Supermoon on January 22, 2027 from Seosan

Times are local (GMT+9).
One notification in the late afternoon, only on nights with something worth going out for over Seosan: 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.
Put Seosan's sky in your calendar
Full moons, meteor showers, eclipses and bright ISS passes (with a 10-minute reminder) appear in your calendar and update by themselves.
Plan your night
☁️ Clouds through the night
The hour-by-hour cloud forecast appears about five days before.
🌑 Find a dark sky
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.
A full Moon a little closer than usual, so slightly bigger and brighter.
How to watch
- Watch it rise: near the horizon the Moon looks largest.
- A phone camera on night mode can catch the rising Moon over buildings.
