What Does Hemisphere Power Mean?
The Northern and Southern Hemisphere Power values indicate the intensity of the auroras and the global energy distribution. The higher these values, the brighter and more widespread the auroras can be. High values mean more active and easily observable auroras.

What is Kp-index?
The Planetary K-index (Kp-index) is a global indicator of geomagnetic storm activity in Earth's magnetic field. It is measured on a scale from 0 to 9, where 0 represents very calm conditions and 9 represents severe geomagnetic storms. The Kp-index is an important indicator for aurora observers; high Kp values mean that auroras can be seen at lower latitudes and more intensely. Values of Kp 5 and above are generally considered a geomagnetic storm and offer good opportunities for aurora viewing.

Solar Wind Conditions for Aurora Viewing
For better aurora viewing, the solar wind speed should be high (>400 km/s) and the Bz component of the magnetic field should be strongly negative (<-5 nT). These conditions allow solar particles to interact more effectively with Earth's magnetosphere, increasing the brightness of the auroras.
