City light hides most of the show. Drive until the sky looks clearly darker (often 30–60 minutes out), away from streetlights, with an open view.
🛰️ Also crossing the sky that night
Bright ISS and Starlink passes during the best hours appear about five days before.
Shooting stars streak across the sky: up to about 20 an hour from a dark place, fewer this year in bright moonlight.
How to watch
- Find a dark place away from city lights and give your eyes 20 minutes to adjust.
