October offers a chance to observe what could be the brightest comet of the year. Earlier this year we got a look at Comet 12P, which was visible with binoculars but not super bright. Now another of these ancient and icy dust balls is streaking through our neighborhood on an 80,000-year orbit from the distant reaches of the Oort Cloud. The comet, known as C/2023 A3, aka Tsuchinshan-ATLAS, is currently speeding through the inner solar system. It passed its closest to the Sun in late September, and will be at its closest to Earth on October 13th. And after that time, through the end of the month, will be the best time to look for it. This is when the comet will become visible low in the western sky beginning during twilight.
