Can You See Starlink Tonight in Seosan?

Seeing Starlink satellites from Seosan

SpaceX's Starlink satellites orbit about 550 km up and are bright enough to see without a telescope when the geometry is right. At 36.8° N, Seosan is right under the busiest part of Starlink's 53°-inclined shells — one of the best latitudes for catching frequent, high passes that climb steeply overhead rather than just skimming the horizon.

Skies over Seosan are darker than a big metro, so even fainter Starlink passes have a good chance of being visible once your eyes adjust. The best chances come during the dark hours around dawn and dusk, when a satellite high above Seosan is still catching sunlight while the sky around you has already gone dark.

Freshly launched Starlink batches travel close together and appear as a striking "train" of lights moving in a line; as they spread into their operational orbits over the following weeks they become individual moving points. The pass table above already filters for genuinely visible passes over Seosan — sunlit satellite, dark sky, at least 10° above your horizon.

Frequently asked questions

Can I see Starlink tonight in Seosan?

Often, yes. When a Starlink satellite passes over Seosan while it's still lit by the Sun and your sky is dark — around dawn and dusk — it shows up as a steady moving point of light, no telescope needed. The table on this page lists tonight's visible passes for Seosan with the exact time and direction to look.

What time is best to see Starlink over Seosan?

Roughly 1–2 hours after sunset or before sunrise, during twilight, when satellites overhead are sunlit but the ground is dark. Each pass on this page shows its start time in your local zone (Seosan is around UTC+8).

Which direction should I look from Seosan?

Each pass lists where the satellite rises, its highest point and where it sets. Because Seosan is in the northern hemisphere, many passes track across the southern sky, so facing south is a good default — then follow the moving light as it climbs.

Why can't I always see Starlink from Seosan?

Starlink satellites are only visible when sunlight reflects off them while you're in darkness. In the middle of the night they pass through Earth's shadow and vanish, and by day the sky is too bright — which is why visible passes over Seosan cluster around dawn and dusk.
