What do Kp, geomagnetic storm and aurora mean?
Kp

It is a global index from 0 to 9 showing how disturbed Earth's magnetic field is. The higher Kp is, the stronger the geomagnetic activity.

G1–G5

This is the scale used for geomagnetic storms. G1 means a minor storm and G5 an extreme storm. G levels generally begin at Kp 5.

Aurora borealis

It is light produced when charged particles from the Sun interact with Earth's upper atmosphere and magnetic field.

Can it be seen from Romania?

Usually not. Strong geomagnetic storms, clear skies, an unobstructed northern horizon and low light pollution are needed. Even with a high Kp, visibility is not guaranteed.

Kp describes geomagnetic activity on a planetary scale. By itself, it is not an exact forecast of aurora visibility in a specific city.
