STARLINK-5691 — Live Satellite Tracking (NORAD 55478)
Track STARLINK-5691 (NORAD catalog number 55478) live on the WatchSat interactive 3D globe above. Its position is propagated in real time from the latest CelesTrak two-line element set using the SGP4/SDP4 orbital model — the same math professional trackers run. It is object AF of 2023's 15th orbital launch (COSPAR designation 2023-015AF). It went up together with 48 other satellites from that launch still in the active catalog. As of this element set it had completed roughly 19,858 revolutions of Earth.
Moving at about 7.62 km/s, STARLINK-5691 flies in low Earth orbit at an altitude of roughly 489 × 491 km, completing one revolution every 94.3 minutes — about 15.3 trips around Earth per day. The orbit is essentially circular (eccentricity 0.0002). Its 43.0° inclination keeps its ground track over the tropics and lower mid-latitudes. Its orbital plane crosses the equator northbound at right ascension 13.8°. Earth's equatorial bulge drifts that plane westward about 5.64° per day.

About the Starlink group
STARLINK-5691 is one of 10,717 SpaceX Starlink broadband satellites in the current WatchSat catalog — the largest satellite constellation ever flown. Starlink operates in low-Earth-orbit shells around 540–570 km. See the whole Starlink constellation move live in 3D.
Can you see STARLINK-5691 from the ground?
Sometimes. Like most low-Earth-orbit spacecraft, STARLINK-5691 is visible only around dawn and dusk, when your sky is dark but the satellite is still sunlit — and whether you can spot it depends on its size and reflectivity. See pass predictions for your location for when it is above your horizon and sunlit.
