Satellites Visible from London Tonight | ISS & Starlink Pass Times

Q: How high does the ISS appear from London?

Up to 83° on the best passes. From 51.5°N the ISS passes nearly overhead — some passes reach 83° elevation, almost directly above you

Q: Can I see Starlink satellites from London?

8–12 Starlinks above horizon at any time above the horizon at any time. Freshly launched trains are the most spectacular sight.

VIEWING FROM LONDON

YOUR LATITUDE AND WHAT IT MEANS

From 51.5°N the ISS passes nearly overhead — some passes reach 83° elevation, almost directly above you The ISS orbits at a 51.6° inclination, meaning it passes within 51.6° of the equator on each orbit. From London at 51.5°N this creates frequent high-elevation passes overhead when the geometry aligns.

TWILIGHT WINDOW

March–May and September–October offer the best satellite viewing windows. June: astronomical darkness barely arrives — twilight lasts all night near solstice. Satellites are only visible when your sky is dark but the satellite is still in direct sunlight — the twilight window of approximately 45–90 minutes after sunset in spring/autumn. Outside this window satellites are either invisible in daylight or in Earth's shadow.

LIGHT POLLUTION BORTLE 8

City sky — heavy light pollution. The ISS and Tiangong are bright enough to see from central London regardless of light pollution. Individual Starlinks are fainter — best spotted from suburbs or nearby dark sky areas. South Downs National Park (~70km), Brecon Beacons (~250km) offer significantly darker skies.

STARLINK FROM LONDON

At any given moment, 8–12 Starlinks above horizon at any time are above London's horizon. During twilight the sunlit ones are visible to the naked eye. Freshly launched Starlink trains — groups of 20–60 satellites in tight formation — are particularly spectacular and visible for several days after each SpaceX launch. OrbitalNodes.ai detects trains automatically and shows which direction to look.

LOCAL LANDMARK GUIDE

The ISS often rises above the Thames in the SW and crosses toward the NE over the City. Use the compass on your phone to orient yourself before the pass — knowing which direction is SW or NW before it starts makes a big difference. The OrbitalNodes app gives you plain-English directions updated every 2 seconds.

OrbitalNodes.ai calculates exact pass times for London's coordinates — times, directions, and when each satellite is actually visible versus just overhead. No app download needed.

ISS AND SATELLITE FAQ — LONDON

When is the best time to see the ISS from London?

March–May and September–October offer the best satellite viewing windows. The ISS is only visible during twilight — roughly 45–90 minutes after sunset in spring/autumn — when your sky is dark but the station is still in direct sunlight. During this window it appears as a very bright, steady light moving smoothly across the sky in about 4–6 minutes. Check OrbitalNodes.ai for tonight's exact pass time from London.

How high does the ISS appear from London?

From 51.5°N the ISS passes nearly overhead — some passes reach 83° elevation, almost directly above you The elevation varies pass by pass — some nights it skims near the horizon at 20–30°, other nights it passes nearly overhead. Higher elevation passes are brighter (the ISS is closer to you) and give you more time to observe it crossing the sky.

Can I see Starlink satellites from London?

Yes — 8–12 Starlinks above horizon at any time at any one time. Individual satellites are faint but visible from dark suburban areas. The most dramatic sight is a freshly launched Starlink train — a string of 20–60 bright dots in perfect formation that appears several times in the week following each SpaceX launch. OrbitalNodes.ai detects trains automatically and alerts you when one is approaching London.

What direction does the ISS travel from London?

The ISS travels typically SW to NE as seen from London. It always moves in a consistent direction on any given pass — never backwards, never hovering. A useful rule: satellites never blink (aircraft do) and move noticeably faster than the stars. The OrbitalNodes app gives you the exact bearing to watch before the pass begins.

What else can I see in London's sky?

Beyond the ISS and Starlink, Tiangong (China's space station) is nearly as bright as the ISS and passes regularly. Hubble Space Telescope is visible with the naked eye under dark skies. Planets — Venus, Jupiter, Mars and Saturn — are not satellites but are often mistaken for one. OrbitalNodes.ai shows all of these alongside satellite passes.
