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 Hennef (Sieg), North Rhine-Westphalia, Germany?

Tonight from Hennef (Sieg), North Rhine-Westphalia, Germany expect a new moon Moon at 0% illumination, with these naked-eye planets above the horizon after dark: Venus, Jupiter, Mercury, Saturn, Mars. The night offers about 4.7 hours of true astronomical darkness.

Does Hennef (Sieg), North Rhine-Westphalia, Germany's elevation help stargazing?

At 70 m you are above a meaningful fraction of the atmosphere, which reduces extinction and scintillation — the reason major observatories are sited high. Effelsberg Radio Telescope sits about 40 km from Hennef (Sieg), North Rhine-Westphalia, Germany at 319 m.

What should I plan for observing near Hennef (Sieg), North Rhine-Westphalia, Germany?

High sites reward targets that suffer most from atmosphere: planets at high altitude, faint nebulae, and the Milky Way, which culminates around 10.2° here. Cold and thinner air are the practical constraints, not the sky.

How dark does it actually get in Hennef (Sieg), North Rhine-Westphalia, Germany tonight?

About 4.7 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 Hennef (Sieg)

Northern mid-latitudes · northern hemisphere · 70 m elevation

The north celestial pole stands 50.8° above the horizon, so stars within 51° of it never set from here.
About 88.7% 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 10.2° up, staying low, so a clear southern horizon matters.
At 70 m elevation, roughly 1% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
