Sirius Sparkles like a Diamond (evening)

In mid-March, the night sky's brightest star, Sirius, or Alpha Canis Majoris, reaches its highest point over the southern horizon at around 8 p.m. local time. Sirius is a hot, white, A-class star. Its location only 8.6 light-years from Earth is part of the reason for its brilliance. For mid-northern latitude observers, Sirius always shines in the lower third of the sky, and therefore through a thicker blanket of Earth's refracting atmosphere. This causes the strong twinkling and flashes of color the Dog Star is known for.
