Comet C/2023 A3 will be visible in the sky over the next few days for more than an hour shortly after sunset each night. For those in Pennsylvania, the sun sets around 6:25 p.m., so the best viewing starts around 7:10 p.m. The comet will be visible for about 90 minutes before it dips too low.

Rice goes on to tell WRAL that the third week of October is optimal for viewing. Look west 30 to 60 minutes after sunset from a dark spot. You may need a telescope to view, but some darker areas could potentially see it dimly lit.

N​ow is your once-in-a-lifetime chance to view one spectacular comet soaring across the night sky. Comet Tsuchinshan-Atlas, also known as comet A3, is visible across the U.S. tonight through Oct. 24.
