And at a distance of 8.6 light years away, it’s the 8th closest to Earth. Under certain atmospheric conditions when it's low on the horizon this star is known to twinkle wildly and flash a wide range of colors. This happens more often than other astronomical objects because of it’s brightness (planets do not twinkle). Sirius is found in the constellation of Canis Major and is also called the Dog Star. The ancient Greeks used to watch for the first appearance of Sirius in July, which marked the beginning of the “dog days of summer,” the hottest part of the year.
