EARENDIL-1 Passes
Over Lagos
Predicted pass geometry, viewing conditions, and beam footprint data for Lagos when EARENDIL-1 — the first commercial orbital mirror — launches in mid-2026. From 6.5°N — almost at the equator — EARENDIL-1 reaches up to ~84° peak elevation, essentially directly overhead. Lagos, Africa's most populous city and one of the world's largest equatorial metros, offers unique near-zenith viewing geometry. Passes can approach from various directions given the near-equatorial latitude, but the overhead peak elevation is consistent.
What to Expect in Lagos
What EARENDIL-1 Will Look Like from Lagos
From Lagos, EARENDIL-1 passes will appear as a fast-moving point of light crossing the sky — and like Bangkok and Mumbai, the mirror passes essentially directly overhead. At peak brightness it reaches magnitude ~−4 — comparable to Venus at maximum. With 84° peak elevation the mirror's path traces nearly vertically across the sky, giving Lagos observers a visual experience distinct from mid-latitude cities where the mirror arcs across the horizon. Tropical haze softens star backgrounds but the mirror remains clearly visible.
The mirror is steerable — between targeted commercial passes, Reflect Orbital tilts it away from Earth, making it much dimmer or invisible. During an active commercial pass you'll see a sudden brightening as the beam angle locks onto the target region. The pass ends abruptly when the mirror tilts away again.
Unlike a steady satellite, EARENDIL-1 may show subtle brightness variations as the mirror adjusts its aim. Watch for a brief period of maximum brightness near the peak of the pass when the geometry is optimal — this is when the 5km ground footprint is directly beneath the mirror at closest approach.

◈ OPEN ORBITALNODES.AISpace Mirror Questions — Lagos
How bright will EARENDIL-1 appear from Lagos?
At peak overhead passes, EARENDIL-1 is designed to reach magnitude ~−4 — comparable to Venus at maximum brightness. Lagos' 84° near-zenith peak elevation means the mirror passes directly overhead, minimizing atmospheric path length and enhancing apparent brightness despite the tropical haze that characterizes the West African coast. It is easily visible from Bar Beach, the Lekki-Ikoyi Link Bridge, or any open coastal location — though Lagos' Bortle 8–9 light pollution means nearby stars fade against the city glow. Between commercial illumination passes, Reflect Orbital tilts the mirror away from Earth, reducing brightness significantly.
How high will EARENDIL-1 appear from Lagos?
From 6.5°N near the equator in coastal West Africa, EARENDIL-1 can reach ~84° elevation on the best passes — essentially directly overhead. This is among the highest peak elevations of any major city in the world — comparable only to Bangkok (13.8°N), Singapore (1.4°N), Bogotá, Kuala Lumpur, and other near-equatorial capitals. Near-equatorial latitudes produce highly variable pass directions: passes can approach from either the SW or NW depending on the orbital plane's relationship to the sun-terminator line.
When is the best time to see it from Lagos?
November through March is Lagos' dry season — less humidity, fewer storms, and the Harmattan winds from December through February bring dry Saharan air with significantly lower humidity despite some dust haze. April through October is the wet season with afternoon storms often clearing by late evening. November and March are the best viewing windows.
Will the beam footprint hit Lagos?
A 5km beam footprint could span from Lagos Island across the lagoon to Victoria Island and onto Lekki Phase 1 in a single pass — covering the city's major financial, political, and cultural districts simultaneously. Alternatively, a beam over the emerging Eko Atlantic City (the massive Atlantic land-reclamation development being built as West Africa's new financial capital) could illuminate what represents one of Africa's most ambitious urban planning projects. A pass along Bar Beach would illuminate the Atlantic shoreline with dramatic water-reflection effects. A beam over National Stadium Surulere or Tafawa Balewa Square could illuminate sites of major national events. Whether any specific location falls in the footprint depends on Reflect Orbital's commercial contracts and targeting decisions.
Is EARENDIL-1 visible yet?
No — EARENDIL-1 has not launched yet. Reflect Orbital is targeting a mid-2026 launch. There is currently no space mirror in Earth orbit. OrbitalSolar.ai will update with live pass data from the moment orbital elements are published after launch. Check the mission tracker for current launch status.
Why does the mirror move differently from Lagos than from other cities?
From near-equatorial latitudes at 6.5°N, EARENDIL-1 passes essentially directly overhead. Compared to mid-latitude northern cities like London or New York where the mirror arcs at moderate elevations, Lagos observers see the mirror tracking almost vertically across the sky. Near-equatorial cities also experience highly variable pass directions — depending on the orbital plane's relationship to the sun-terminator line, passes can approach from either the SW or NW. Sun-synchronous satellites track the day-night boundary, which at equatorial latitudes can approach from essentially any azimuth.
What makes Lagos unique for EARENDIL-1 viewing?
Lagos' 6.5°N equatorial latitude gives it among the highest peak elevations for EARENDIL-1 of any major city on Earth — ~84°, essentially directly overhead. As Africa's most populous city and the only equatorial African megacity in this coverage, Lagos offers a viewing perspective shared by only a handful of other major metros: Bangkok, Singapore, Bogotá, Kuala Lumpur, and Jakarta. The mirror's path traces nearly vertically across the sky at peak pass. Lagos' coastal geography — built across islands (Lagos Island, Victoria Island, Ikoyi, Lekki) separated by lagoons and fronting the Atlantic Ocean — provides unobstructed southern horizons for tracking passes toward the sea. The emerging Eko Atlantic City development on reclaimed Atlantic land creates a unique urban viewing context.
What dark-sky locations near Lagos are best for watching the mirror pass?
The Blue Mountains (90 minutes west, Bortle 3–4) give the clearest sky with minimal light dome interference. Ku-ring-gai Chase National Park (45 minutes north) is excellent for clear northern passes. Royal National Park (45 minutes south) has a clear southern horizon. For serious observation, Observatory Hill in the CBD works for the bright mirror itself — at magnitude −4 it needs no dark sky — but the Blue Mountains are far better for seeing the beam footprint effect against a dark sky backdrop.
