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 is the stargazing light pollution level in Rio Segundo, Alajuela Province, Costa Rica?

Rio Segundo, Alajuela Province, Costa Rica 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.

Does Rio Segundo, Alajuela Province, Costa Rica's elevation help stargazing?

At 1699 m you are above a meaningful fraction of the atmosphere, which reduces extinction and scintillation — the reason major observatories are sited high.

What should I plan for observing near Rio Segundo, Alajuela Province, Costa Rica?

High sites reward targets that suffer most from atmosphere: planets at high altitude, faint nebulae, and the Milky Way, which culminates around 50.8° here. Cold and thinner air are the practical constraints, not the sky.

How dark does it actually get in Rio Segundo, Alajuela Province, Costa Rica tonight?

About 9.8 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 Rio Segundo

Tropical / equatorial latitudes · northern hemisphere · 1699 m elevation

The north celestial pole stands 10.2° above the horizon, so stars within 10° of it never set from here.
About 58.9% 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 50.8° up, clearing the horizon haze comfortably.
The Large Magellanic Cloud only reaches about 10.1° altitude, so it is a low, seasonal target rather than a year-round one.
At 1699 m elevation, roughly 18% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
