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 Slagelse, Zealand, Denmark?

What time of night is best for aurora watching in Slagelse, Zealand, Denmark?

Auroral substorms cluster around local magnetic midnight, so the hours either side of midnight are statistically strongest. You also need real darkness: this page's dusk and dawn times mark the usable window, and the window is longest around the winter months.

Do I need to leave Slagelse, Zealand, Denmark to see the aurora?

Slagelse, Zealand, Denmark is small enough that local sky glow is not the limiting factor; a clear view toward the northern horizon and clear weather matter more.

Local sky character in Slagelse

Northern mid-latitudes · northern hemisphere · 51 m elevation

The north celestial pole stands 55.4° above the horizon, so stars within 55° of it never set from here.
About 91.2% 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 5.6° up, staying low, so a clear southern horizon matters.
At 51 m elevation, roughly 1% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
