EARENDIL-1 Passes
Over Cape Town
Predicted pass geometry, viewing conditions, and beam footprint data for Cape Town when EARENDIL-1 — the first commercial orbital mirror — launches in mid-2026. From 33.9°S at the southern tip of Africa — the exact same latitude as Sydney — EARENDIL-1 reaches up to ~70° peak elevation. Cape Town offers a unique combination of Mediterranean climate, Table Mountain as an elevated vantage point, and proximity to the SAAO Sutherland dark-sky site (~400km NE) — one of the darkest accessible skies in the Southern Hemisphere.
What to Expect in Cape Town
What EARENDIL-1 Will Look Like from Cape Town
From Cape Town, EARENDIL-1 passes will appear as a fast-moving point of light crossing the sky in approximately 3–4 minutes. At peak brightness it will reach magnitude ~−4 — comparable to Venus at maximum and clearly visible even from central Cape Town. The view against the silhouette of Table Mountain, Lion's Head, or Devil's Peak provides one of the most visually distinctive settings of any city on Earth for watching a satellite pass. Cape Town shares the exact same latitude as Sydney — pass geometry is essentially identical.
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.

How bright will EARENDIL-1 appear from Cape Town?
At peak overhead passes, EARENDIL-1 is designed to reach magnitude ~−4 — comparable to Venus at maximum brightness. It is easily visible from the V&A Waterfront, Signal Hill, Lion's Head, or anywhere in Cape Town's City Bowl despite Bortle 7 urban light pollution. The Table Mountain summit (1,086m, accessible by cableway) offers one of the world's most dramatic urban viewing platforms. Between commercial illumination passes, Reflect Orbital tilts the mirror away from Earth, reducing brightness significantly.
How high will EARENDIL-1 appear from Cape Town?
From 33.9°S at the southern tip of Africa, EARENDIL-1 can reach ~70° elevation on the best passes — identical to Sydney which shares the exact same latitude. Passes rise in the NW and transit toward the NE, opposite to the direction seen from northern-hemisphere observers. Cape Town's Cape Peninsula geography gives exceptionally open views to the south over the Atlantic Ocean.
When is the best time to see it from Cape Town?
November through March is Cape Town's summer dry season — reliably clear weather despite strong south-easterly winds (the Cape Doctor). Winter (June–August) brings Atlantic frontal cloud and rain but still produces many clear nights between systems. Autumn and spring are transitional with increasing stability toward summer. The Cederberg and Karoo offer dark-sky destinations within a 3–5 hour drive.
Will the beam footprint hit Cape Town?
A 5km beam footprint could span from the V&A Waterfront to the City Bowl and onto Table Mountain's lower slopes in a single pass — covering virtually all of central Cape Town's iconic tourist landmarks simultaneously. Alternatively, a beam over the Atlantic Seaboard could illuminate Sea Point, Camps Bay, and Clifton beaches with the Atlantic Ocean providing a dramatic reflective backdrop. A pass targeting Table Mountain itself would be globally distinctive — concentrated sunlight on one of the most recognizable natural landmarks on Earth. 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 Cape Town than from other cities?
From the Southern Hemisphere at 33.9°S, EARENDIL-1 rises in the NW and transits toward the NE — opposite to the direction seen from northern cities. This is because Cape Town is south of the equator, so sun-synchronous satellites approach from the polar direction opposite to northern-hemisphere observers. Cape Town shares the same latitude as Sydney and Buenos Aires, so pass geometry is essentially identical in all three cities.
How does Cape Town's Table Mountain geography interact with the 5km beam?
Cape Town's Table Mountain (~1,086m, accessible by cableway) provides one of the most dramatic urban viewing platforms of any major city on Earth — an elevated vantage that rises above the city's light dome. A 5km beam footprint could span from the V&A Waterfront through the City Bowl and onto Table Mountain's lower slopes simultaneously, covering virtually all of central Cape Town's iconic tourist landmarks. Alternatively, a beam over the Atlantic Seaboard could illuminate Sea Point and Clifton beaches with the ocean amplifying the visual effect. A pass targeting Table Mountain itself would be visually distinctive — concentrated sunlight illuminating one of the world's most recognizable natural landmarks. The Cape Peninsula's open southern exposure over the Southern Ocean gives exceptionally clear viewing arcs below the horizon.
What dark-sky locations near Cape Town 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.
