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?

Local sky character in Blumenau

Southern mid-latitudes · southern hemisphere · 20 m elevation

The south celestial pole stands 26.9° above the horizon, so stars within 27° of it never set from here.
About 72.6% 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 87.9° up, passing almost directly overhead.
The Large and Small Magellanic Clouds are circumpolar here — visible on any clear, dark night of the year.
At 20 m elevation, roughly 0% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
