This time of year usually stirs up a phone call or email or two involving "first time" sightings of the bright star Sirius, whose brilliant, multi-colored twinkling catches some people's attention at least once in their lives, causing them to gawk and either wonder why they'd never noticed it before, or assume it's a new thing in the sky, some rare and unusual occurrence.
Sirius catches the eye not only because it's the brightest star in the night sky, but also because of its wild and colorful twinkling.
According to Burnham's Celestial Handbook other names for Sirius include "The Sparkling One" or "The Scorching One." The star normally appears a brilliant white with a tinge of blue, but when the air is unsteady, or when it is low to the horizon it seems to flicker and splinter with all the colors of the rainbow.
