Question 1

What is the Kp index?

Accepted Answer

The Kp index is a 0–9 scale of global geomagnetic activity. Higher Kp means a stronger geomagnetic storm and aurora visible from lower latitudes. Kp 5+ is an official geomagnetic storm.

Question 2

How far south can the aurora be seen?

Accepted Answer

On tonight's forecast (peak Kp 3.67), the aurora may be visible from latitudes above about 58° in dark, clear skies — lower latitudes need a stronger storm.

Question 3

What time is best to see the aurora?

Accepted Answer

Aurora is best in the hours around local midnight, under a dark, clear sky away from city lights, when geomagnetic activity is elevated. Give your eyes time to adapt and look toward the pole.
