Comet A3 in the Evening Sky?

10/17/2024

This is your second once-in-a-lifetime chance to spot Comet C/2023 A3 (Tsuchinan-Atlas). As the comet makes its closest approach to Earth, opportunities to spy it will flip from the pre-dawn to the early-evening.

As soon as it's dark, look west, low on the horizon. You might have to gain some elevation if your horizon is obstructed. If you can't see the comet directly, try using your peripheral vision (or binoculars).

Astrophotographers: note that this comet is FAST. Relative to the Earth, it's cruising through our solar system at 81 kilometers per second. The rotation of the stars will seem slow in comparison!
