Local sky character in Angra dos Reis
Tropical / equatorial latitudes · southern hemisphere · 8 m elevation
- The south celestial pole stands 23° above the horizon, so stars within 23° of it never set from here.
- About 69.5% of the whole sky rises above the horizon at some point in the year from this latitude.
- The Milky Way's core in Sagittarius culminates about 84° up, passing almost directly overhead.
- The Large and Small Magellanic Clouds are circumpolar here — visible on any clear, dark night of the year.
- At 8 m elevation, roughly 0% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
Angra dos Reis is a town-scale settlement, so the edge of the built-up area is often dark enough for the Milky Way on moonless nights.

Best nights this month in Angra dos Reis
Calculated for these coordinates and today's date — not a fixed list.
- 2026-10-21 — Orionids peak — up to 20/hour
Radiant in Orion. Visible from both hemispheres. The Moon is 72% lit on peak night, so lunar interference is moderate.
- 2026-10-26 — Full Moon
A 100%-lit Moon washes out faint objects, but lunar terrain along the limb is at its most striking — plan bright targets and planets instead of deep sky.
- 2026-11-09 — Darkest night of the coming month
The Moon is only 0% illuminated, giving the least lunar interference in the next 30 nights — the best window for the Milky Way and faint deep-sky targets from Angra dos Reis, Rio de Janeiro, Brazil.

- What is the stargazing light pollution level in Angra dos Reis, Rio de Janeiro, Brazil?
- Angra dos Reis, Rio de Janeiro, Brazil is a small city — typically Bortle class 4–5 (rural/suburban transition), where the Milky Way core can be glimpsed on clear, moonless nights. These are typical ranges for this population size, not a measured reading for this exact spot — use tonight's Moon phase and the best-nights list above to time a visit away from direct lighting.
- Does Angra dos Reis, Rio de Janeiro, Brazil's elevation help stargazing?
- At 8 m you are above a meaningful fraction of the atmosphere, which reduces extinction and scintillation — the reason major observatories are sited high. Pico dos Dias Observatory sits about 140 km from Angra dos Reis, Rio de Janeiro, Brazil at 1864 m.
- What should I plan for observing near Angra dos Reis, Rio de Janeiro, Brazil?
- High sites reward targets that suffer most from atmosphere: planets at high altitude, faint nebulae, and the Milky Way, which culminates around 84° here. Cold and thinner air are the practical constraints, not the sky.
- How dark does it actually get in Angra dos Reis, Rio de Janeiro, Brazil tonight?
