Can You See Starlink Tonight in São João da Boa Vista?

Seeing Starlink satellites from São João da Boa Vista

SpaceX's Starlink satellites orbit about 550 km up and are bright enough to see without a telescope when the geometry is right. São João da Boa Vista sits at a fairly low latitude (22.0° S), well inside Starlink's 53°-inclined orbital shells, so satellites can climb high overhead and cross the sky in almost any direction. Passes here are often steep and bright when the geometry lines up.

Skies over São João da Boa Vista 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 São João da Boa Vista 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 São João da Boa Vista — sunlit satellite, dark sky, at least 10° above your horizon.

Frequently asked questions

Can I see Starlink tonight in São João da Boa Vista?

Often, yes. When a Starlink satellite passes over São João da Boa Vista 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 São João da Boa Vista with the exact time and direction to look.

What time is best to see Starlink over São João da Boa Vista?

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 (São João da Boa Vista is around UTC-3).

Which direction should I look from São João da Boa Vista?

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

Why can't I always see Starlink from São João da Boa Vista?

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 São João da Boa Vista cluster around dawn and dusk.
