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 Castanhal, Pará, Brazil?

Tonight from Castanhal, Pará, 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 9.6 hours of true astronomical darkness.

What planets are visible tonight in Castanhal, Pará, Brazil?

Tonight in Castanhal, Pará, 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 Castanhal, Pará, Brazil?

Astronomical darkness begins at 7:11 PM local time in Castanhal, Pará, 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 Castanhal, Pará, Brazil?

Castanhal, Pará, 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 Castanhal, Pará, Brazil?

Castanhal, Pará, 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.

Can I see both northern and southern constellations from Castanhal, Pará, Brazil?

Yes — this is the real advantage of an equatorial location. At 1.3° S, about 51.1% 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 Castanhal, Pará, Brazil?

The Galactic Centre culminates around 62.3° 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 Castanhal, Pará, 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 Castanhal, Pará, Brazil tonight?

About 9.6 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.

Tonight's sky above Castanhal, Pará, Brazil

Whether tonight is a good night for stargazing from Castanhal, Pará, Brazil comes down to four real things: the Moon phase, cloud cover, which planets are up, and the current Kp index.

Local sky character in Castanhal

Tropical / equatorial latitudes · southern hemisphere · 46 m elevation

The south celestial pole stands 1.3° above the horizon, so stars within 1° of it never set from here.
About 51.1% 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 62.3° up, clearing the horizon haze comfortably.
The Large Magellanic Cloud only reaches about 21.6° altitude, so it is a low, seasonal target rather than a year-round one.
At 46 m elevation, roughly 1% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
