One notification in the late afternoon, only on nights with something worth going out for over Cheonan: a very bright ISS pass, a Starlink train, a meteor shower peak, planets together, a supermoon or eclipse, the northern lights, or a bright comet. Only the city is stored, not your location.

Shooting stars streak across the sky: up to about 150 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.
