What planets are visible tonight?

Which planets are visible depends on your date and location. Venus, Jupiter, Mars, and Saturn are the four naked-eye planets that are frequently visible; Mercury is visible only in brief windows near sunrise or sunset. Enter your city above and the report will list the planets currently above the horizon after dark.

Can I see the Northern Lights tonight?

Aurora visibility depends on the Kp index and your geomagnetic latitude. At Kp 3, aurora is typically visible only near the Arctic and Antarctic circles. At Kp 5 (a G1 storm), the auroral oval expands south into the northern U.S. and northern Europe. At Kp 7+ it can reach mid-latitudes. The report above compares your latitude to the current auroral boundary in real time.

Is there a meteor shower tonight?

There are around a dozen major meteor showers each year. The report above shows the next active shower and how many days until its peak. For best viewing, look after midnight from a dark location with the shower's radiant above the horizon.

When will the ISS pass over tonight?

The International Space Station passes overhead multiple times per day, but only some passes are visible (bright, after dusk or before dawn, and above the horizon). The report above shows the next visible pass time for your location, computed from live NORAD orbital elements.

What can I see in the sky tonight from Francisco Santos, Piauí, Brazil?

Tonight from Francisco Santos, Piauí, Brazil expect a waxing crescent Moon at 2% illumination, with these naked-eye planets above the horizon after dark: Saturn, Mars, Jupiter, Mercury. The night offers about 9.4 hours of true astronomical darkness.

What planets are visible tonight in Francisco Santos, Piauí, Brazil?

Tonight in Francisco Santos, Piauí, Brazil, Saturn, Mars, Jupiter, Mercury are visible to the naked eye after dark, based on this location's real ephemeris for tonight.

When does darkness start tonight in Francisco Santos, Piauí, Brazil?

Astronomical darkness begins at 6:48 PM local time in Francisco Santos, Piauí, Brazil tonight, the moment the Sun drops more than 18° below the horizon and the sky becomes fully dark for faint-object observing.

Can you see the aurora tonight in Francisco Santos, Piauí, Brazil?

Francisco Santos, Piauí, Brazil is far enough from the pole that aurora only reaches overhead during a major geomagnetic storm — specifically when the planetary Kp index reaches about 9, a level reached only a handful of times per solar cycle.

What is the stargazing light pollution level in Francisco Santos, Piauí, Brazil?

Francisco Santos, Piauí, Brazil is a small town — typically Bortle class 1–4 (rural to excellent dark sky), where the Milky Way is usually visible on clear, moonless nights away from local lighting. 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.

Can I see both northern and southern constellations from Francisco Santos, Piauí, Brazil?

Yes — this is the real advantage of an equatorial location. At 7.0° S, about 56.1% of the entire celestial sphere rises at some point in the year, so Polaris-side constellations and the Southern Cross region are both reachable across the seasons.

How good is the Milky Way from Francisco Santos, Piauí, Brazil?

The Galactic Centre culminates around 68° above the horizon from here, high enough to clear most horizon haze. Local cloud and humidity, not geometry, are usually the limiting factor at tropical latitudes.

Are there seasons for stargazing in Francisco Santos, Piauí, Brazil?

Night length barely changes at this latitude — twilight is short and the Sun sets steeply, so darkness arrives quickly all year. What changes is which part of the sky is on view after sunset, and, in monsoon-affected regions, how often the sky is clear at all.

How dark does it actually get in Francisco Santos, Piauí, Brazil tonight?

About 9.4 hours of astronomical darkness (Sun more than 18° below the horizon). That is the real observing window for faint objects; brighter targets are workable from dusk onward.

Local sky character in Francisco Santos

Tropical / equatorial latitudes · southern hemisphere · 252 m elevation

The south celestial pole stands 7° above the horizon, so stars within 7° of it never set from here.
About 56.1% 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 68° up, clearing the horizon haze comfortably.
The Large Magellanic Cloud only reaches about 27.3° altitude, so it is a low, seasonal target rather than a year-round one.
At 252 m elevation, roughly 3% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.

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.
2026-10-25 — 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.
2026-11-08 — 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 Francisco Santos, Piauí, Brazil.
