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.

Local sky character in La Plata

Southern mid-latitudes · southern hemisphere · 27 m elevation

The south celestial pole stands 34.9° above the horizon, so stars within 35° of it never set from here.
About 78.6% 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 84.1° up, passing almost directly overhead.
The Large and Small Magellanic Clouds are circumpolar here — visible on any clear, dark night of the year.
At 27 m elevation, roughly 0% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
