Comet C/2023 A3 – known as Comet A3 for short – was first discovered last year and was first visible in the night sky earlier this month, with the peak of its sighting occurring October 16-20.

The comet is expected to swing through our solar system sometime in 80,000 years and never again.

Is there a comet tonight?

Comet A3 will be visible in the night sky tonight – and for the next few nights – if you know what to look for.

About 45 minutes after sunset, go outside and look in the direction the sun is setting. Use your hand as a guide as to where to look. Hold your arm straight out, make a fist, and align it with the horizon. The comet should be visible at this general point in the sky. Then scan the area and look for a blurry, glowing ball slowly moving across the horizon.
